perfect timing!

then you will need to see the "password API needed"  thread at
http://samba.anu.edu.au/listproc/samba-technical and write your own
database that has a c-to-perl interface on it.

although exactly why you would want to do this instead of writing your own
database api in c i do not know.

anyway, the interface is all there: see passdb.c in the latest cvs

wrong.  the LM and NT hashes are clear-text equivalent hashes.  they are
non-reversable and you cannot decrypt them.

in what way do you wish to validate against the semi-public NT
workstations, and what kind of "central user database" is it?  if you
intend to post a technical reply, please copy the message to
