KRB5 error code 52

[Tyson Oswald]

Kerberos experts,
 
I am using SEAM 1.01 on Solaris 9 and am authenticating to AD.  When others try they fail the login with the "KRB5 error code 52" error.  I read that this has something to do with UDP packet size and to try TCP.  Is there a way in SEAM to have it use TCP rather then UDP, or to try UDP then TCP is that fails?  I was hoping there was a configuration parameter in krb5.conf.
 
thanks,
Tyson Oswald
