Samba 2.2.0-alpha2 could'nt resolve secondary groupmembers

[Werner Maes]

In my humble opinion,

Samba only considers "primary" groups and not the "secondary" ones.
These are my experiences with Samba 2.0.7.

Kind regards,

I have a strange problem with unix-groups, access-rights and
w2k-workstations.
When i create a directory with the user "x", group "y"
and try to access this directory with
user "z" and group "z" and the secondary group "y",
samba don't see that the user "z" is the same group as the user "x" and
says "access denied".

How can i solve this problem?
