<p class="MsoNormal"><span style="color:#404040">LDAP authentication is used by Tomcat and isn’t just restricted to the Publisher server - Subscriber nodes handle this as well. DirSync is specific to synchronization of LDAP attributes and only runs on the Pub,
so synchronization would definitely be affected if the Publisher is offline. I suggest to check out the Tomcat Security logs off CUCM for more info on user authentication against LDAP and your source of failure.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#404040"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#404040">So to answer your question, LDAP authentication should still work when the Publisher is offline.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#404040"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#404040">For the UCCX agent concern, authentication of agents occur over AXL to CUCM, so if the AXL server is the Publisher, and that’s offline or experiencing issue w/ Tomcat during an authentication attempt by the UCCX
agent, then I would imagine seeing a failure. AXL and Tomcat Security logs off the UCM side should shed some light on that problem<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#404040"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#404040">As for SSO, I checked w/ my teammate and, in his experience, SSO can be handled by Subscriber nodes assuming the metadata was imported to those servers - authentication occurs against the IdP and not CUCM so
this seems logical to me as well.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#404040"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#404040">Hope this helps.<o:p></o:p></span></p>

<p class="MsoNormal">This has been our experience as well. Glad you started this thread. It's seems like a huge single point of failure to me for such an integral part of the process. I suspect hunt group login would also be affected. <br>

<p class="MsoNormal">Just trying to get some conformation, When LDAP Synchronization and authentication is enabled this is performed by the DirSync process that only runs on the CUCM Publisher. So If we lose the CUCM Publisher for whatever reason it would seem
that the Authentication also fails due to the single point of failure of DirSync. Should LDAP authentication still work if the CUCM Publisher is still down.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">So for LDAP users this would stop them signing in to Jabber clients and UCCX agents who are ldap’ed synced logging into the finesse webpages. Does anyone know is SSO is resilient on the CUCM publisher or would SSO still work in a Publisher
outage. <o:p></o:p></p>
