[Samba] WinNT4 and Win2000 different behaviour authenticating to printer shares ?

[Mike List]

I have set-up a Samba server (FreeBSD 4.5 release and Samba 2.2.2) which is
used in our Office as a PDF-converter. The Server gets the file as a
Postscript file using a Samba Printer share and then sends it back to the user by
e-mail.

This all works excellent using Win2000 on the clients. The user prints to
the share PDF using a Postscript driver, the print job gets sent and a few
seconds later the PDF file arrives in the user's inbox.

Due to other software incompatibilities we are forced to use WinNT4.0SP6 on
some of our clients. If I do the same from those stations,  I can print to
the share, the file gets converted to a PDF but then is sent back to the user
"nobody". It seems like WinNT does authenticate differently to the printer
share than Win2000. %u gives me the user when printing to the share using
Win2000, but %u connecting with WinNT4.0 gives my the user "nobody" ( I tried with
different users and even different Service packs).

Can somebody give me a hint why this is happening and how I could get the
username when printing from the NT4.0 clients ?

Thank you for any help!

Mike
