After you have created one or more zones and separated the users and groups to ignore from the users and groups that you think should be migrated to Active Directory, you must decide which groups apply to which zones. For example, if you have some groups with the same group profile and group membership in all zones, you would import those groups into the top-level parent zone so that they also exist, with the same definition, in all child zones. If a group is only applicable for computers in a child zone, you can import the group profiles directly into that zone. You can also override group profile attributes on specific computers, if needed.
After you have made these decisions, importing the groups is a simple process using either the Import from UNIX wizard or ADedit scripts with two important considerations:
- Group names must be unique in Active Directory. If you create a group with a common name, such as admins, you cannot create another group with the same name.
- Having the same UNIX group name on computers in different zones can create group collisions and inadvertent privilege escalation or file ownership conflicts.
To prevent group name collisions, Centrify recommends that you include the zone name in the Active Directory group name. You may also want to add a suffix that identifies the group as an UNIX security group. In most cases, you create the Active Directory group object for the UNIX group in the UNIX Groups organizational unit if you created the organizational unit structure described in Creating recommended organizational units.
You should import group profiles and create the corresponding Active Directory groups for those groups before you import users. If you import group profiles first, you can resolve secondary group membership for users immediately after you import user profiles.
