[Bug 367878] [NEW] segfault in pam_smbpass.so (reported in syslog)

[Steve Almond]

Public bug reported:

Binary package hint: libpam-mount

Unable to log into Ubuntu 8.10 (server). Unable to log into Courier,
samba, or CUPS' secure pages. Unable to log in via SSH unless I disable
UsePAM in sshd_config. Single-user mode seems to work as expected.
Apache is still serving webpages, and phpMySQLadmin is working. Server
had been up c.75 days before today's reboots, and safe-upgrade'd daily.

Problem appeared to start yesterday, c. 1300 BST, when attempting to
print via CUPS/cancel print job in CUPS from an XP machine. Problem may
have been dormant for some time, but is now making my web/mail/file-
server (almost) unuseable.

Boot appears normal (to me, anyway!). Ubuntu prints server version,
name, etc, and prompts for username and password as usual. Entering
username and password appears to work as usual, but the server version,
etc reappear and server prompts for username again.
