I am trying out the new version of PAM (0.99.7) from experimental. Ever
since I upgraded libpam-modules and libpam-runtime, I have been unable
to unlock the screen once it was locked by gnome-screensaver.

Although this happened immediately after upgrading, I also tried logging
out and logging in again, but I still can't unlock the screen once the
screensaver activates.

The following messages are written to syslog:

Aug 12 23:34:08 xerces unix_chkpwd[14516]: check pass; user unknown
Aug 12 23:34:08 xerces unix_chkpwd[14516]: password check failed for user (sam)
Aug 12 23:34:08 xerces gnome-screensaver-dialog: pam_unix(gnome-screensaver:auth): authentication failure; logname= uid=1000 euid=1000 tty=:0.0 ruser= rhost=  user=sam

I'm not using anything fancy like LDAP or Kerberos, and I haven't customised
/etc/pam.d/gnome-screensaver; it simply includes the common-auth file which
I have also not touched.
