I'm testing out a new Samba setup to hopefully replace my aging Win2k
domain. I've got some of it working:
- My PDC (shadow) seems to be working on the CASA domain with an LDAP
- nss_ldap and pam_ldap are working on shadow
- I can run wbinfo -u and get the user info from LDAP on shadow.
- I can run wbinfo -a username%password and authenticate a user on shadow.
I can run getent passwd and getent group and see the local users/groups as
well as the ones in the ldap directory but if I change /etc/nsswitch.conf
to only use winbind for passwd, I get nothing.
I see the following message in all of the winbind logs
[2009/03/29 09:03:26, 1]
cli_pipe_validate_current_pdu: RPC fault code DCERPC_FAULT_OP_RNG_ERROR
received from remote machine SHADOW pipe \lsarpc fnum 0x71a5!
this message appears over and over in log.winbindd
[2009/03/29 21:46:00, 2] winbindd/winbindd.c:remove_client(761)
final write to client failed: Broken pipe
Are either of those messages familiar to anyone? Are they something I need
to follow up on? Are they an indicator of something I don't have
I'm learning a lot in the process, but I'm kind of running out of ideas for
what I need to do to get winbind to work on the PDC. I'm also seeing the
same set of errors from every client I've built also. I used the same
smb.conf with localhost changed to shadow.casa.local and the security
changed from user to domain.
If anyone can let me know what I don't have configured correctly please let
