Old story - I've seen it dozens of times.
<br />
<br />Its the same story with the authentication subsystem broken - probably because someone tried to hack in. It happens everytime there is a strong hacking attempt on the BlueQuartz machines. It breaks something between the network services that require authentication and the actual authentication subsystem. They're both still running - but won't play together.
<br />
<br />Use this script to fix it:
<br />
<br />#!/bin/bash
<br />/sbin/service sendmail stop
<br />/usr/bin/killall -9 sendmail
<br />/sbin/service spamassassin stop
<br />/sbin/service dovecot stop
<br />/usr/bin/killall -9 pop3-login
<br />/usr/bin/killall -9 dovecot-auth
<br />/sbin/service dbrecover stop
<br />/sbin/service auditd stop
<br />rm -f /var/db/log*
<br />/sbin/service auditd start
<br />/sbin/service dbrecover start
<br />/sbin/service saslauthd restart
<br />/sbin/service dovecot start
<br />/sbin/service spamassassin start
<br />/sbin/service sendmail start
<br />
<br />The only difference, if you've got some of the Nuonce packages installed - I add a line to also kill all MailScanner processes. As you can see - that script will stop all services that need network authentication (except SSH). It then restarts the authentication subsystems. And finally - it restarts the network services. I've saved that script in a directory under /root called /root/bin and named it fix-server. That way, I can log in (only as admin and then "su -" to root) and run it when some scumbag tries to hack one of my servers.
<br />
<br />Just remember - it has to be run as "root". Even running as "admin" won't work - only root can do all those things. But it will fix a broken BQ every time its been hacked at. But if you're still having any problems - reboot!
<br />
<br />Good luck.
<br />
<br />

Subject: [BlueOnyx:01438] Password failure
<br />
<br />> <font face="Arial" size="2">Hi. Users credentials on a Blue Quartz (sorry
if
this is the wrong forum) fails. When you log in on the GUI it says You have not
entered a correct username etc. The admin one works and if I try and change the
password within the virtual site, although there are no errors, it still won't
log in. POP3 for that user then fails
etc.</font>
<br />>
<br />> <font face="Arial" size="2">Is there a fix for this at
all.</font>
<br />>
<br />> <font face="Arial" size="2">Thanks</font>
