a137eee815 Remove deprecation warning when installing a CA replica
I got the following message when installing a replica with CA:

2021-11-22T21:15:35Z DEBUG   [5/30]: configuring certificate server instance

...
WARNING: The 'pki_ssl_server_token' in [CA] has been deprecated. Use 'pki_sslserver_token' instead.
Installation log: /var/log/pki/pki-ca-spawn.20211122221535.log

6e6fad4b76 SMB: switch IPA domain controller role
As a part of CVE-2020-25717 mitigations, Samba now assumes 'CLASSIC
PRIMARY DOMAIN CONTROLLER' server role does not support Kerberos
operations.  This is the role that IPA domain controller was using for
its hybrid NT4/AD-like operation.

Instead, 'IPA PRIMARY DOMAIN CONTROLLER' server role was introduced in
Samba. Switch to this role for new installations and during the upgrade
of servers running ADTRUST role.

93126e01a5 krb5: Pin kpasswd server to a primary one
There are time gaps in which kinit requests may fail due to
offlined SSSD's locator and replication delays.

Since `IPA` provider or SSSD offline the locator plugin for libkrb5
(man 8 sssd_krb5_locator_plugin) can do nothing about this and kinit
fallbacks to the standard libkrb5 algorithm described in `man 5 krb5.conf`.
`krb5.conf` on IPA server doesn't include `kpasswd_server` and kinit
fallbacks to DNS way. DNS (URI or SRV) RRs don't preserve any order
and kinit may contact either master or replica kpasswd servers.
This may result in a password was changed on a replica but was not
replicated to master:
master(kinit)->master(initial)->replica(kpasswd)->master(can't
obtain initial creds with new password)

So, `kpasswd_server` serves as fallback for the offlined locator.

Note: primary_kdc(the former master_kdc) doesn't help here because
it is only used if the initial credentials obtaining fails (see
`krb5_get_init_creds_password` in libkrb5) and not a password change.

02e19d0a39 Add SHA384withRSA as a certificate signing algorithm
It required support in dogtag which was added in 10.5.0.

This is only easily configurable during installation because
it will set ca.signing.defaultSigningAlgorithm to the
selected algorithm in CS.cfg

The certificate profiles will generally by default set
default.params.signingAlg=- which means use the CA default.

So while an existing installation will technically allow
SHA384withRSA it will require profile changes and/or
changing the defaultSigningAlgorithm in CS.cfg and
restarting (completely untested). And that won't affect
already issued-certificates.

New self-service permission to add subids.

New command user-auto-subid to auto-assign subid

The code hard-codes counts to 65536, sets subgid equal to subuid, and
does not allow removal of subids. There is also a hack that emulates a
DNA plugin with step interval 65536 for testing.

Work around problem with older SSSD clients that fail with unknown

0ebc59c26d gssproxy: Don't refresh expired delegated credentials
`mod_auth_gssapi` exports delegated credentials into `/run/ipa/ccaches`
and pass down that path as `KRB5CCNAME` env variable to WSGI worker.

GSSProxy in turn, protects these credentials from direct usage of
`ipa-api`. But the configuration of `service/ipa-api` (in particular,
'cred_store = client_keytab:/var/lib/ipa/gssproxy/http.keytab') and
default GSS name ('=None') dictates to refresh expired credentials
with the client's keytab overwriting the origin credentials with
initial credentials of keytab's principal.

d2d487bccc Set the ACME baseURL in order to pin a client to a single IPA server
ACME uses nonce values to prevent replay attacks. Since the
ipa-ca name can go to any of the IPA servers in order to verify the
nonce the servers need to know the value that was set which
relies on replication. Sometimes the client is faster than
replication so a request can fail.

This change returns the baseURL to the client as the name of the
ACME server during discovery which should pin all requests to this
one IPA server and alleviate the replication issue.

