This section describes some situations that may result in error messages after enabling RADIUS to authenticate user login credentials. When the server and network engines NAEs NIEx9s are not configured for RADIUS authentication, the standard Metasys login error messages appear. When the server and network engines NAEs NIEx9s are configured for RADIUS authentication, RADIUS errors are intentionally obscured to hinder possible intrusion from unauthorized users. If you encounter these errors and cannot resolve them, contact your local network administrator. The two figures in this section are examples of the general RADIUS error messages.
The RADIUS error message Metasys User Interface Diagnostics: Fail appears in any of the following scenarios:
- The RADIUS server is not online or available when the non-local (RADIUS) user tries to log in to the Metasys system.
- The server or network engine is configured to communicate with a RADIUS server, but the RADIUS server is unavailable and therefore does not respond to a login request from the non-local user.
- The non-local user's account is disabled, either in the Metasys system or in the RADIUS server.
- The non-local user's account password has expired.
- The non-local user's account password does not meet the Metasys system password complexity requirements.
- The RADIUS server is enabled, but the Metasys local user account the operator is using is disabled, locked out, or cannot log in because the user's timesheet does not permit login at this time.
- The RADIUS server is enabled, but the Metasys local user account the operator is using is entered incorrectly.
The RADIUS error message Metasys User Interface Diagnostics: Invalid Credential appears if you try to log in to a server or network engine an NAE an NIEx9 with a non-complex password and RADIUS is not enabled.
