SNMP walk initially shows a text value for "user name". When the user logs off the firewall SNMP walk now returns " No Such Instance currently exists at this OID". This is correct.

Zabbix initially displays the user name as text in a plain text widget, when the user logs off the firewall the plain text widget still displays the users name, it should be cleared since the item is now "not supported" rather than enabled.
