Upgrade path to add additional include to named.conf is not handled.

Remove bindkeys-file directive from named config
The ISC DVL service was shut down (https://www.isc.org/bind-keys/).
BIND versions since April 2017 (i.e. 9.9.10, 9.10.5, 9.11.1 and later)
include a hard-coded copy of the root KSK which gets updates automatically
according to RFC 5011.

Move dnssec-enable directive to custom named config

Move comment named config being managed by FreeIPA to the top

Move settings which could be changed by administrators to
ipa-options-ext.conf. Settings defined there are sole responsibility of the
administrator. We do not check if they might collide with our settings in
named.conf.

3665ba928b ipa-backup: Make sure all roles are installed on the current master.
ipa-backup does not check whether the IPA master it is running on has
all used roles installed. This can lead into situations where backups
are done on a CAless or KRAless host while these roles are used in the
IPA cluster. These backups cannot be used to restore a complete cluster.

With this change, ipa-backup refuses to execute if the roles installed
on the current host do not match the list of roles used in the cluster.

cf4c2c64b0 upgrade: add ipa-ca.$DOMAIN alias to HTTP certificate
For detailed discussion on the purpose of this change and the design
decisions made, see `git log -1 $THIS_COMMIT~3`.

If the HTTP certificate does not have the ipa-ca.$DOMAIN dNSName,
resubmit the certificate request to add the name.  This action is
performed after the tracking request has already been updated.

Note: due to https://pagure.io/certmonger/issue/143, the resubmitted
request, if it does not immediately succeed (fairly likely during
ipa-server-upgrade) and if the notAfter date of the current cert is
still far off (also likely), then Certmonger will wait 7 days before
trying again (unless restarted).  There is not much we can do about
that in the middle of ipa-server-upgrade.

4cf9c8689f httpinstance: add fqdn and ipa-ca alias to Certmonger request
BACKGROUND:

We are implementing ACME support in FreeIPA (umbrella ticket:
https://pagure.io/freeipa/issue/4751).  ACME is defined in RFC 8555.
HTTPS is REQUIRED (https://tools.ietf.org/html/rfc8555#section-6.1).
Therefore, every FreeIPA server that provides the ACME service
capability must be reachable by HTTPS.

RFC 8555 does not say anything about which port to use for ACME.
The default HTTPS port of 443 is implied.  Therefore, the FreeIPA
ACME service will be reached via the Apache httpd server, which will
be the TLS server endpoint.

As a usability affordance for ACME clients, and as a maintainability
consideration i.e. to allow the topology to change without having to
reconfigure ACME clients, there should be a a single DNS name used
to reach the IPA ACME service.

The question then, is which DNS name to use.

REQUIREMENTS:

Each FreeIPA server that is also an ACME server must:

1. Be reachable via a common DNS name

2. Have an HTTP service certificate with that DNS name as a SAN
   dNSName value

DESIGN CONSIDERATION - WHAT DNS NAME TO USE?:

Some unrelated FreeIPA ACME design decisions provide important
context for the DNS name decision:

- The ACME service will be automatically and unconditionally
  deployed (but not necessarily *enabled*) on all CA servers.

- Enabling or disabling the ACME service will have topology-wide
  effect, i.e. the ACME service is either enabled on all CA
  servers, or disabled on all CA servers.

In a CA-ful FreeIPA deployment there is already a DNS name that
resolves to all CA servers: ``ipa-ca.$DOMAIN``, e.g.
``ipa-ca.example.com``.  It is expected to point to all CA servers
in the deployment, and *only* to CA servers.  If internal DNS is
deployed, the DNS records for ``ipa-ca.$DOMAIN`` are created and
updated automatically.  If internal DNS is not deployed,
administrators are required to maintain these DNS records
themselves.

