Besides the content you require user management within the LMS?
OLAT lets you organize users in groups and different roles within. Wether it is a project or a learning group, it gives all participants a space to contact other group members via E-mail and the Chat, or to work together in a Forum and the use of a Folder or Calendar. Only a group owner has the right to manage these groups: he decides which tools can be used and add members, tutors or other owners of that group.
The learning groups especially, give you the chance to manage access to a course or only some of its elements. Through certain restrictions, only group members are able to access the content and only in that way it is defined by you and other course owners. For example, only allow students to read a Blog content but not create an entry of their own. This way you can manage access to all the course content in different settings.
