Abstract

A method, non-transitory computer readable medium, and network traffic management apparatus that receives an authentication request from a user of a client computing device, the request comprising credentials for the user. A connection is established with a selected one of a plurality of active directory servers using a stored Internet Protocol (IP) address for the selected active directory server. At least a portion of a fully qualified domain name of the selected active directory server is received in response to an anonymous lightweight directory access protocol (LDAP) query sent to the selected active directory server using the established connection. The user of the client computing device is authenticated using the at least a portion of the fully qualified domain name and the credentials.

What is claimed is:
