Credentials for the DevOps Code ClearCase server process user on Linux and the UNIX system

Mixed environments in which dynamic views on Windows® access VOBs on Linux or the UNIX system require a special user account on Linux or the UNIX system to which the user credentials for the DevOps Code ClearCase® server process can be mapped.

About this task

The DevOps Code ClearCase server process user account is a special Windows domain account (see Domain user and group accounts) under whose identity the albd_server runs on Windows computers. No server processes on Linux or the UNIX system run with the identity of this account. It is used only for credentials mapping when the DevOps Code ClearCase server process user requests access to a VOB or dynamic view on Linux or the UNIX system.

You can create a new account for this purpose or use an existing one. Either way, the following guidelines apply:
  • The account must be a member of each group that owns a VOB or dynamic view hosted on a computer running Linux or the UNIX system that will be accessed from Windows.
  • The account’s primary group must have the same name as the primary group designated for DevOps Code ClearCase users on Windows. (If it does not exist, you must create this group on the system running Linux or the UNIX system.)
    Note: On Windows computers, the DevOps Code ClearCase server process user is a member of a single group, the DevOps Code ClearCase administrators group, which has special DevOps Code ClearCase privileges but no special privileges in the operating system. Even though some DevOps Code ClearCase server processes run as root on Linux and on the UNIX system, the DevOps Code ClearCase server process user account should not be mapped to root. Privileged user status is not required for this account, and mapping it to root might create a security risk.
  • The account can have any name that is convenient, unless either of the following conditions are true:
    • Windows computers use an NFS client to access VOBs and views on Linux and the UNIX system; that NFS client does not allow you to map the DevOps Code ClearCase server process user account to a Linux or UNIX system-based account with a different name. (For more information, see NFS client products.)
    • VOB and view server hosts running Linux and the UNIX system run an SMB server to provide Windows computers with access to VOBs and views, and you do not want to map the DevOps Code ClearCase server process user account to an existing account on Linux or the UNIX system. (For more information, see SMB server products.)

    In either case, the account on Linux or the UNIX system must have the same user name as the DevOps Code ClearCase server process user on Windows.
