Problems wirh Kerberos Auth

[Friede, Tobias]

Hi,

 

I have a problem with Single Sign on based on mod_kerb_auth and Krb5. 

I generated a keytab for my apache2 Webserver. But if I want to Authentificate via Kerberos the following error message is shown in the apache log.

 

[Fri Jun 17 11:19:20 2011] [error] [client XXX ] failed to verify krb5 credentials: Message size is incompatible with encryption type

 

Can anybody tell me what I can do? 

 

I have a Fedora Core 15 System with the paket krb5-workstation-1.9.7.fc15.

 

 

Gruß

Tobias
