Authentication problems using Telnet on Solaris 9

[Bill Smith]

I'm trying to authenticate to our W2K domain controllers from my UNIX box 
running Sun's kerberos distribution (SEAM) on a Solaris 9 box.  When I try 
lo login using my domain logon, I get the following error

authentication failed:  Unknown code 2

in /var/adm/messages the following message is also logged

Sep  3 13:38:03 smithwe1-unix login: [ID 537602 auth.error] PAM-KRB5 (auth): 
krb5_verify_init_creds failed: Unknown code 2

I've done some searching and found some info indicating possible problems 
like this on Solaris 9 but so far no resolution.

FWIW, when I run kinit, I can authenticate to the domain controllers with no 
problems.

Any idea on what the problem(s) may be?

Thanks,

Bill
