This event is generated when the DSA fails to authenticate the
 originator of a Bind request.  The event returns the following
 information:

 -    The reason why authentication failed. This may be one
      of the following:

      -  Unknown User.
         The distinguished name supplied in the Bind request does not
         identify an entry within the directory.

      -  Incorrect Password.
         The password supplied in the Bind request does not match the
         password stored in the directory entry identified by the
         supplied distinguished name.

      -  Inaccessible Password.
         The DSA could not verify the supplied password because the
         DSA containing the directory entry is not accessible. This
         might be a temporary problem, for example, the connection to
         that DSA cannot be made, or it might be a more permanent
         problem, where the DSA holding the directory entry is not
         a trusted DSA.

      -  Password Verification Loop.
         When a DSA attempts to verify a password, it might need to
         communicate with another DSA to access the directory entry
         that contains the password. This communication might also
         require the specification of a password, which must be
         verified by the second DSA. It is therefore possible that
         two DSAs will find themselves in a situation where each is
         waiting for the other to verify a password. If this happens,
         one of the DSAs detects the problem, and the authentication
         fails.

 -    Information on the application or user that requested the
      operation. This comprises:

      - The application entity title of the DSA from which the Bind
        request was received.

      - The presentation address of the DSA from which the Bind
        request was received.

      - The distinguished name that was supplied in the Bind request,
        if any.

      - The directory protocol in use, that is DAP, DSP, DISP, or DOP.

 The DAP protocol is used by directory applications to bind to the DSA.
 The DSP protocol is used by other DSAs to chain requests to the DSA.
 The DOP protocol is used by other DSAs to manage shadowing agreements.
 The DISP protocol is used by other DSAs to replicate information to
 or from this DSA.
