4.1 Domain Configurations Compatible with ClearCase LT

ClearCase LT is compatible with a wide variety of domain configurations. The simplest configuration-a single domain that includes all users, groups, and computers-entails the least administrative overhead, but other common configurations work equally well:

• Master and multi-master Windows NT domain configurations in which user and group accounts are created in a master domain and host (computer) accounts are created in one or more resource domains that trust the master domain.

• Active Directory domains that are part of a single forest.

• Domain upgrade and domain migration environments that support a combination of Windows NT and Active Directory domains.

What ClearCase LT Requires from Any Domain

ClearCase LT imposes a few simple requirements on any domain environment in which it operates:

• All members of a ClearCase LT community (all users who access the same VOBs and views) must have domain accounts and have at least one group membership in common.

• All ClearCase LT hosts must be members of a domain. If the hosts are not members of the same domain in which the user and group accounts are created, they must be members of a domain that trusts that domain.

• Additional steps must be taken to enable users from multiple domains to access a common set of VOBs and views.

ClearCase LT on Nondomain Hosts

Windows computers that are not in a domain can be ClearCase LT hosts, though with severely limited functionality:

• They cannot be ClearCase LT servers.

• They cannot access VOBs and views hosted on a ClearCase LT server running Windows.

Nondomain systems can function as ClearCase LT clients in networks whose ClearCase LT server is on a UNIX computer.

Nondomain systems can also function as stand-alone systems on which all VOBs and views are used locally. This situation typically arises when you are evaluating ClearCase LT software. For more information, see Installation Guide for ClearCase LT.

Nondomain systems can also function as stand-alone systems that act as both a ClearCase LT server and client. This situation typically arises when you are evaluating ClearCase LT software.
