Mixed environments in which dynamic views on Windows® access
VOBs on Linux® or
on the UNIX® system
require a special user account on Linux or UNIX system to which the user credentials
for the Rational® ClearCase® server
process can be mapped.
The Rational 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 Rational 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 Rational 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 Rational ClearCase server
process user is a member of a single group, the Rational ClearCase administrators
group, which has special Rational ClearCase privileges
but no special privileges in the operating system. Even though some Rational ClearCase server
processes run as root on Linux and on the UNIX system, the Rational 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 Rational 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 Rational 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 Rational ClearCase server
process user on Windows.
