RHBA-2012:0379 - Bug Fix Advisory

Topic

An updated ypserv package that fixes one bug is now available for Red Hat
Enterprise Linux 5.

Description

The ypserv package contains the Network Information Service (NIS) server, which
provides network information (login names, passwords, home directories, group
information) to all of the machines on a network. It can enable users to log in
on any machine on the network as long as the machine has the Network Information
Service (NIS) client programs running and the user's password is recorded in the
NIS passwd database. NIS was formerly known as Sun Yellow Pages (YP).

This update fixes the following bug:

• When requesting entries from a non-existing NIS map, the ypserv daemon

incorrectly returned 0 (YP_FALSE) instead of -1 (YP_NOMAP). This caused the
autofs utility to fail, and thus prevented file systems from being mounted
automatically. With this update, ypserv returns the correct return code and
autofs works as expected in this scenario. (BZ#788445)

All users of ypserv are advised to upgrade to this updated package, which fixes
this bug.
