Add PAC to master host TGTs
For a proper SASL bind with GSSAPI against an AD LDAP server a PAC is
needed. To allow SSSD in ipa_server_mode to access the LDAP or GC server
of a trusted domain with the credentials of a FreeIPA server host a
PAC must be added to the TGT for the host.
We use the well know RID of the Domain Computers group (515) for the
primary gid element of the PAC, this is the same as AD uses for host
tickets. The rid element of the PAC is set to the well know RID of the
Domain Controllers group (516). This is working for the SSSD use case
but might be improved later for more general use cases.
To determine if a host is a FreeIPA server or not it is checked if there
is an entry for the host in cn=master,cn=ipa,cn=etc,$base. Unfortunately
this requires an additional LDAP lookup. But since TGS-REQs for hosts
should be rare I think it is acceptable for the time being.
