samba - Aug 2002 - Multiple domain question

Dear Samba org,

I'm a newbie to Samba but was able to get a basic set up running to allow
domain users to access unix files with:

[global]
        workgroup = COS_CM
        netbios name = MARYLAND
        security = SERVER
        password server = COSCC
        username map = /usr/local/samba/lib/users.map
        log level = 3
        log file = /usr/local/samba/var/log.%m
        wins server = 166.37.16.87
        valid users = @avs

[mdvobs]
        comment = VOB Storage area
        path = /space/mdvobs
        read only = No
        create mask = 0775
        directory mask = 0775

My question is how do I allow users from a second domain access to the same
"mdvobs" share?  Would the "[global]" section all be
duplicated?  Or - can
you add the name of the new workgroup/password server on the end of those 2
lines?  Or ??

thank you for your help.

Mark Jaskilka.
