To change an object's owner, use the following syntax:
nischown new-owner object
new-owner is the fully qualified user ID of the object's new owner.
object is the fully qualified name of the object.
Be sure to append the domain name to both the object name and new owner name.
The example below changes the owner of the hosts table in the doc.com. domain to the user named lincoln whose home domain is doc.com.:
client% nischown lincoln.doc.com. hosts.org_dir.doc.com.
