A user can be a member of one or more groups, one of which is distinguished
by Rational® ClearCase® as
the user’s primary group.
Rational ClearCase users
who access a common set of resources should have the same primary group membership
wherever possible. This group can be an existing one, or you can create one
for this purpose.
The definition of the primary group is controlled by the operating system
of the host on which a user authenticates:
- On Linux® and
on the UNIX® system,
the primary group is defined in the user’s entry in the NIS passwd database.
- On Windows®, the primary group is specified when the
user’s domain account is created. However, if the user is a member of multiple
groups, the primary group name is not always returned when an application
requests it. Any Rational ClearCase user
who is a member of multiple groups must set the user environment variable
CLEARCASE_PRIMARY_GROUP to the name of a group of which he is a member and
that has been designated the primary group for Rational ClearCase users
on Windows (see Setting the Rational ClearCase primary group).
Note: To avoid having VOBs created with an owning group that is privileged,
the primary group must not be one that is designated as privileged. For more
information, see
Privileged users and groups.
