4.202. ypserv

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

Bug Fix

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