Users in FlexiServer system can be assigned to different roles. Eg: Manager, Developer, Clerk, etc.
Each user's role property is set during user adding. It can modified later, but only by admin user.
Users added during initial step wizard are to "Unspecified" role, but can be modified afterwards. Total role list is shown in "Edit role list" on the main page of FlexiServer, which can be used to add or delete a role in the system.
Unspecified role is required by FlexiServer system and it is not allowed to be deleted.
