[K12OSN] Bad magic on Winbind authentication

[sonjag at comcast.net]

I am running Ubuntu with LTSP authenticating to ADS on a Windows 2003 server SP1. My windows side of the network is running fine. The Linux terminals are not able to login all users... weirdly, some can, some can't. In my log.winbindd-idmap file, I get a slew of entries similar to this:

[2006/09/25 22:54:21, 0] tdb/tdbutil.c:tdb_log(772)
  tdb(/var/lib/samba/winbindd_idmap.tdb): rec_free_read bad magic 0x42424242 at offset=17476

I have tried to add a user to the Linux machine and the new Linux users can't login either. I'm not sure if they should-- maybe Linux can only see its admin and ADS users. 

wbinfo -u gives me a list of all of my users, including those who can and can't login.

Solutions I've seen around are deleting files in /var/lib/samba and restarting Winbind. Tried that, still not working. Any suggestions?


Thanks!
