No. JCIFS is a file service client. Even though in the past the code
has been hacked to provide a make-shift authentication service, that
functionality has been removed.

Note that JCIFS does include code to act as an *initiator* of NTLM
authentication (a client). But it cannot be used to act as an
*acceptor* of NTLM authentication (a server).
