openldap bug fix and enhancement update

Updated openldap packages that fix several bugs and add an enhancement are
now available.

OpenLDAP is an open source suite of LDAP (Lightweight Directory Access
Protocol) applications and development tools. The openldap package contains
configuration files, libraries, and documentation for OpenLDAP.

These updated openldap packages provide fixes for the following bugs:

* the slapd server with the BDB backend no longer crashes when multiple
clients are modifying one attribute simultaneously.

* the slapd server with the BDB backend no longer leaks memory when adding
or modifying attributes.

* the entryUUID attribute is now correctly replicated to slave LDAP servers.

* the OpenLDAP client library now properly authenticates with an LDAP
server when chasing referrals using SASL authentication.

* the init script now reports a warning if the slapd daemon cannot read a
TLS certificate file.

In addition, these updated packages provide the following enhancement:
OpenLDAP client tools now allow their Bind timout to be configured, using
the '-o nettimeout=x' command line option, where 'x' is a number indicating
the timeout length in seconds.

Users are advised to upgrade to these updated openldap packages, which
resolve these issues and add this enhancement.

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