This command returns the number of occurrences of username in the
NIS group database.
If you are using NIS+ to manage your group database, issue the
following command for each user in your domain:
niscat -M group.org_dir | /usr/bin/grep -c username
2. If any user is a member of more than 16 groups, remove the user
from some of the groups. See “To Modify an NIS Map” on page 164 for
instructions on modifying an NIS map. See “To Modify an Entry in
an NIS+ Table” on page 243 for instructions on modifying an NIS+
table.
If you are running a version of HP-UX older than release 9.0, a user
can be a member of only 8 groups, rather than 16.
If a user is a member of too many groups, NFS returns an RPC
authentication error when the user attempts access to files or directories
using NFS.
