Easily create customized, multi-directional login forms. Control your users from a single login form that not only determines what group each user is assigned to, but automatically redirects each user to the appropriate folder and page.

Manages Unlimited Groups

Your Members belong to Groups and your Groups belong to Protected Folders. You determine which Protected Folder(s) each Group may access.

Manages Unlimited Users

A large database of users is only as good as the system that manages it. Use OSS to manage unlimited users with solid controls that allow you to view, edit, lock and delete accounts individually or by group

and much more.
