find set of patches to add support to enumerate UPN suffixes
associated with a forest smbd is serving.
This is needed for the cases like FreeIPA cross-realm forest trusts where
additional DNS domains may be associated with the realm. The patchset
exposes additional DNS domains to a requester (AD DC) via
netr_GetForestTrustInformation and netr_DsRGetForestTrustInformation. In
the latter case this is done only for a condition when trusted_domain_name
is NULL, as described in MS-NRPC and in source4/torture/rpc/netlogon.c.
FreeIPA's implementation for pdb_enum_upn_suffixes() is here:
Here is a screenshot of how it looks like from a Windows Server 2012 side:
Note that suffixes are disabled by default when imported, this is normal
In order to implement same for Samba AD DC code we would need to define
some schema and tree location to store the suffixes. In FreeIPA case we use
domainRelatedObject object class and associatedDomain attribute to store
list of domains. These are standard LDAP object class and attribute and
they could be reused.
Same applies to ldapsam module, we need to define where and how store the
Currently source4/torture/rpc/forest_trust.c expects in
test_validate_trust() that only primary domain's DNS name is returned by
netr_GetForestTrustInformation(). This will need to change when support for
UPN suffixes is added in Samba AD DC code.
pdb_set_upn_suffixes() was added from a perspective of making possible to
modify the suffixes from 'net' utility.
