any non-krb5int way to pass a keyblock to get_init_creds?

[Chris Hecker]

It seems there's no exposed way to call krb5_get_init_creds with a key 
directly.  If I've got a key that's not stored in a keytab (like it got 
handed to me some other way), it looks like the best/only way to do this 
is to create a MEMORY keytab, manually create a keytab_entry, add the 
entry, and then pass that to get_init_creds_keytab?

Sound right?

Thanks,
Chris
