AES-128-CBC was recently enabled as default wrapping algorithm for transport of secrets.
This change was done in favor of FIPS as crypto-policies disabled 3DES in RHEL9, but
setting AES as default ended-up breaking backwards compatibility with older RHEL systems.
This commit is tuning some defaults so that interoperability with older RHEL systems
works again. The new logic reflects:
- when an old client is calling a new server, it doesn't send any value for wrapping_algo
and the old value is used (3DES), so that the client can decrypt using 3DES.
- when a new client is calling a new server, it sends wrapping_algo = AES128_CBC
- when a new client is calling an old server, it doesn't send any value and the default is
to use 3DES.
Finally, as this logic is able to handle overlapping wrapping algorithm between server and
client, the Option "--wrapping-algo" is hidden from "ipa vault-archive --help" and "ipa
vault-retrieve --help" commands.

Add support for bind grace limiting per
https://datatracker.ietf.org/doc/html/draft-behera-ldap-password-policy-06
389-ds provides for alternative naming than the draft, using those
instead: passwordGraceUserTime for pwdGraceUserTime and
passwordGraceLimit for pwdGraceLoginLimit.
passwordGraceLimit is a policy variable that an administrator
sets to determine the maximum number of LDAP binds allowed when
a password is marked as expired. This is suported for both the
global and per-group password policies.
passwordGraceUserTime is a count per-user of the number of binds.
When the passwordGraceUserTime exceeds the passwordGraceLimit then
all subsequent binds will be denied and an administrator will need
to reset the user password.
If passwordGraceLimit is less than 0 then grace limiting is disabled
and unlimited binds are allowed.
Grace login limitations only apply to entries with the objectclass
posixAccount or simplesecurityobject in order to limit this to
IPA users and system accounts.
Some basic support for the LDAP ppolicy control is enabled such that
if the ppolicy control is in the bind request then the number of
remaining grace binds will be returned with the request.
The passwordGraceUserTime attribute is reset to 0 upon a password
reset.
user-status has been extended to display the number of grace binds
which is stored centrally and not per-server.
Note that passwordGraceUserTime is an operational attribute.

Add new options to ipa config-mod, allowing to enable
SID generation on upgraded servers:
ipa config-mod --enable-sid --add-sids --netbios-name NAME
The new option uses Dbus to launch an oddjob command,
org.freeipa.server.config-enable-sid
that runs the installation steps related to SID generation.
--add-sids is optional and triggers the sid generation task that
populates SID for existing users / groups.
--netbios-name is optional and allows to specify the NetBIOS Name.
When not provided, the NetBIOS name is generated based on the leading
component of the DNS domain name.
This command can be run multiple times.

New LDAP object class "ipaUserSubordinate" with four new fields:
- ipasubuidnumber / ipasubuidcount
- ipasubgidnumber / ipasgbuidcount
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.

Second part of adding support to manage IPA as a user from a trusted
Active Directory forest.
Treat user ID overrides as members of groups and roles.
For example, adding an Active Directory user ID override as a member of
'admins' group would make it equivalent to built-in FreeIPA 'admin'
user.
We already support self-service operations by Active Directory users if
their user ID override does exist. When Active Directory user
authenticates with GSSAPI against the FreeIPA LDAP server, its Kerberos
principal is automatically mapped to the user's ID override in the
Default Trust View. LDAP server's access control plugin uses membership
information of the corresponding LDAP entry to decide how access can be
allowed.
With the change, users from trusted Active Directory forests can
manage FreeIPA resources if the groups are part of appropriate roles or
their ID overrides are members of the roles themselves.

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).

SMB service has a number of predefined properties that must be set at a
creation time. Thus, we provide a special command that handles all the
needed changes. In addition, since SMB principal name is predefined, it
is generated automatically based on the machine hostname.
Since we generate the service's object primary key, its argument/option
should be removed from the list of the command's arguments and options.
We also remove those options that make no sense in the context of SMB
service.
Most controversial would probably be a lack of the authentication
indicator that could be associated with the service. However, this is
intended: SMB service on the domain member is used by both humans and
other SMB services in the domain. Thus, it is not possible to require a
specific authentication indicator to be present: automated acquisition
of the credentials by a domain controller or other domain member machine
accounts is based on a single factor creds and cannot be changed.
Access to SMB service should be regulated on the SMB protocol level,
with access controls in share ACLs.
