NOTE: Back up the /etc/passwd file before modifying it.

Remove all users from the /etc/passwd file, except the superuser, users with

administrative privileges, and system entries required for the system to boot and

function properly. System entries have user IDs less than 100.

The changes made to the /etc/passwd file on an NIS slave server must be identical

to the changes made to the /etc/passwd file on an NIS client.

For more information, see passwd (4).

Modifying Slave Server group File

This section describes how to modify the /etc/group file in the NIS slave server.

Modifying the /etc/group file in the NIS slave server is optional. Modifying the NIS

slave server /etc/group file enables the host running the NIS slave server to use the

information in the NIS maps to validate group login information using the configured

NIS domain instead of the local group file. If you do not modify the local group file,

only users defined in the local /etc/group file can log into the host. The users defined

in the NIS maps are not recognized.

Following is a sample /etc/group file on an NIS slave server:

root::0:rootl,sam

other::1:

bin::2:

sys::3:

adm::4:

daemon::5:

mail::6:

lp::7:

where:

root

field is empty.

is the numerical group ID.

rootl,sam

is a comma-separated list of all users allowed in a group.
