I have already setup LDAP server where users will register through web and after manually I approve them and they can login on joomla website . Now I have 2 extra joomla websites and I need modify existing LDAP server so I can approve users for Example Joomla1 and Joomla3 website but to Joomla2 member can't login . I will attach picture so you can see current panel . When someone register I just click on name and click approve . So I think maybe create bellow name extra checkboxes and before I click approve I will choose to which website to give access to the member . And maybe change little bit design of the page so it's looks better .

The Operating system is Debian 6
Joomla 1.5 and 1.6 websites .
