[Samba] Unix Group Question with repect to Samba

[Bartick, Brett]

I have a question with regards to using Unix groups with samba. This might
be easier to explain with an example.

Lets say I have two users

UserID: GID
UserA:Group1
UserB:Group2

etc.....

I now have an entry in /etc/group that looks like

groupdev::UserA, UserB

If I have a directory with group ownership set to "groupdev" and group mode
"rws"
UserA & UserB cannot create a file in the share on their Windows machine.
But if they connect to the Unix host, no problem.
Does Samba understand user lists for group permissioning?

Thanks,
