  • Log in to Clish over Console connection works correctly (user is able to log in without any errors).

  • /var/log/messages files shows:

    sshd[PID]: Accepted password for admin from X.X.X.X port XXX ssh2

    clish[PID]: user logged from admin
    clish[PID]: User admin logged out due to an error from CLI shell
    sshd[PID]: Received disconnect from x.x.x.x: 11: Connection discarded by broker
    sshd[PID]: pam_unix(sshd:session): session closed for user admin
Cause

Due to some locking issue related to authenticating through RADIUS, the Clish shell remained locked, although the RADIUS session was closed and the Clish shell should have been released for use.
