nss_ldap bug fix update

An updated nss_ldap package that fixes a bug is now available.

The nss_ldap package contains the nss_ldap and pam_ldap modules. The
nss_ldap module allows applications to use a directory server as a primary
source for information about users and groups.

By default, the nss_ldap module keeps connections to a server open between
uses. In order to avoid problems that would occur if two client processes
attempted to issue queries over the same connection to a server, the module
installs a fork handler to allow it to close the client-side of any open
connection for a newly-created child process. This method frequently
caused a SIGPIPE signal to be received by the child process, which in many
cases, caused the child process to exit.

This issue may have caused commands, such as "su" to fail, broken pipe
errors, cron jobs not running, scripts not running as expected, and remote
session hangs.

Users of nss_ldap are advised to upgrade to this updated package, which
resolves this issue.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
