Credentials cache server unavailable

[Jiva DeVoe]

I have a daemon which I am trying to port to Mac OS X.  It uses the  
GSS Api with Kerberos to do authentication.  I have it booting as  
part of the SystemStarter scripts at boot time... but when it does,  
and as part of this, it calls kinit (using a keytab) to set up the  
initial principals.  However, I get this error message:

kinit: Error getting initial tickets: Credentials cache server  
unavailable

Anyone know how I can fix this?

The script works fine if I run it after the machine is booted up and  
in a terminal.
