• The Plugin will look for a CO Group with an identifier of Group Name Type with a value equal to the Username Type and, if found, assign that as the default group. For example, for the user jsmith the Plugin will attempt to find a group with Group Name Type identifier of jsmith. Note this is an Identifier attached to the CO Group, and not the name of the CO Group.
• If no such CO Group is found, a new CO Group will be created as follows:
  • The CO Group name will be constructed using the language key pl.unixcluster.fd.co_group_id.new.name
  • An Identifier of Group Name Type will be created, with the same value as the CO Person's Username Type
  • An Identifier of GID Type will be created, with the same value as the CO Person's UID Type
    • In order to ensure GIDs can be successfully assigned to matching UIDs, GIDs for other groups should be assigned in a different numeric space. As an example, if a CO Person has a UID of 1001, and a GID for the "Users" CO Group was also assigned 1001, then automatic GID assignment for the CO Person will fail, since the GID 1001 is not available.
      
  • The CO Person will be added as both Member and Owner of the new CO Group
  • The CO Group will be added as a Unix Cluster Group (see below)

Usernames and UIDs must be unique within a Unix Cluster.

Although not required, it is recommended that Usernames and UIDs be consistent across Unix Clusters to simplify management. (An exception might be for managing legacy clusters.) Keep in mind that Identifiers must be unique within a CO (within all CO People or CO Groups as appropriate). In order for (eg) two Unix Cluster Groups in different Unix Clusters to use the same GID Number (with different names), each Unix Cluster must have a different GID Type.

When a Unix Cluster Account is created automatically, subsequent management of these identifiers depends on the Unix Cluster's Sync Mode. More specifically, when an Account is automatically created it is given the Sync Mode setting of the Cluster, and so the individual Account's Sync Mode setting governs subsequent behavior. Changing the Cluster's setting will not affect the settings of existing Accounts.