The ``ipa-ca.$DOMAIN`` alias is currently used for OCSP and CRL
access.  TLS is not required for these applications (and it can
actually be problematic for OCSP).  Enabling TLS for this name
presents some risk of confusion for operators.  For example, if they
see that TLS is available and alter the certificate profiles to
include an HTTPS OCSP URL in the Authority Information Access (AIA)
extension, OCSP-using clients may fail to validate such
certificates.  But it is possible for administrators to make such a
change to the profile, whether or not HTTPS is available.

One big advantage to using the ``ipa-ca.$DOMAIN`` DNS name is that
there are no new DNS records to manage, either in the FreeIPA
implementation or for administrators in external DNS systems.

The alternative approach is to define a new DNS name, e.g.
``ipa-acme.$DOMAIN``, that ACME clients would use.  For internal
DNS, this means the FreeIPA implementation must manage the DNS
records.  This is straightforward; whenever we add or remove an
``ipa-ca.$DOMAIN`` record, also add/remove the ``ipa-acme.$DOMAIN``
record.  But for CA-ful deployments using external DNS, it is
additional work for adminstrators and, unless automated, additional
room for error.

An advantage of using a different DNS name is ``ipa-ca.$DOMAIN`` can
remain inaccessible over HTTPS.  This possibly reduces the risk of
administrator confusion or creation of invalid AIA configuration in
certificate profiles.

Weighing up the advantages and disadvantages, I decided to use the
``ipa-ca.$DOMAIN`` DNS name.

DESIGN CONSIDERATION - CA SERVERS, OR ALL SERVERS?:

A separate decision from which name to use is whether to include it
on the HTTP service certificate for ACME servers (i.e. CA servers)
only, or on all IPA servers.

Combined with the assumption that the chosen DNS name points to CA
servers *only*, there does not seem to be any harm in adding it to
the certificates on all IPA servers.

The alternative is to only include the chosen DNS name on the HTTP
service certificates of CA servers.  This approach entails some
additional complexity:

- If a non-CA replica gets promoted to CA replica (i.e. via
  ``ipa-ca-install``), its HTTP certificate must be re-issued with
  the relevant name.

- ipa-server-upgrade code must consider whether the server is a CA
  replica when validating (and if necessary re-creating) Certmonger
  tracking requests

- IPA Health Check must be made aware of this factor when checking
  certificates and Certmonger tracking requests.

Weighing up the options, I decided to add the common DNS name to the
HTTP service certificate on all IPA servers.  This avoids the
implementation complexity discussed above.

CHANGES IN THIS COMMIT

When (re-)tracking the HTTP certificate, explicitly add the server
FQDN and ipa-ca.$DOMAIN DNS names to the Certmonger tracking request.

Related changes follow in subsequent commits.

911992b8bf ipa-adtrust-install: run remote configuration for new agents
When ipa-adtrust-install is run, the tool detects masters that are
not enabled as trust agents and propose to configure them. With the
current code, the Schema Compat plugin is not enabled on these new
trust agents and a manual restart of LDAP server + SSSD is required.

With this commit, ipa-adtrust-install now calls remote code on the new
agents through JSON RPC api, in order to configure the missing parts.
On the remote agent, the command is using DBus and oddjob to launch
a new command,
/usr/libexec/ipa/oddjob/org.freeipa.server.trust-enable-agent [--enable-compat]
This command configures the Schema Compat plugin if --enable-compat is
provided, then restarts LDAP server and SSSD.

If the remote agent is an older version and does not support remote
enablement, or if the remote server is not responding, the tool
ipa-adtrust-install prints a WARNING explaining the steps that need
to be manually executed in order to complete the installation, and
exits successfully (keeping the current behavior).

edfe95b120 Removed hard-coded default profile subsystem class name
Previously in order to enable the LDAP profile subsystem
the ca_enable_ldap_profile_subsystem() would check the
current value of the profile subsystem class parameter in
CS.cfg. If the parameter was still set to the default value
(i.e. ProfileSubsystem), the code would change it to
LDAPProfileSubsystem.

There is a effort in PKI to clean up the profile subsystem
classes which may require changing the default value for
this parameter. However, this improvement is blocked since
the ca_enable_ldap_profile_subsystem() is implicitly assuming
that the default value will always be ProfileSubsystem.

