A user region map is a file that maps registry regions to users or groups. You can create one of these files to limit VOB access to specific users or groups. User region maps are supported only by the Rational ClearCase remote client.
A region map controls the set of VOBs that a user can specify in load rules. Adding or changing a region map after load rules have been created can cause unspecified behavior if VOBs from which resources had previously been loaded do not have tags in the region to which a user is mapped.

The region map takes effect the next time a Rational ClearCase remote client user connects to the server host.
