We are running CUCM 7.1.3 and CUPS 7.0.8. Everything seems to be running fine. However, whenever we need to add a new user to Presence, we encounter a login problem. All existing users can login normally, but new users get a login failure. I have verified the password by logging into CCMUser successfully with the new username and password. I have them configured on the CUPS server, in the correct node with all the correct profiles. The CUPC Problem report just repeats the "Wrong username/password" error. I also looked at the Sync Agent logs when I changed the password and I see the username and other information being passed to the CUP Server, although the password was encrypted in the log, obviously. I have restarted the Cisco Tomcat Service and the Sync Agent Service with no luck.
The last time this happened, we renamed the account of someone who had left for the new user and this worked. When it happened before that, Cisco TAC said it was a bug in 7.0.6 and we need to upgrade to 7.0.8, which we did. The upgrade seems to have fixed it at the time, but now we are seeing the same thing.
