s3:libsmb/namequery.c: add saf_join_store() function
saf_join_store() should be called after a successful domain join, the affinity to the dc used at join time has a larger ttl, to avoid problems with delayed replication. metze Signed-off-by: Stefan Metzmacher <metze@samba.org> Signed-off-by: Günther Deschner <gd@samba.org> (cherry picked from commit 80e74a27c55c01221091e3eec930c2ac4433c22c)
