samba - Jul 2010 - samba group members

Hi everyone,

When i add someone to a group using

    smbldap-usermod -G +(groupname) (username)

it does not add the user to the group in the ldap backend:

    smbldap-groupshow (groupname) | grep memberUid

The new member is not there! I have to mannualy add it to the user to 
the groups again. This is the expected behavior or i'm missing something?
