Elements and ownership

Each element in a VOB is assigned an owner (recorded as a numerical-form user identifier) and a group (recorded as a numerical-form group identifier).

The owner can be any user known to the VOB server's operating system. The group must be one of the VOB's groups: either the VOB's primary group or one of its additional groups. You can determine the primary and additional groups by describing the VOB and looking at the VOB ownership and Additional groups sections. For example:

% cleartool describe vob:/tmp/testvob
versioned object base "/tmp/testvob"
  created 2012-12-04T10:08:53-05:00 by Demo Account (demo.user@testhost)
  protected by rolemap: "DefaultRolemap"
  effective access for user "demo": Full
  VOB family feature level: 8
  VOB storage host:pathname "testhost:/var/tmp/testvob.vbs"
  VOB storage global pathname "/var/tmp/testvob.vbs"
  database schema version: 80
  modification by remote privileged user: allowed
  atomic checkin: disabled
  srfm: disabled
  evil twin detection: disabled
  VOB ownership:
    owner your.nis.domain/demo
    group your.nis.domain/user
  Additional groups:
    group your.nis.domain/developers
    group your.nis.domain/admins
  minimum client feature level: 8
  ACLs feature level: 8
  Attributes:
    FeatureLevel = 8

Because a VOB is managed by a process using the identity of the VOB owner and all the VOB groups, a VOB is limited in the number of additional groups—the limits of 16 (Linux or the UNIX system) or 32 (Windows) groups apply to the additional groups list.
