Hi Andrew

Yes. I realize that we make too much noise here. Sorry.

And yes, we really should dust off our copies of K&R.

Also -1 for not following up:
We could not unlock the screensaver under a s4 linux session so we used 
Yast to add krb5 auth. This created a new krb5.conf which also failed to 
unlock the screensaver:-( We replaced it with the 4 liner from the 
provision and samba-tool worked again.

Just for the record, this must be a openSUSE/pam issue as 
gnome-screensaver on Ubuntu unlocks fine. There is a discussion on both 
openSUSE and mit lists about this.