38a86e3367 systemd: enforce en_US.UTF-8 locale in systemd units
Python code does detection of the system encoding based on the locale
settings. On RHEL 8.4 development images we somehow get LANG=en_US which
defaults to iso8859-1 _inside_ the systemd-started service, even though
the whole environment defaults to LANG=en_US.UTF-8.

When instrumented with ExecStartPre=/usr/bin/locale, the following
output can be seen:

locale[45481]: LANG=en_US
locale[45481]: LC_CTYPE="en_US"
locale[45481]: LC_NUMERIC="en_US"

Set the environment to explicit LC_ALL=C.UTF-8 to please the Python
code. FreeIPA server side only cares about actual encoding, not the
language itself. We already use LC_ALL=C.UTF-8 in httpd service snippet.

ee7dfc3d29 Allow mod_auth_gssapi to create and access ccaches in /run/ipa/ccaches
With commit c6644b8566 we default to
create unique credential caches in /run/ipa/ccaches for every client
that connects to IPA with a new session. On F34, mod_auth_gssapi process
running as 'apache' cannot create the ccache in /run/ipa/ccaches because
it has no access rights.

The core of the problem is that we have two different paths to obtaining
a ccache: one where 'apache' running httpd process creates it directly
and one where an internal redirect from 'ipaapi' running httpd process
is happening.

Use SUID and SGID to 'ipaapi'/'ipaapi' and allow 'apache' group to write
to '/run/ipa/ccaches'. This fixes the problem.

Note that we cannot completely remove 'GssapiDelegCcachePerms'. If we'd
do so, mod_auth_gssapi will do redirects and fail.

c0d55ce6de Centralize enable/disable of the ACME service
The initial implementation of ACME in dogtag and IPA required
that ACME be manually enabled on each CA.

dogtag added a REST API that can be access directly or through
the `pki acme` CLI tool to enable or disable the service.

It also abstracted the database connection and introduced the
concept of a realm which defines the DIT for ACME users and
groups, the URL and the identity. This is configured in realm.conf.

A new group was created, Enterprise ACME Administrators, that
controls the users allowed to modify ACME configuration.

The IPA RA is added to this group for the ipa-acme-manage tool
to authenticate to the API to enable/disable ACME.

For now Debian, Fedora, RHEL, etc. build BIND with 'native PKCS11'
support. Till recently, that was the strict requirement of DNSSEC.
The problem is that this restricts cross-platform features of FreeIPA.

With the help of libp11, which provides `pkcs11` engine plugin for
the OpenSSL library for accessing PKCS11 modules in a semi-
transparent way, FreeIPA could utilize OpenSSL version of BIND.

BIND in turn provides ability to specify the OpenSSL engine on the
command line of `named` and all the BIND `dnssec-*` tools by using
the `-E engine_name`.

00a84464ea acme: configure engine.conf and disable by default
When deploying ACME set up configsources.conf to retrieve engine
configuration from engine.conf.  In the initial configuration, the
ACME service is disabled (i.e. it will refuse to service requests).

A subsequent commit will add command(s) for flipping the ACME
service on or off (on a per-server basis).  Later we will move to
LDAP configuration so that management of the ACME service is
deployment-wide.

The default configuration also disables issuance of wildcard
certificates.

3c8352f9a7 acme: add certificate profile
Add a default certificate profile to be used with the ACME service.

The profile requires the (Dogtag) user interacting with the CA to be
a member of the (Dogtag) "ACME Agents" group.  For each CA server we
create a dedicated ACME agent account, make it a member of this
group, and configure the ACME issuer component to use that account.

dd301a4535 acme: set up ACME service when configuring CA
When configuring the CA, create, configure and deploy the PKI ACME
service instance.  This includes creation (if necessary) of the LDAP
container object heirarchy in which ACME-related objects will be
stored.

Dogtag ACME RA account management will be added in a subsequent
commit, removing the use of the 'uid=admin' account (which as of
this commit just has a bogus password).

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.

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.
