The Roles page can be used to manage roles in UniTime. A role is a collections of permissions that are managed on the Permissions page. Unauthenticated users have Anonymous role, authenticated users with an appropriate record (with the matching external id) in the students table have Student role, instructors have Instructor role, and timetabling managers have one or more roles that are assigned to them on the Timetable Managers page. Authenticated users with no match against students, instructors, and timetabling managers have the No Role role.
A role has a reference and a name. It can be enabled or disabled. A disabled role cannot be assigned to any authenticated user.
Some roles can be assigned to instructors (and other department personell) using the Instructor Roles page. This allows schedule managers or event managers to dedicate some role to additional members of the department without cluttering the Timetable Managers page too much. For instance, certain departmental users may be allowed to approve / reject events that are requested in the event rooms of the department.
The reference of the roles Anonymous, No Role, Student, and Instructor role cannot be changed and these roles cannot be deleted. They can be disabled though. The anonymous role is useful when certain pages (e.g., Events page) are to be available to unauthenticated users. The no role role can be used when anyone at the university (who can be authenticated within UniTime, e.g., using LDAP authentication) can for instance request an event (e.g., Add Event page) see a timetable of a room (e.g., Room Timetable page).
The table can be ordered by any of the columns. To do so, click on the column header and select Sort by <column name> option.
