Abstract
A private network includes a plurality of network security appliances participating in authenticating end users. Each network security appliance maintains a locally stored user list. A first network security appliance receives at least a portion of a non-local user list comprising second user identifier records for a second network security appliance of the plurality of network security appliances. The first network security appliance compares the local user list with the non-local user list received from the second network security appliance to identify one or more deviations. The first network security appliance merges the portion of the second user identifier records of the non-local user list corresponding with the one or more deviations with the first user identifier records of the local user list to generate an updated local user list. The first network security appliance authenticates a request to access the network using the updated local user list.
