Winbind errors

[Mike Diggins]

Freeradius 2.1.3
winbindd version 3.0.33-3.7.el5
RedHat Linux 5, release 2 fully patched

I know this isn't a FreeRadius issue, but is related. Has anyone running 
FreeRadius with Winbindd for windows authentication, found a solution to 
these error messages in the samba.log?

[root at prad01 log]# tail samba.log

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.
