MQ Authenticate User Security Exit (MQAUSX) is a solution that allows a company to fully authenticate a user accessing an IBM MQ resource. It authenticates the user's UserID and Password (and possibly Domain Name) against the server's native OS system, LDAP server, Microsoft's Active Directory, Quest Authentication Services, Centrify's DirectControl, or an encrypted MQAUSX FBA file.

The security exit will operate with IBM MQ v7.1, v7.5, v8.0, v9.0, v9.1, v9.2, v9.3 and v9.4 in Windows, IBM i (OS/400), Unix and Linux environments. It works with Server Connection, Client Connection, Sender, Receiver, Server, Requester, Cluster-Sender and Cluster-Receiver channels of IBM MQ queue manager.
