Testing for Membership in an NIS+ Group

To find out whether an NIS+ principal is a member of a particular NIS+ group you must have read access to the group object. Use the -t option:

nisgrpadm -t group-name members. . .

This example tests whether the NIS+ principal topadmin belongs to the admin.doc.com. group. It is entered from a client in the doc.com. domain.

client% nisgrpadm -t admin topadmin
topadmin.doc.com. is a member of group admin.doc.com.

This example tests whether the NIS+ principal jo, from the sales.doc.com. domain, belongs to the admin.sales.doc.com. group. It is entered from a client in the doc.com. domain.

client% nisgrpadm -t admin.sales.doc.com. jo.sales.doc.com. 
jo.sales.doc.com. is a member of group admin.sales.doc.com.
