[Samba] winbind problems

[Brian Kesting]

I have tried using a + separator with no success.  I also get this in my log.winbindd file as soon as I restart winbind:

[2004/12/20 17:33:27, 1] libsmb/clikrb5.c:ads_krb5_mk_req(313)
  krb5_cc_get_principal failed (No such file or directory)

I have nsswitch.conf, krb5.conf configured and winbind seems to be running properly for the most part.  With wbinfo I can get all of my user and group information.  Problem is, it seems that at random times, the samba server just stops authenticating the windows user names and accounts.  If I restart the winbind or smb service, then all seems to be well again for a while.  Right now the only way I can keep this running is to run a cron job that restartes the samba and winbind services every hour.  This is really bugging me as I cannot figure out what is going on.  Can anyone help me?  I have included some of my configuration and log files below.  Thanks in advance.

The separator might be a problem.
