[Samba] write list parameter in 2.2.5?

[Eddie Lania]

Hello list.

I would like to administrate the [users] share.
But I am stuck with an access problem.
Please observe the following to see what I have done:

-----
[netlogon]
        comment = Network Logon Service
        path = /home/netlogon
        locking = No
        read only = Yes
        guest ok = Yes
        write list = joepie, @Administrators
        create mask = 0644
        directory mask = 0755

[homes]
        path = /home/users/%U
        read only = No
        browseable = No
        create mask = 0600
        directory mask = 0700

[users]
        comment = Users directories
        path = /home/users
        read only = No
        create mask = 0600
        write list = joepie, @Administrators
        directory mask = 0700
-----

When I log in as "joepie" on a client machine, I am able to open the [users]
share but I am not able to read/write to this share.
Any user directory on this share is not accessable, accept my own ofcourse.

I am using Samba 2.2.5 --with-ldapsam on RH 7.0 with openldap.
Everything else works OK.
In fact, the combination ldap and samba works great here.
I have no errors in debug. messages or samba logs.
And running /usr/local/samba/bin/testparm gives no errors too.

what am I doing wrong here?
Is this a bug, or is it my own mistake?
Am I correct in assuming that the "write list =" parameter should overrule
the default directory permissions?

I hope that anyone can help me.

Eddie.
