Claim:
A method for providing security authentication of an intended user of a database, the method comprising: in response to a request from a user for access to a database of a server, concurrently requesting via an administrator of an operating system authentication both: from a directory access protocol database layer security plug-in of the server using input of a user identifier, a password and a code that identifies the security plug-in, through a directory access protocol application program interface; and from an operating system of the server through an operating system procedure call that does not require input through the directory access protocol application program interface of the user identifier, the password and the code that identifies the security plug-in; granting access to the user to the database based upon a first one of the security directory access protocol security plug-in and the operating system providing a positive response to the request authenticating the user, and withdrawing the request from the other of the directory access protocol security plug-in and the operating system; and if neither of the directory access protocol security plug-in and the operating system provide a positive response to the concurrent requests authenticating the identity of the user, denying entry to the database by the user and returning an error signal to the user.
