I need to configure a Samba *member* server. I do not want Zentyal to be an additional domain controller, it needs to simply be a *member* of our existing AD. I have been able to configure the Users & Computers module with External Active Directory and I can see all the OUs/users/groups, etc. in AD, but now there is no way to configure the "File Sharing" module (the item just doesn't appear in the list). Any help?
