Hello,
After update to 4.7.4 on my DC's I see some strange, non-critical (I think)
though behaviour.
I've noticed that:
sometimes running command
wbinfo -u
doesn't list any of the users, in log i see this:
*../source3/rpc_client/cli_pipe.c:568(cli_pipe_validate_current_pdu)*
*../source3/rpc_client/cli_pipe.c:568: RPC fault code
DCERPC_NCA_S_PROTO_ERROR received from host dc3!*
*../source3/winbindd/winbindd_rpc.c:403(rpc_rids_to_names)*
*rids_to_names: failed to lookup sids: NT_STATUS_RPC_PROTOCOL_ERROR*
runnign wbinfo -g works fine
samba-tool user list works fine
converting via wbinfo sid to uid, or uid to sid, or sid to name works
fine even when error as above occurs.
after restarting samba, wbinfo -u works fine for random period of time.
When error as above occurs AD DC works fine (i think), that is: users are
able to authenticate, and I see in logs, that "sid-to-name" are resolved
correctly.

One thing that slightly bothers me is that sometimes users take seemingly
longer to authenticate and there are problems with GPO processing, for
example when I run on windows client "gpudpate" i get random errors that
policy XYZ couldn't be processed. When i run "getfacl" on said policy, and
check ACL form windows perspective I see absolutely nothing out of order
(no difference between other policies that are processed without issue) I
have no idea if this is at all connected, or is it connected with my
different question.
Comments/help appreciated
Regards,
Kacper
