Kerberos only handles authentication. You need something for
authorization. By default, the kerberos libraries will match principals
in the local default realm to local users. (principal == local user
name.) [EMAIL PROTECTED] can login as cclausen.
[EMAIL PROTECTED] cannot login without authorization.

Setting up a trust does NOT automatically grant authorization for the
foreign realm. Try creating a ~/.k5login file in the home directory of
the user you are logging in as listing authorized Kerberos principals,
one per line.

For instance:
C:\>klist
Ticket cache: API:[EMAIL PROTECTED]
Default principal: [EMAIL PROTECTED]
Valid starting Expires Service principal
05/03/07 20:26:36 05/04/07 06:26:36 krbtgt/[EMAIL PROTECTED]
C:\>putty ial.illigal.uiuc.edu
C:\>klist
Ticket cache: API:[EMAIL PROTECTED]
Default principal: [EMAIL PROTECTED]
Valid starting Expires Service principal
05/03/07 20:26:36 05/04/07 06:26:36 krbtgt/[EMAIL PROTECTED]
05/03/07 20:26:36 05/04/07 06:26:36
krbtgt/[EMAIL PROTECTED]
05/03/07 20:26:58 05/04/07 06:26:36
host/[EMAIL PROTECTED]
On the remote system:
[EMAIL PROTECTED]:~$ cat .k5login
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]:~$ klist
Ticket cache: FILE:/tmp/krb5cc_1000_L30429
Default principal: [EMAIL PROTECTED]
Valid starting Expires Service principal
05/03/07 20:26:58 05/04/07 06:26:36 krbtgt/[EMAIL PROTECTED]
[EMAIL PROTECTED]:~$ cat /etc/krb5.conf | grep default
[libdefaults]
default_realm = ILLIGAL.UIUC.EDU
