Would you look at that! All 'query' backends (ldap, mysql, pgsql) has
primaryGroupSid in their Samba user databases and this is enough to have
the requested optimization.
The attached patch introduces yet another pdb interface method
enum_group_prmembers to retrieve SIDs of users with the given
primaryGroupSid. Its default implementation goes through all users as it
was done in get_memberuids(). Implementations in ldap, mysql, and pgsql
backends use correct filter and query.
get_memberuids() is adjusted to use this new method instead of going
through all users all the time.
This patch is made on top of my previous patch.
I've tested it a little - group members are shown correctly and smbd
Hope you like it. Note, no "ldap trust ids" is necessary. :o)
