Need UID-TRANSLATION to connect to a Windows system

Cor Mom — Mon, 28 Jun 2010 19:17:15 GMT

Hi,

I have been asked to change an NFS mapping from OpenVMS to Unix into an NFS mapping from OpenVMS to Windows using Multinet. The existing mapping runs for many years now. What I need to know is how to define the uid-translation, because Windows does not use UID/GID.

Example op uid-translation to Unix:

ADD UID-TRANSLATION USER 318 21

Example op uid-translation to Windows:

ADD UID-TRANSLATION USER ? ?

The Windows support department gave me two names in stead of numbers and these will not be accepted bij Multinet.

In the Multinet documentation I found a statement that for Windows systems (PC-NFSD) also the Unix style UID/GID should be used, but how?

Please advise me what to do on either OpenVMS or Windows side to get the uid-translation work.

Thanks in advance.

I know nothing, but I believe that NFS
expects to use UNIX-like UID values, so an
NFS server on VMS needs to map UNIX-like UID
values to VMS users, and an NFS client on
Windows needs to map its own users to
UNIX-like UID values.

A while ago, I did a simple Google search for
keywords like, say:
windows 2008 nfs server
and:
windows 2008 nfs client
which lead to some interesting-looking
documents at microsoft.com, such as:

http://technet.microsoft.com/en-us/library/cc753302(WS.10).aspx

which suggests that there may be some kind of
ID mapping capability on (some kinds of)
Windows.

(Great user feedback on that one, too.)

You may know which version of anything your
"Windows" might be, so that might let you
guide your searches to something more
appropriate.

Hi,

Check the following link -
* MultiNet V5.1 Install & Admin Guide
http://www.process.com/tcpip/mndocs51/admin_guide/Ch28.htm
-> MultiNet NFS Client Use of User IDs
-> Grouping NFS Client Systems for UID/GID Mappings
-> Mapping Example

Hope this helps.

> I have been asked [...]

By the way, it's not entirely clear which of
your systems is an NFS server, and which is
an NFS client. I assumed that VMS was the
server, but the same basic argument would
hold in any direction. To the extent that
I'm making any sense at all, an NFS client
must present UNIX-like UID/GID values to an
NFS server, so it must have a mapping from
its local-user-ID to a UNIX-like UID/GID
pair. Similarly, an NFS server expects to
get UNIX-like UID/GID pairs from its clients,
so it must map those to its own local-user-ID
values.

Thus, any NFS action between VMS and Windows,
neither of which uses UNIX-like UID/GID
values naturally, would seem to demand a
user mapping scheme at each end, irregardful
of which is the client and which is the
server. (Which implies that you'll need to
find more than VMS or MultiNet documentation
to get this stuff to work.)

Hi,

Which MultiNet version is used?

MultiNet documents are available at following link:
http://www.process.com/tcpip/mndocs.html

Look at the relevant version's Installation & Administrator's guide to know about UID mapping.

Lets take a look from the Windows side.
You need a mechanism to make Windows know UNIX attributes.

Under W2k3 this is called SFU (services for UNIX) This is a Microsoft product and can be installed separately. See also:
http://technet.microsoft.com/en-us/library/bb463214.aspx

Under W2k8 this is called Identity management for UNIX and can be installed useing "add/remove programs, Windows components" See also:
http://technet.microsoft.com/en-us/library/cc737796(WS.10).aspx

Hope this helps
