3cf9979aec ipa-client-install: use sshd drop-in configuration
sshd 8.2+ now supports the "Include" keyword in sshd_config and
ships by default /etc/ssh/sshd_config with
"Include /etc/ssh/sshd_config.d/*"

As fedora 32 provides a config file in that directory (05-redhat.conf) with
ChallengeResponseAuthentication no
that is conflicting with IPA client config, ipa-client-install now needs
to make its config changes in a drop-in file read before 05-redhat.conf
(the files are read in lexicographic order and the first setting wins).

There is no need to handle upgrades from sshd < 8.2: if openssh-server
detects a customisation in /etc/ssh/sshd_config, it will not update
the file but create /etc/ssh/sshd_config.rpmnew and ask the admin
to manually handle the config upgrade.

3ecea7800a Configure PKI AJP Secret with 256-bit secret
By default, PKI's AJP secret is generated as a 75-bit password. By
generating it in IPA, we can guarantee the strength of the AJP secret.
It makes sense to use a stronger AJP secret because it typically
isn't rotated; access to AJP allows an attacker to impersonate an admin
while talking to PKI.

c5e9bd61d6 Clarify AJP connector creation process
We do two things:

 1. Fix the xpath for AJP connector verification. An AJP connector is
    one which has protocol="AJP/1.3", NOT one that has port="8009". An
    AJP connector can exist on any port and port 8009 can have any
    protocol. Secrets only make sense on AJP connectors, so make the
    xpath match the existing comment.

 2. Add some background in-line documentation about AJP secret
    provisioning. This should help future developers understand why this
    was added to IPA and what limitations there are in what PKI or IPA
    can do. Most notably, explain why Dogtag can't upgrade the AJP
    connector to have a secret in the general case.

4911a3f055 Prevent local account takeover
It was found that if an account was created with a name corresponding to
an account local to a system, such as 'root', was created via IPA, such
account could access any enrolled machine with that account, and the local
system privileges. This also bypass the absence of explicit HBAC rules.

root principal alias
-------------------

The principal "root@REALM" is now a Kerberos principal alias for
"admin". This prevent user with "User Administrator" role or
"System: Add User" privilege to create an account with "root" principal
name.

Modified user permissions
-------------------------

Several user permissions no longer apply to admin users and filter on
posixaccount object class. This prevents user managers from modifying admin
acounts.

- System: Manage User Certificates
- System: Manage User Principals
- System: Manage User SSH Public Keys
- System: Modify Users
- System: Remove Users
- System: Unlock user

``System: Unlock User`` is restricted because the permission also allow a
user manager to lock an admin account. ``System: Modify Users`` is restricted
to prevent user managers from changing login shell or notification channels
(mail, mobile) of admin accounts.

New user permission
-------------------

- System: Change Admin User password

The new permission allows manipulation of admin user password fields. By
default only the ``PassSync Service`` privilege is allowed to modify
admin user password fields.

Modified group permissions
--------------------------

Group permissions are now restricted as well. Group admins can no longer
modify the admins group and are limited to groups with object class
``ipausergroup``.

- System: Modify Groups
- System: Remove Groups

The permission ``System: Modify Group Membership`` was already limited.

Notes
-----

Admin users are mostly unaffected by the new restrictions, except for
the fact that admins can no longer change krbPrincipalAlias of another
admin or manipulate password fields directly. Commands like ``ipa passwd
otheradmin`` still work, though. The ACI ``Admin can manage any entry``
allows admins to modify other entries and most attributes.

Managed permissions don't install ``obj.permission_filter_objectclasses``
when ``ipapermtargetfilter`` is set. Group and user objects now have a
``permission_filter_objectclasses_string`` attribute that is used
by new target filters.

Misc changes
------------

Also add new exception AlreadyContainsValueError. BaseLDAPAddAttribute
was raising a generic base class for LDAP execution errors.

f52a15b808 Overhaul bind upgrade process
/etc/named.conf is now owned by IPA. The file is overwritten on
installation and all subsequent updates. All user modification will be
lost. Config file creation and update use the same code paths.

This simplifies upgrade process a lot. There is no errprone fiddling
with config settings any more.

During upgrade there is a one-time backup of named.conf to
named.conf.ipa-backup. It allows users to salvage their customization
and move them to one of two user config files which are included by
named.conf.

e6fda6f0fb upgrade: avoid stopping certmonger when fixing requests
During upgrade, if discrepancies are detected in Certmonger tracking
request configuration we remove and re-create tracking requests.
The default behaviour of the CAInstance and KRAInstance
stop_tracking_certificates() method is to stop certmonger after the
requests have been removed.  This behaviour results in an
unnecessary restart of certmonger and has also been observed to
cause problems.  For example, subsequent certmonger operations have
to start the certmonger process and can fail because certmonger is
not yet properly initialised (manifesting as D-Bus errors).

Suppress the unnecessary restart(s) of certmonger during tracking
request update.

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

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.

b6865831c9 DnsSecMaster migration: move the call to zonelist export later
When migrating the DNSSec Master to a replica, the setup of
opendnssec is re-using the database and needs to call zonelist
export.
With opendnssec 1.4 this call is done with ods-ksmutil while
opendnssec 2.1 uses ods-enforcer that communicates with
odsenforcerd that is not started yet.
Move the call after ods-enforcerd is started.

8080bf7b35 Support OpenDNSSEC 2.1: new ods-signer protocol
The communication between ods-signer and the socket-activated process
has changed with OpenDNSSEC 2.1. Adapt ipa-ods-exporter to support also
the new protocol.

The internal database was also modified. Add a wrapper calling the
right code (table names hab=ve changed, as well as table columns).

With OpenDNSSEC the policy also needs to be explicitely loaded after
ods-enforcer-db-setup has been run, with
ods-enforcer policy import

The command ods-ksmutil notify must be replace with ods-enforce flush.

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).

ba12165eaf lint: Make Pylint-2.4 happy again
This is the first time running Pylint-2.4 over the whole IPA codebase.

Pylint on /usr/bin/python is running, please wait ...
internal error with sending report for module ['ipaserver/plugins/serverroles.py']

The latest Pylint (via the Tox task) checks only:
```
{envsitepackagesdir}/ipaclient \
{envsitepackagesdir}/ipalib \
{envsitepackagesdir}/ipapython
```

, while the distro-Pylint runs over all project but it is not fresh.
That's why these warnings/errors weren't exposed before now.

Concerning `internal error`: a fix was accepted by upstream:
https://github.com/PyCQA/pylint/issues/3245, but wasn't released yet.
Until that is done, Pylint just warns.

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.

if options.force and options.allow_zone_overlap are both false and the
reverse zone check later on was still handling ValueError instead of
dnsutil.DNSZoneAlreadyExists.

Both issues have been fixed and the deployment with existing name servers
is properly working again.

When re-running `ipa-server-install --setup-dns` on already installed
server, we do not get to the check of being already installed because
DNS zone overlap forces us to fail earlier.

Change exception returned for this case from check_zone_overlap() to
return structured information that allows to understand whether we are
finding a conflict with ourselves.

Use the returned information to only fail DNS check at this point if DNS
zone overlap is generated by a different name server than ourselves.
