3rd Party XMPP Client Connection with CUCM IM & Presence

[upchaurasia]

Hi,

I am trying to connect my XMPP client application with CUCM IM & Presence using Smack library.

I am able to connect over TCP but over TLS getting folllowing error-

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I have downloaded "CUCM XMPP" certificate from   CUCM IM & Presence and imported into java key store.

Does CUCM IM & Presence supports TLS connectivity for 3rd party client.

Thanks & Regards,

Umesh

Depending on the particular client/library you are using, you may need to import one or both of the 'cup-xmpp' and 'cup-xmpp-ECDSA' certificates from the IM&P OS Admin/Security/Certificate Management page.  Testing with Java 11, IM&P seemed to negotiate and return the cup-xmpp-ECDSA certificate for validation (which tripped me up for a long while, as I'd only imported the cup-xmpp certificate...)

Thanks David. I will try after importing both certificates.

Currently I have imported only cup-xmpp.
