After looking through the pam.d files I realized the various pop3, sshd
etc files had reverted back to a non PWDB form.  I copied a working one
over I am installing from the ISO on another server to compare.  The
only thing I can think of is an update via yum happened, but the
/var/log/yum.log stops at 9/18/04.

I currently have for sshd, cced and pop3, which appears to work:

auth       required service=system-auth
auth       required
account    required service=system-auth
password   required service=system-auth
session    required service=system-auth
session    required
session    optional

system-auth is:
# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
auth        required      /lib/security/$ISA/
auth        sufficient    /lib/security/$ISA/ likeauth nullok
auth        required      /lib/security/$ISA/

account     required      /lib/security/$ISA/

password    required      /lib/security/$ISA/ retry=3
password    sufficient    /lib/security/$ISA/ nullok
use_authtok md5 shadow
password    required      /lib/security/$ISA/

session     required      /lib/security/$ISA/
session     required      /lib/security/$ISA/

Not sure if this will help anyone out, but this started around 10AM EST.
Cant find anything in the logs that would indicate an upgrade or what

Hmm I assume dv4-utils is actually db4-utils, which I have installed.

Should I download the CVS source tree and install the dbrecover init
script?  It wasn't on the Fedora Core 1 ISO install CD.

For some random odd reason, which I have yet to find, PWDB stopped
working.  I rebooted the server, still had the problem, all services
using PAM (and hence the PWDB files) failed authentication.  I deleted
the last site added, with about 10 users (all with dots in their
usernames like first.lastname) and it started working immediately.

I then restored this site using CMU and authentication continued to

Very bizarre.  I wrote a btree perl script to dump the .db files in
/var/db and all the files dumped out ok, no errors so it doesn't appear
to have been corruption.

I noticed some threads about dbrecover and dv4-utils - are they
available from the website?

I don't have dbrevover and running db_recover just gives an error about
unable to start in the environment.
