When configuring End Users to be App Administrators and CUCM is configured to synch with an Active Directory,the app admin account got deleted and app admin access is be lost. If this were the case, what would be the work around to getting back into App Admin if the AD connection is broken (besides waiting for the connection to be restored.)
You can run the initial setup wizard to choose new administrator users. Unfortunately, integrating with AD has it's pro's and con's....this is a con.
To get to the initial setup follow these instructions:
On the server:
Go to Start > Run, type CET then click OK
In the left hand window pane, click the AppAdminConfig
In the right hand window pane, double click the record that appears
In the pop up window, select the second tab
In the bottom drop down list, select "FRESH_INSTALL" then click OK
Exit out of CET
Launch AppAdmin and Login with Administrator/ciscocisco
Click next through all of the settings, including the license page
Get yourself to the end where you choose administrators, and pick a new one
No, you simply click next through the whole thing. It doesn't even disrupt call processing.
Also, one other con with AD integrations.
CUCM can have multiple AD servers listed for Authentication redundancy. CUCM will try a connection to a server up to 3 times before moving to the next server. This takes a little over 10 seconds per server.
CAD has a login timeout, which set to 10 seconds. So while the CUCM is busily trying to find an AD server to service the auth request, CAD has already timed out not allowing the login to happen.

The problem here is with the UCCX agents, because when you sync the CUCM with the AD and the user ID of the agents in the AD are different from the one that you use before in the CUCM, this will delete the agents, so you will going to do the whole thing again (add the agents to CSQ, etc), and as Anthony told before the CET tip doesn't affect any configuration, after that you can give an AD account the permission of being App Administrator.