This patch modifies the code such that instead of checking
for a specific value that needs to be changed, it will check
whether it has the desired value already. This mechanism
will reduce potential conflicts with future PKI improvements.

769180c2c6 Do not renew externally-signed CA as self-signed
Commit 49cf5ec64b fixed a bug that
prevented migration from externally-signed to self-signed IPA CA.
But it introduced a subtle new issue: certmonger-initiated renewal
renews an externally-signed IPA CA as a self-signed CA.

To resolve this issue, introduce the `--force-self-signed' flag for
the dogtag-ipa-ca-renew-agent script.  Add another certmonger CA
definition that calls this script with the `--force-self-signed'
flag.  Update dogtag-ipa-ca-renew-agent to only issue a self-signed
CA certificate if the existing certificate is self-signed or if
`--force-self-signed' was given.  Update `ipa-cacert-manage renew'
to supply `--force-self-signed' when appropriate.

As a result of these changes, certmonger-initiated renewal of an
externally-signed IPA CA certificate will not issue a self-signed
certificate.

6c27104467 Prevents DNS Amplification Attack and allow to customize named
While [1] did open recursion, it also opened widely a security flaw.

This patch intends to close it back, while allowing operators to easily
add their open configuration within Bind9.

In order to allow operators to still open Bind recursion, a new file is
introduced, "ipa-ext.conf" (path might change according to the OS). This
file is not managed by the installer, meaning changes to it won't be
overridden.
Since it's included at the very end of the main configuration file, it
also allows to override some defaults - of course, operators have to be
careful with that.

To use fresh renewals the tracking request must record the profile

tracking requests for both CA and KRA.

Note that 'Server-Cert cert-pki-ca' and the 'IPA RA' both use
profile 'caServerCert', which is the default (according to

a43100badc Don't configure disabled krb5 enctypes in FIPS mode
The only permitted ciphers are the AES family (called aes, which
is the combination of: aes256-cts-hmac-sha1-96,
aes128-cts-hmac-sha1-96, aes256-cts-hmac-sha384-192, and
aes128-cts-hmac-sha256-128).

DES, RC4, and Camellia are not permitted in FIPS mode.  While 3DES
is permitted, the KDF used for it in krb5 is not, and Microsoft
doesn't implement 3DES anyway.

This is only applied on new installations because we don't
allow converting a non-FIPS install into a FIPS one.

814592cf22 ipa-client-samba: a tool to configure Samba domain member on IPA client
Introduces new utility to configure Samba on an IPA domain member.

The tool sets up Samba configuration and internal databases, creates
cifs/... Kerberos service and makes sure that a keytab for this service
contains the key with the same randomly generated password that is set
in the internal Samba databases.

Samba configuration is created by querying an IPA master about details
of trust to Active Directory configuration. All known identity ranges
added to the configuration to allow Samba to properly handle them
(read-only) via idmap_sss.

Resulting configuration allows connection with both NTLMSSP and Kerberos
authentication for IPA users. Access controls for the shared content
should be set by utilizing POSIX ACLs on the file system under a
specific share.

The utility is packaged as freeipa-client-samba package to allow pulling
in all required dependencies for Samba and cifs.ko (smb3.ko) kernel
module. This allows an IPA client to become both an SMB server and an
SMB client.

d631e008cc adtrust: update Samba domain controller keytab with host keys
When DCERPC clients use Kerberos authentication, they use a service
ticket to host/domain.controller because in Active Directory any
service on the host is an alias to the machine account object.

In FreeIPA each Kerberos service has own keys so host/.. and cifs/..
do not share the same keys. It means Samba suite needs to have access to
host/.. keytab entries to validate incoming DCERPC requests.

Unfortunately, MIT Kerberos has no means to operate on multiple keytabs
at the same time and Samba doesn't implement this either. We cannot use
GSS-Proxy as well because Samba daemons are running under root.

