NFS Services Administrator's Guide

Configuring and Administering NFS Services
Prerequisites
Chapter 244
• Each group has the same group ID on all systems where that group
exists.
• No two users on the network have the same user ID.
• No two groups on the network have the same group ID.
You can set user and group IDs in the following methods:
• Using the HP-UX System Files (/etc/passwd and /etc/group)
•Using NIS
•Using LDAP
Using the HP-UX
System Files
If you are using the HP-UX system files, add the users and groups to the
/etc/passwd and /etc/group files, respectively. Copy these files to all
the systems on the network.
For more information on the /etc/passwd and /etc/group files, see
passwd (4) and group (4).
Using NIS If you are using NIS, all systems on the network request user and group
information from the NIS maps on the NIS server. For more information
on configuring NIS, see NIS Administrator's Guide (5991-7656).
Using LDAP If you are using LDAP, all systems on the network request user and
group information from the LDAP directory server. For more information
on configuring LDAP, see the LDAP-UX Client Services B.04.00
Administrator’s Guide(J4269-90064).
Verifying Group Restrictions
HP-UX supports 20 group entries per user, but the maximum number of
group entries supported by RPC is 16. If a user is a member of more than
16 groups, NFS truncates the number of entries to 16 when the user
attempts access to files or directories. Use the groups command to find
the group membership of a user. For more information on groups, see
groups (1). To ensure that a user is not a member of more than 16 groups,
use the following procedures depending on the user and group
configuration method you use:
• Using the HP-UX System Files
•Using NIS
•Using LDAP
