authenticating directory server
In pass-through authentication (PTA), the authenticating Directory Server is the Directory Server
that contains the authentication credentials of the requesting client. The PTA-enabled host sends
PTA requests it receives from clients to the host.
authentication
(1) Process of proving the identity of the client user to the Directory Server. Users must provide
a bind DN and either the corresponding password or certificate in order to be granted access to
the directory. Directory Server allows the user to perform functions or access files and directories
based on the permissions granted to that user by the directory administrator.
(2) Allows a
client to make sure they are connected to a secure server, preventing another com-
puter from impersonating the server or attempting to appear secure when it is not.
authentication certificate
Digital file that is not transferable, cannot be forged, and is issued by a third party. Authentication
certificates are sent from server to client or client to server in order to verify and authenticate the
other party.
B
base DN
Base distinguished name. A search operation is performed on the base DN, the DN of the entry
and all entries below it in the directory tree.
