I do not want to use the mkpasswd because I have 500 user on the network
and only 6 - 10 will be using Cygwin.
I tried to put only on entry in the /etc/passwd and cygwin uses this
user name but I do not know if this is a bug or a feature.
I would of expected cygwin to send a authentication error ...???

Please do not commandeer an unrelated thread for a new topic.  Changing
the subject is not enough -- you have to post a new message altogether
if you want to break the thread.

I don't believe it's possible.  First off, entries in /etc/passwd
contain an SID that identifies the associated Windows user, so you'd
need to have one entry per Windows user anyway, or they will be
unrecognized by Cygwin.

You can have multiple entries in /etc/passwd with the same username, but
when Cygwin looks up a username, it stops at the first one, so anyone
trying to log in with that username will be treated as the first
matching user (and will need to enter the password for that user).

On the other hand, you can use the mkpasswd tool to manage your
/etc/passwd file instead of doing it by hand.
