The creds utility displays user and group information for the currently logged-in user for the local Windows host. The value of the user's primary group is affected by the CLEARCASE_PRIMARY_GROUP environment variable. If this EV is set, creds displays its value, which is used only for ClearCase processing. If this EV is not set, creds displays the user's Windows primary group.
creds also displays the user's ClearCase privilege status:
You do not have to be in the ClearCase administrators group to use ClearCase. However, members of this group have more privileges to create and modify ClearCase objects. See the permissions reference page for more information.
By default, creds displays the credentials for the current user. Lookup is done on the local machine.
Some ClearCase operations cannot evaluate group membership information for more than 32 groups per user. If the user is a member of more than 32 groups, creds lists only the 32 groups used by all ClearCase operations.
