RHBA-2015:1312 - Bug Fix Advisory

Topic

Updated nfs-utils-lib packages that fix one bug are now available for Red Hat
Enterprise Linux 6.

Description

The nfs-utils-lib packages contain support libraries required by the programs in
the nfs-utils packages.

This update fixes the following bug:

• Prior to this update, the libnfsidmap library used "nobody@DEFAULTDOMAIN" when

performing name lookup, but this did not match the behavior of the rpc.idmapd
daemon. As a consequence, the nfsidmap utility did not properly handle
situations when "nobody@DEFAULTDOMAIN" did not directly map to any user or group
on the system. With this update, libnfsidmap uses the "Nobody-User" and
"Nobody-Group" values in the /etc/idmapd.conf file when the default "nobody"
user and group are set, and the described problem no longer occurs. (BZ#1129792)

• The nss_getpwnam() function previously failed to find the intended password

entry when the DNS domain name contained both upper-case and lower-case
characters. This update ensures that character case is ignored when comparing
domain names, and nss_getpwnam() is able to retrieve passwords as expected.
(BZ#1223465)

Users of nfs-utils-lib are advised to upgrade to these updated packages, which
fix this bug.

Solution

Before applying this update, make sure all previously released errata relevant
