samba - Dec 1998 - Changing file permissions from NT

We run a Network of Suns (running Samba) and PC-NT (version 4, sp3)
machines, at work, and find it very annoying to be unable to change the
file permissions of files from NT on the Suns. Is there any way to
change the permissions from NT file explorer or otherwise ?

    We have this problem too, and we sended this message to samba-bug:

Subject:     NT failing when giving permissions
   Date:      Wed, 02 Dec 1998 23:49:17 -0200
   From:     Carlos Henrique <chenriq@homeshopping.com.br>

<samba-bugs@samba.org.au>

        Hi,
          I readed these mails in samba-ntdom list and I had the same
problem, but with:
        - Sun OS 4.1.4
        - Samba 2 beta 2
        - Win NT Wkst 4SP3 in Portuguese
        - Windows message: 0xc0000005, Address 0x778833aa

        Is it a bug?
        Have you any solution?

        Thank you.

I too have asked about this and really there is nothing much that can be done 
simply - basicly Windows sees a DOS filesystem (as offered by Samba) and all 
that can be changed is the Write bits (via read-only flag) and execute bits to 
match system and hidden attributes.

There is a work around in using "magic files" which allow a user to
execute
command under unix - a bit risky and too general in my view.

Of course you can set what the permissions will be for all files &
directories
within a share will be and by and large that is adequate.

See samba archives - back to 10th Nov - especially excellent summary by Mac
