Cannot associate User with a DN

[Rainee Ortiz]

In an effort to associate a user with a DN, I get the following message:

Update failed. One of the required fields on the page has the same value as an entry that already exists in the database. Please check the corresponding Find List page to verify your entry does not exist.

After a synchronization with LLDP, it works for a while but then we are back to the same problem.

Any help will be greatly appreciated.

What version CUCM? Are you doing the association from the end user page or the DN page? Are you sure there is not a duplicate user ID in either end users or application users?

The problem was resolved by restarting tomcat and DBSync service on the server.

Thank you for the update.

Just to be clear. User ID already exists in the system and you are just trying to associate a Phone to it? Or are you trying to add the User ID and then you get this error?

If you are getting this error while adding the User ID then most likely it already exists.

Could you please explain a more about it. Are you trying to add it from User Page or DN page ?

If the entry doesn't already exist, you may have a database replication issue. 

Launch RTMT and run a database status report and verify your database replication is good or not. 

2 = good.

Below is a link that discusses troubleshooting database replication issues.
