The Application user for GUI access say Administrator can be changed.
This id cannot be changed once set but the password can be changed from CLI. This is different from CUCM GUI access which can be an id like ‘ccmadmin’ or ‘ccmadministrator’ or could be anything. Most people normally set it to ‘Administrator’. This is the same ID which is used to get SSH access to CLI of CUCM. SSH to CUCM – the Administrator ID can not be changed once you have set it during Installation. In that case you can still login to CUCM GUI by adding another user from CUCM CLI. You will come across this situation where the customer forgot the CUCM GUI Admin username or password or both.
