You don't mention which OS you are running, but it seems
that you must be running Solaris 8 or Solaris 9.    I would guess
that you probably installed the SEAM packages for Solaris.

The likely problem is that Solaris 8 and 9 do not have support for the
same encryption types as the newer MIT Kerberos code.  If the
server (MIT) is issuing keys that the client (Solaris) cannot understand,
the client library will not be able to do anything with the tickets.

Send output of "klist -ef" to show the enctypes used in your
client's ticket cache, if they show up as numbers (ex:  "enctype 17 ...")
instead of names ("AES-128 ..."), then this is definitely the problem.
If your cache already has only DES keys, then there must be something
else wrong.

Solaris 10 has support for all of the enctypes that MIT supports.
