Each AccuRev user must have an AccuRev username (also called a “principal-name”). AccuRev maintains its own user registry, which is separate from the registry maintained by your machine’s operating system (or the network).
Optionally, you can create AccuRev user groups, and add users to the groups as “members”. Starting in Version 4.5, groups can be nested within one another; that is, a group can be a member of another group. AccuRev groups are independent of operating system groups.
Each AccuRev group has a user-defined name. Usernames and group names share a “namespace” in AccuRev. This means that a user and a group cannot have the same name.
