I upgraded a couple of systems to Samba 3.0 GA from rc4, and ran into the following. Before the upgrade, I was able to check the secret as follows: kehall@lnxsmb3t:/var/log> wbinfo -t checking the trust secret via RPC calls succeeded But after, I get this: lnxsmb3t:/etc/logrotate.d # wbinfo -t checking the trust secret via RPC calls failed error code was (0x0) Could not check secret Winbindd also complains about the "realm" parm in smb.conf, but it appears it's done this all along. Everything else seems to work.
