    passdb: Cache output from pdb_[ug]id_to_sid
    
    A customer complained that after upgrading to Samba 4.0 fileserver
    its LDAP server was flooded with uid2sid and gid2sid request for id
    0. With 4.0 we do a lot more user-space ACL checking which involves
    uid2sid/gid2sid. This caches the corresponding results.
