Yes, and no.

There are various ways to have one password for all systems.  On Microsoft
Windows there is a security DLL and registry key that you can enhance with
your own routine.  This can relay the password information to your LINUX
system, so you can set it.

This seems to require that the modified dll be present on any Microsoft
Windows machine that you log in on.

An example with source is supplied with the Windows NT resource Kit CD-ROMs,
and may be available for download somewhere on the Microsoft site.

Not being experienced in that part of LINUX/UNIX, I am not aware of how
exactly PAM works, but it seems that it could be used to have your LINUX
system use the NT system to validate your signon.  If your smb.conf is also
set up with passthrough authentication, then all is well.
