If trusted domain object (TDO) is lacking ipaAllowedToPerform;read_keys
attribute values, it cannot be used by SSSD to retrieve TDO keys and the
whole communication with Active Directory domain controllers will not be
possible.
This seems to affect trusts which were created before
ipaAllowedToPerform;read_keys permission granting was introduced
(FreeIPA 4.2). Add back the default setting for the permissions which
grants access to trust agents and trust admins.

During an investigation into filter optimisation in 389DS it was
discovered that two attributes of the certmap query are unindexed.
Due to the nature of LDAP filters, if any member of an OR query is
unindexed, the entire OR becomes unindexed.
This is then basically a full-table scan, which applies the filter test
to the contained members.

Active Directory schema includes altSecurityIdentities attribute
which presents alternative security identities for a bindable object in
Active Directory.
FreeIPA doesn't currently use this attribute. However, SSSD certmap
library may generate searches referencing the attribute if it is
specified in the certificate mapping rule. Such search might be
considered unindexed in 389-ds.
Define altSecurityIdentities attribute to allow specifying indexing

A previous refactoring of SELinux tests has have a wrong

Actually, '.ldif' and '.update' files are passed through
Python template string substitution:
> $$ is an escape; it is replaced with a single $.
> $identifier names a substitution placeholder matching

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.

With system-wide crypto policy in use, arcfour-hmac encryption type
might be removed from the list of permitted encryption types in the MIT
Kerberos library. Applications aren't prevented to use the arcfour-hmac
enctype if they operate on it directly.
Since FreeIPA supported and default encryption types stored in LDAP, on
the server side we don't directly use a set of permitted encryption
types provided by the MIT Kerberos library. However, this set will be
trimmed to disallow arcfour-hmac and other weaker types by default.
While the arcfour-hmac key can be generated and retrieved, MIT Kerberos
library will still not allow its use in Kerberos protocol if it is not
on the list of permitted encryption types. We only need this workaround
to allow setting up arcfour-hmac key for SMB services where arcfour-hmac
key is used to validate communication between a domain member and its
domain controller. Without this fix it will not be possible to request
setting up a machine account credential from the domain member side. The
latter is needed for Samba running on IPA client.
Thus, extend filtering facilities in ipa-pwd-extop plugin to explicitly
