Can't we just implement ncadg ? We could have a
ncadg_unix_sock or perhaps a ncadg_samba (that
would use the messaging code) . That would allow us to use
the current testsuites and allow gathering data using even
Windows or programs based on FreeDCE. Also, it would allow the use of
the current pidl-generated ejs wrappers.
