The niscat -ocommand can be used to list the object properties and membership of an NIS+ group.
To list the object properties of a group, you must have read access to the groups_dir directory in which the group is stored. Use niscat -o and the group's fully qualified name, which must include its groups_dir subdirectory:
niscat -o group-name.groups_dir.domain-name
rootmaster# niscat -o sales.groups_dir.doc.com. Object Name : sales Owner : rootmaster.doc.com. Group : sales.doc.com. Domain : groups_dir.doc.com. Access Rights : ----rmcdr---r--- Time to Live : 1:0:0 Object Type : GROUP Group Flags : Group Members : rootmaster.doc.com. topadmin.doc.com. @.admin.doc.com. *.sales.doc.com.
Several of the group's properties are inherited from the NIS_DEFAULTS environment variable, unless they were overridden when the group was created. The group flags field is currently unused. In the list of group members, the * symbol identifies member domains and the @ symbol identifies member groups.
