CUPS 6.0.6 and CUPC 7.0.x DeskPhone Mode not working

Hi Everyone,

we got a Problem when enabling DeskPhone in the CUPC. Serverhealth shows me "invalid credentials". When i take a look at the trace from CTIManager i get the following Errors:

CTI|Available Servers (2)|<CLID::StandAloneCluster>

CTI|authenticationLDAP::Authenticate():exit AUTH_NOT_INITIALIZED|<CLID::StandAloneCluster>

We are using an Openldap for Directory Synch and Authentication. It worked until we upgraded from 6.1.2 to 6.1.4. Any Idea how to troubleshoot?

The LDAP Synchronization works fine with SSL. My OpenLDAP Administrator told me that there is an corrupt SSL-Handshake in his Log at the Timestamp the CTIManager asks for Authentication.

Kind regards,

Go to CUCM > System > LDAP > LDAP Authentication. Change the port from 389 to 3268. Restart CTIManager on all nodes.

Re: CUPS 6.0.6 and CUPC 7.0.x DeskPhone Mode not working

Hi Michael,

thanks for your reply. I saw that you recommended the same solution in conjunction with LDAP Active Directory. Will this solution also work on OpenLDAP?

Actually we are not using the default (unencrypted) TCP-Port 389. Instead we're using the TCP-Port 8635 with SSL-Encryption for both Directory Synchronization and Enduser Authentication.

Is there a known Bug-ID?

Kind regards,
