I'm running Winbind 3.0.33 with FreeRadius for windows authentication. Has anyone found a solution to these error messages in the samba.log? [root@pr01 log]# tail samba.log [2009/03/12 09:28:33, 0] lib/util_sid.c:string_to_sid(242) string_to_sid: Sid S-0-0 is not in a valid format.

[2009/03/12 09:38:35, 0] lib/util_sid.c:string_to_sid(242) string_to_sid: Sid S-0-0 is not in a valid format. I get several a minute. I've found many posts with the same complaint, but no solution. Is upgrading (or downgrading) likely to stop it? It seems to be a purely cosmetic issue, but I'd still like to find a solution. winbindd version 3.0.33-3.7.el5 (RH5 RPM) RedHat Linux 5, release 2 fully patched -Mike _________________________________________ Mike Diggins Voice: 905.525.9140 Ext. 27471 Network Analyst, Enterprise Networks FAX: 905.522.0511 University Technology Services E-Mail: mike.diggins@mcmaster.ca McMaster University, Hamilton, Ontario
