Question
How to reset the password of an admin user of the eAPP Management System?

If you forget the password of the admin user of the eAPP Management System, you can reset the password to the initial value (eLTE@com123). You can only reset the password as user root. After password reset, the eAPP Management System forces the user to change the password upon the first login.

NOTE:
In the master/slave server scenario, the password of user admin can only be reset on the master server. After the password of user admin is reset, the master server data is automatically synchronized to the slave server. That is, the password of user admin of the slave server is automatically reset.

Answer
Log in to the server remotely as user ubp (default password: eLTE@com123) using PuTTY. For details, see How to Log In to the Server in SSH ModeHow to Log In to the Server in SSH Mode? in
