## On Server

### Invalid Password - Jabber Daemon

If you see this in `/var/log/rhn/osa-dispatcher.log`

    2011/09/08 17:18:12 -05:00 7402 0.0.0.0: osad/jabber_lib.__init__
    2011/09/08 17:18:13 -05:00 7402 0.0.0.0: osad/jabber_lib.setup_connection('Connected to jabber server', 'spacewalk.example.com')
    2011/09/08 17:18:13 -05:00 7402 0.0.0.0: osad/jabber_lib.register('ERROR', 'Invalid password')

Run this [as a cron job every night](https://www.redhat.com/archives/spacewalk-list/2010-September/msg00078.html) on **the server**:

    /sbin/service jabberd stop
    /sbin/service osa-dispatcher stop
    rm -Rf /var/lib/jabberd/db/*
    /sbin/service jabberd start
    /sbin/service osa-dispatcher start

Run this on **the client**:

    service osad stop
    rm /etc/sysconfig/rhn/osad-auth.conf
    service osad start

### Checking the FQDN quickly

All three commands should return the same thing (host.domain.tld)

    openssl x509 -text -in cat /etc/rhn/rhn.conf | grep osa_ssl_cert | sed 's/.* =//' | grep '^ :space:*Subject:.*CN=' | sed 's/.*CN=//'
    openssl x509 -text -in grep '^ :space:*<id\ .*pemfile="' /etc/jabberd/c2s.xml | sed 's/.*pemfile="\\([^"]*\\) .*/\1/' | grep '^ :space:*Subject:.*CN=' | sed 's/.*CN=\\(.*\\)[\/$].*/\1/'
    grep '^:space:*<id\ .*pemfile="' /etc/jabberd/c2s.xml | sed 's/.*>\\(.*\\).*<.*/\1/'

## On Client

### osad\_client.\_check\_signature: Signatures do not match

> [Most likely you](http://markmail.org/message/nf2hjjlcykzu6uqk#query:+page:1+mid:upgpa2j4sqnpw6z4+state:results) re-ran `rhnreg_ks` to re-register the system to your spacewalk server.
> This broke the association of osad user <> systemid that is stored in the DB.
> Remove the auth file for osad from within /etc/sysconfig/rhn/ on the client and
> restart osad, this will re-generate a new osad auth file and this error should go away.

So:

  service osad stop   rm /etc/sysconfig/rhn/osad-auth.conf   service osad start
