REMOTE LOGIN ARRANGEMENT FOR HETEROGENEOUS SYSTEMS USING CENTRALIZED AUTHENTICATION

Methods and systems for authenticating a remote user across heterogeneous authentication systems are disclosed. One method includes receiving domain user credentials at a first heterogeneous authentication system, and transmitting the domain user credentials from the first heterogeneous authentication system to an authentication interface associated with a second heterogeneous authentication system. The method also includes transmitting the domain user credentials from the second heterogeneous authentication system to a centralized authentication system, and receiving at the authentication interface a validation message from the centralized authentication system, thereby authenticating the user. The method further includes determining a local username at the authentication interface based on the domain user credentials. The method includes using the local username to authenticate the user within the first heterogeneous authentication system.
