I'm stumped. Just started working with an MIT KDC v5 1.3.1 running on Linux and trying to get the IBM sample apps (GSSClient and GSSServer) working. The apps are here: http://www-106.ibm.com/developerworks/java/library/j-gss-sso/
I have two principals set up using defaults: one for the client and one for the server. The GSSClient, GSSServer and KDC are all running on the same machine in the same Realm.
I start the server just fine and it waits with:
GSSServer starts... Waiting for incoming connection
When I run the client the client authentictes and the context is successsfully created. However, the GSSServer throws an Exception:
GSSException: Failure unspecified at GSS-API level (Mechanism level: KDC has no support for encryption type (14))

The client also throws an Exception:
GSSClient... Getting client credentials
GSSClient... GSSManager creating security context
GSSClient...Sending token to server over secure context
GSSClient...Secure context initialized
GSSClient...Written 511 bytes

Client authentication denied...
This happens consistently and I cannot get passed this point! The weird thing is, is that the same thing happens using the Windows 2003 Server KDC! Same Exception.
Can anyone help me understand what is causing this? The Exception mentions "KDC has no support for encryption type (14)" but we're not specifying any encryption type other than the defaults. The principals are the same as far as I know.
Thanks.
