Mounting via the Finder works and uses kerberos.
Mounting via terminal – mount_smbfs //user@server/share – asks for credentials. doesn’t use Keberos.
AFP automount work. (with ExtremeZ-IP)
Mac OS X 10.6 clients work

Server is Windows 2008
Service principle names (SPN) were added for cifs/shortname and cifs/FQDN – checked ADSI edit MMC and it shows the all of the expected SPNs.
There is a set of SPNs called “restrictedkrbhost” for both short and long name. – I dont’ know what those are. I removed them and it didn’t help.

I saw this post: https://www.afp548.com/forum/viewtopic.php?showtopic=23694 but it after checking/adding the cifs SPNs I still have the issue.

Any suggestions on getting 10.5.8 kerberos working with SMB/autofs?

Thanks,
