system auth restart
The system auth restart command restarts the remote authentication subsystem and applies the currently configured remote authentication settings.
The remote authentication subsystem communicates with LDAP, OMS, RADIUS, or TACACS+ systems and must be restarted after any changes are made to how authentication is performed.
Restarting the remote authorization subsystem is transparent to any users logged into the system. In other words, they will not notice the change until they log out and log in again.
Use show auth settings to ensure all settings are correct before proceeding.