As a workaround, copy missing aes256 and aes128 keys from the host
keytab. SMB protocol doesn't use other encryption types and we don't
have rc4-hmac for the host either.

If the packages are not installed full backup should be refused and an error message with suggestions should be showed.

If corresponding packages for these features are not installed before the backup restoring, it may cause a situation when the packages are going to be installed after the restoring. In that case configuration files restored by `ipa-restore` will be replaced by default configuration files if the files are tracked by `rpm`. E.g. if `freeipa-server-trust-ad` is not installed before `ipa-restore --full` running, when the package will be installed it also will bring `samba` package according to the dependencies. At `samba` installation step exist correct `/etc/samba/smb.conf` is going to be replaced by the default one from the `samba` package.

effectively disabling any allocation on those domains that we don't need

Note that 'idmap config <domain> : range' parameter accepts range in a

3f9e23f125 Add ExecStartPost hook to wait for Dogtag PKI
Dogtag PKI typically takes around 10 seconds to start and respond to
requests. Dogtag uses a simple systemd service, which means systemd is
unable to detect when Dogtag is ready. Commands like ``systemctl start``
and ``systemctl restart`` don't block and wait until the CA is up. There
have been various workarounds in Dogtag and IPA.

Systemd has an ExecStartPost hook to run programs after the main service
is started. The post hook blocks systemctl start and restart until all
post hooks report ready, too. The new ipa-pki-wait-running script polls
on port 8080 and waits until the CA subsystem returns ``running``.

80928ba6f5 Use Network Manager to configure resolv.conf
IPA used to write a custom /etc/resolv.conf. On Fedora and RHEL,
NetworkManager is typically maintaining resolv.conf. On reboot or
restart of the service, NM overwrites the custom settings.

On systems with NM enabled, the DNS server installer now drops a config
file into NM's global config directory and delegates resolv.conf to NM.

On systems without NM, fall back to create /etc/resolv.conf directly.

b79ea6a6e9 Fix wrong evaluation of attributes in check_repl_update
The method check_repl_update in ipaserver/install/replication.py badly
handles the attributes nsds5ReplicaLastUpdateStart and
nsds5ReplicaLastUpdateEnd as it expects them to contain an int.
These attributes are defined as GeneralizedTime
(OID 1.3.6.1.4.1.1466.115.121.1.24, for instance
nsds5ReplicaLastUpdateEnd='20190412122523Z') but older versions of 389-ds can
also return the value 0 for uninitialized values (see 389-ds ticket 47836).
The code must be able to handle the generalized time format or the 0 value.

The fix removes the 'Z' from the GeneralizedTime and converts to an int,
or assigns 0.

The installer (executed as root) currently creates a file in /tmp,
then modifies its owner to pkiuser and finally writes the pki config
in the file. With fs.protected_regular=1, the write is denied because
root is not owner of the file at this point.
The fix performs the ownership change after the file has been written.

Currently, the replica installation fails because the installer is
trying to add a A/AAAA record for the replica in the zone
when setting up the bind instance, and addition of records in a

The bind installer should check if the IP address is in a master zone
(i.e. a DNS zone managed by IdM, not a forward zone), and avoid
creating the record if it's not the case.

During uninstallation, perform the same check before removing the

c0fd5e39c7 replica install: set the same master as preferred source for domain and CA
During ipa-replica-install, the installer creates a ReplicaConfig
object that contains a config.ca_host_name attribute, built from
api.env.ca_host.
This attribute is used as preferred source when asking the DNS for a CA
master from which to initialize the CA instance
(see commit 8decef33 for master selection and preferred host).

In most of the cases, /etc/ipa/default.conf does not contain any
definition for ca_host. In this case, api.env.ca_host is set to
the local hostname.
As a consequence, replica install is trying to use the local host
as preferred source (which does not have any CA yet), and the method
to find the CA source randomly picks the CA in the DNS.

