RHBA-2014:1426 - Bug Fix Advisory

Topic

Updated openldap packages that fix several bugs and add various enhancements are
now available for Red Hat Enterprise Linux 6.

Description

OpenLDAP is an open source suite of LDAP (Lightweight Directory Access Protocol)
applications and development tools. LDAP is a set of protocols for accessing
directory services (usually phone book style information, but other information
is possible) over the Internet, similar to the way DNS (Domain Name System)
information is propagated over the Internet. The openldap package contains
configuration files, libraries, and documentation for OpenLDAP.

The openldap packages have been upgraded to upstream version 2.4.39, which
provides a number of bug fixes and enhancements over the previous version.
Specifically, Memory-mapped database library (LMDB) support in OpenLDAP has been
enabled. (BZ#923680)

This update also fixes the following bug:

• Previously, OpenLDAP did not properly handle a number of simultaneous updates.

As a consequence, sending a number of parallel update requests to the server
could cause a deadlock. With this update, a superfluous locking mechanism
causing the deadlock has been removed, thus fixing the bug.

Users of openldap are advised to upgrade to these updated packages, which fix
these bugs and add these enhancements.

Solution

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

This update is available via the Red Hat Network. Details on how to
