•	Log Out - Select to have the new administrator preempt other sessions.

NOTE: Selecting Log Out disables Non-Config mode and prevents entering Non-Config mode manually.

•	Allow preemption by a lower priority administrator after inactivity of (minutes) - Enter the number of minutes of inactivity by the current administrator that will allow a lower-priority administrator to preempt.

•	Enable inter-administrator messaging - Select to allow administrators to send text messages through the management interface to other administrators logged into the appliance. The message will appear in the browser’s status bar.

Enable Administrator/User Lockout

You can configure the Dell SonicWALL security appliance to lockout an administrator or a user if the login credentials are incorrect.

CAUTION: If the administrator and a user are logging into the firewall using the same source IP address, the administrator is also locked out of the firewall. The lockout is based on the source IP address of the user or administrator.

1	In the Login Security section, select the Enable Administrator/User Lockout on login failure checkbox to prevent users from attempting to log into the Dell SonicWALL security appliance without proper authentication credentials.

2	Type the number of failed attempts before the user is locked out in the Failed login attempts per minute before lockout field.

3	Type the length of time that must elapse before the user attempts to log into the firewall again in the Lockout Period (minutes) field.

4	Click Accept.
