Hi Jonathan,

network.negotiate... is set correctly
I'm also sure it has nothing to do with the the principal that  
authed,  as that is running on a different client. The problem occurs  
only at that client on Mac OS 10.4.

Your "ignorance on Mac clients" might be correct on some features. As  
e.g. the SSL keys must be stored in the keychain and can't be accepted  
by iCal itself. But in that case I'm using sunbird as a client.
And I guess if I am not able to connect through my browser to the  
authed areas of the server server then something different than a  
wrong client calendar configuration is happening. Are there  
differences in the Kerberos-Tools of Mac OS 10.4 and 10.5?
