Unable to Communicate with the Server - Jabber 9.7 and CUCM /IMP 10

Hey Guys,


I have a frustrating problem with Jabber. I have configured a new CUCM 10 and IMP environment, all looks good, with no system errors. I also configured a very basic jabber-conf file which basically just states to use UDS as the Directory source.

Have configured a CSF device in CUCM and associated to an enduser. Then applied the Jabber service profile. UNder the assigned Users page, I can see my user is assigned.

I'm working with an internal and external domain name. (.local and .com)

So I created my _cisco-uds SRV record and _cuplogin SRV record for pointing to A record cucm.lab.local. I have a dns server with two zones configured.

My laptop is not associated to any Windows Domain.

My configured IM presence domain is and Im using USERID@defaultdomain.  Under Domains in IMP I can see the is present.

I have restarted all necessary services on IMP.

I then install Jabber 9.7 on my Win7 laptop.

I run a packet trace and try to login into Jabber. Now I see the SRV request and response for cisco-uds is fine.. I then see communication flow between the laptop and CUCM server fine.. I get prompted to validate the CUCM cert (self signed). Click ok to proceed, then I see my laptop starting to talk with the IM&P server, then am prompted to validate the IMP server cert (again self seigned). Click ok to proceed. The I receive the "cannot communicate with the server" error.


I turn to my CSF Log files and see an Authentication error 15 in the log:

IMPStackCap::Login::OnLoginError] - OnLoginError: (data=0) LERR_JABBER_AUTH <15>: Authentication error with server e.g. resource bind, TLS, create session or SASL error

This is where I get too..

Some further settings that you may want to know

service parameters:

CUCM Domain is lab.local

SRV Cluster: presence.lab.local



Directory URI is

IM Address is


LDAP Authentication is enabled.


Jabber Login:


Any suggestions or assistance is much appreciated.

Also if you could advise on how to trace Jabber Logon event in RTMT that would be helpful

LERR_JABBER_AUTH <17> in your

LERR_JABBER_AUTH <17> in your jabber.log can also indicate that you have an invalid URI scheme.  If you do advanced settings in IM&P and create an invalid URI in AD for the mail, although it will push it won't allow you to log in.  You can only see this using the troubleshooter.
