Problem Description
An error occurred when logging into the web page after the first CAS installation:
Process Analysis
I logged into the backend database to check all users and found only three(sysadmin, secauditor, secadmin); there was no "admin" user.
Because CAS was configured in the role-based access control mode during installation, logging in with the admin account failed, but logging in with other usernames and passwords was successful.

Solution
Use sysadmin, secadmin or secsuditor to login.
If the role-based access control mode is not required on site, the CAS will have to be reinstalled.