With the fix, the master picked for domain replication is also used as
preferred source for CA/KRA.

faa122a8b8 replication: check remote ds version before editing attributes
When the remote server has an old DS version, update of the
replication attributes nsds5ReplicaReleaseTimeout nsds5ReplicaBackoffMax
and nsDS5ReplicaBindDnGroupCheckInterval fails even if the remote
schema has been updated.

Check first the remote server version and update the attributes only if
the version is high enough.
A previous fix was already performing this check (commit 02f4a7a),
but not in all the cases. This fix also handles when the remote server
already has a cn=replica entry (for instance because it has already
established replication with another host).

a230153837 PKINIT: fix ipa-pkinit-manage enable|disable
The command ipa-pkinit-manage enable|disable is reporting
success even though the PKINIT cert is not re-issued.
The command triggers the request of a new certificate
(signed by IPA CA when state=enable, selfsigned when disabled),
but as the cert file is still present, certmonger does not create
a new request and the existing certificate is kept.

The fix consists in deleting the cert and key file before calling
certmonger to request a new cert.

There was also an issue in the is_pkinit_enabled() function:
if no tracking request was found for the PKINIT cert,
is_pkinit_enabled() was returning True while it should not.

800f2690f5 ipa upgrade: handle double-encoded certificates
Issue is linked to the ticket
 #3477 LDAP upload CA cert sometimes double-encodes the value
In old FreeIPA releases (< 3.2), the upgrade plugin was encoding twice
the value of the certificate in cn=cacert,cn=ipa,cn=etc,$BASEDN.

The fix for 3477 is only partial as it prevents double-encoding when a
new cert is uploaded but does not fix wrong values already present in LDAP.

With this commit, the code first tries to read a der cert. If it fails,
it logs a debug message and re-writes the value caCertificate;binary
to repair the entry.

Fix Coverity finding CID 323644: logically dead code path

The code to determine whether NetBIOS name was already set or need to be
set after deriving it from a domain or asking a user for an interactive
input, was refactored at some point to avoid retrieving the whole LDAP
entry. Instead, it was provided with the actual NetBIOS name retrieved.

As result, a part of the code got neglected and was never executed.

Fix this code and provide a test that tries to test predefined,
interactively provided and automatically derived NetBIOS name depending
on how the installer is being run.

3b79deae53 net groupmap: force using empty config when mapping Guests
When we define a group mapping for BUILTIN\Guests to 'nobody' group in
we run 'net groupmap add ...' with a default /etc/samba/smb.conf which
is now configured to use ipasam passdb module. We authenticate to LDAP
with GSSAPI in ipasam passdb module initialization.

If GSSAPI authentication failed (KDC is offline, for example, during
server upgrade), 'net groupmap add' crashes after ~10 attempts to
re-authenticate. This is intended behavior in smbd/winbindd as they
cannot work anymore. However, for the command line tools there are
plenty of operations where passdb module is not needed.

Additionally, GSSAPI authentication uses the default ccache in the
environment and a key from /etc/samba/samba.keytab keytab. This means
that if you'd run 'net *' as root, it will replace whatever Kerberos
tickets you have with a TGT for cifs/`hostname` and a service ticket to
ldap/`hostname` of IPA master.

Apply a simple solution to avoid using /etc/samba/smb.conf when we
set up the group mapping by specifying '-s /dev/null' in 'net groupmap'
call.

For upgrade code this is enough as in
a678336b8b we enforce use of empty
credentials cache during upgrade to prevent tripping on individual
ccaches from KEYRING: or KCM: cache collections.

1ef0fe8bb8 adtrust: define Guests mapping after creating cifs/ principal
All Samba utilities load passdb modules from the configuration file. As
result, 'net groupmap' call would try to initialize ipasam passdb module
and that one would try to connect to LDAP using Kerberos authentication.

We should be running it after cifs/ principal is actually created in
ipa-adtrust-install or otherwise setting up group mapping will fail.

This only affects new installations. For older ones 'net groupmap' would
work just fine because adtrust is already configured and all principals
exist already.

A re-run of 'ipa-server-upgrade' is a workaround too but better to fix
the initial setup.
