Manage Locks for Restricting Configuration Changes
You can use configuration locks to prevent other administrators from changing the candidate configuration or from committing configuration changes until you manually remove the lock or the firewall automatically removes it (after a commit). Locks ensure that administrators don’t make conflicting changes to the same settings or interdependent settings during concurrent login sessions.
The firewall queues commit requests and performs them in the order that administrators initiate the commits. For details, see Commit, Validate, and Preview Firewall Configuration Changes. To view the status of queued commits, see Manage and Monitor Administrative Tasks.

Unlock a configuration. Only a superuser or the administrator who locked the configuration can manually unlock it. However, the firewall automatically removes a lock after completing the commit operation. Click the lock at the top of the web interface. Select the lock entry in the list. Click Remove Lock, OK, and Close.
Configure the firewall to automatically apply a commit lock when you change the candidate configuration. This setting applies to all administrators. Select Device > Setup > Management and edit the General Settings. Select Automatically Acquire Commit Lock and then click OK and Commit.
