As Johan noted, AFS uses Kerberos.
The problem isn't that AFS uses Kerberos, the problem is that it extends
the concept of ucred to include in-kernel Kerberos credentials. It does
that so that the file system can use said Kerberos credentials when
talking to the file server(s).
Setting up that in-kernerl Kerberos cache requires a system call (or more,
I'm not familiar with the exact innards of it).
