Is it possible to add new roles to OpenKM users?
Yes, but remember that all users must have a UserRol. In OpenKM 3.0 user management is a administration option. There you can create roles ( first time creation is so simply as typewriting new role and assigning to a user). Older OpenKM version use properties files for these the example, if you want to two roles named AdvancedRol and DeveloperRol, using text-based user management you must put something like this: user1=UserRol,AdvancedRol user2=UserRol,DeveloperRol, AdvancedRol Note that all users have one defined UserRol and, optionally, others.
