Troubleshooting XMPP or CUPS integration

• Unless you have a legimate SSL certificate on your CUPS server
  (not a built in self-signed cert)
  You will need to disable TLS.
  
  CUPS -> System -> Security Settings -> uncheck "Enable XMPP Client to CUP Secure Mode"
• username has to be in the form of cisco-enduser@domainname.com

• Verify DNS records for BOTH server and client.
  You can test using these commands from a DOS prompt
• nslookup
• set q=SRV
• _xmpp-server._tcp.<your internal domain name>
  Example: _xmpp-server._tcp.bridgeoc.com
  There should be Service Location Records for both pointing to the fqdn of the CUPS server, NOT the IP address.
• Create the records using normal DNS tools using these detail.
• _xmpp-server  Port 5269
• _xmpp-client    Port 5222

If using a Microsoft DNS server, the additions will look similar to this.
