[Samba] Issues with Samba 3.0.2 on OSX using ADS.

[Huyler, Christopher M]

We have a Win2K network at work and I've been trying to integrate my Mac
10.3 machine into the network.  It seems that once one thing is working,
something else is not. I have read through various Mac tutorials found
on the web but none seem to solve my problem.

Right now I have Active Directory Domain Logons working successfully but
Samba will not allow anyone (from Mac/Unix/Windows) to connect. I keep
getting the following entries in the /var/log/samba/log.smbd log:

[2004/04/23 15:07:03, 0]
/SourceCache/samba/samba-56/samba/source/smbd/server.c:main(747)
  smbd version 3.0.2 started.

erberos(173)
  Failed to verify incoming ticket!

I can't figure it out.  I'm positive that Kerberos is configured
correctly because I can run kinit and klist successfully and I can log
in using my domain account.  Here is some more info:

 [root at usfrosx1 root]# net ads leave -S usildc03 -U huych02%xxxxxxxx
Removed 'USFROSX1' from realm 'CA.COM'

[root at usfrosx1 root]# net ads testjoin -S usildc03 -U huych02%xxxxxxxx

[root at usfrosx1 root]# net ads testjoin -S usildc03 -U huych02%xxxxxxxx
Join is OK

After all that, I still get the reply_spnego_kerberos(173) errors.  Any
help would be appreciated, I have searched the net up and down and
nothing seems to help.  Below is a copy of my smb.conf file for
reference:
