gnome-screensaver configures with --disable-pam

[Sean McNeil]

Why???

I remember this was discussed about xscreensaver at one time and was
fixed.  Is there any reason at all why --disable-pam has been set in the
configure for x11/gnome-screensaver?  I took this offensive setting out
and I can once more lock my screen.  Naturally, with it in I get errors
and it fails to lock because I happen to use PAM with LDAP to get
usernames and passwords. Not good.
