This tab is only visible if you are authorized to assign roles to users for the selected object.
Note
Be careful with assigning roles to users. As a rule of thumb, assign the minimum number of roles necessary at the highest level possible. This rule will make it easier to work out which permissions a user has for a project, folder, document or document revision.
To remove a user from a role, select the role concerned. Select in the pane "Users for <role name>" the user you want to remove and click the button .
This setting determines if changes made to the authorization of the project or folders also apply to its child objects.
By default this setting is on which means that you only have to assign Roles on the project level to assign them for all objects inside that project. Switching this setting off by unchecking the check box blocks all changes to the authorization made in containing objects.
For a more detailed explanation refer to the chapter Roles and Authorization in the ITP/MDK Repository Manual.
