Snow Leopard: Kerberos ticket not renewing coming out of Screen Saver

We had another case opened with Apple about Kerberos ticket not renewing after typing in password coming out of screen saver in Snow Leopard. They send me this instruction on modifying a file in /etc and it looks like it is resolving the problem. If you guys have Snow Leopard machine bound to AD. Please try it out too so we can confirm it does work.

Please edit the "“system.login.screensaver” entry in the /etc/authorization file to read like this:

system.login.screensaver

class
rule
comment
(Use SecurityAgent.) The owner or any administrator can unlock the screensaver.
rule
authenticate-session-owner-or-admin


Note that the string:

The owner or any administrator can unlock the screensaver

is changed to:

(Use SecurityAgent.) The owner or any administrator can unlock the screensaver
