Opened: Jan 09, 2025 Severity: 4-Minor
If you try to establish a session on a system that exceeds the restconf-max-session-limit, the new session will be unsuccessful. Instead of the current generic error message "Authentication failed," a more precise message should be provided to explain that the authentication failed due to exceeding the restconf-max-session-limit, such as "You have exceeded the restconf-max-session-limit."
The error message does not provide precise details as to why the new session could not be established.
If restconf-max-session-limit, the limit on GUI sessions, is set, then the user will be able to establish a restconf-max-session-limit number of GUI sessions on a system. If the user then attempts to start more than the restconf-max-session-limit number of sessions on the system, they will get the error message: “Authentication failed.”
This is a cosmetic issue related to the contents of an error message. If the creation of a new GUI session fails and the error message “Authentication Failed” is present, then the user needs to check the value of restconf-max-session-limit and ensure that they have not started too many GUI sessions on the system.
