nss_ldap bug fix update

An updated nss_ldap package that fixes various bugs is now available.

The nss_ldap package contains the nss_ldap and pam_ldap modules. The
nss_ldap module is a plug-in which allows applications to retrieve
information about users and groups from a directory server. The pam_ldap
module allows PAM-aware applications to use a directory server to verify
user passwords.

This updated package adds the following enhancements:

* when a system used a directory server for naming information, and
"nss_initgroups_ignoreusers root" was configured in "/etc/ldap.conf",
dbus-daemon-1 would hang. Running the "service messagebus start" command
did not start the service, and it did not fail, which would stop the boot
process if it was not cancelled.

* in master and slave server environments, with systems that were
configured to use a read-only directory server, if user log in attempts
were denied because their passwords had expired, and users attempted to
immediately change their passwords, the replication server returned an LDAP
referral, instructing the pam_ldap module to resissue its request to a
different server; however, the pam_ldap module failed to do so. In these
situations, an error such as the following occurred:

LDAP password information update failed: Can't contact LDAP server
Insufficient 'write' privilege to the 'userPassword' attribute of entry
[entry]

In this updated package, password changes are allowed when binding against
a slave server, which resolves this issue.

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

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