openldap security update

CentOS Errata and Security Advisory CESA-2012:1151

OpenLDAP is an open source suite of LDAP (Lightweight Directory Access
Protocol) applications and development tools.

It was found that the OpenLDAP server daemon ignored olcTLSCipherSuite
settings. This resulted in the default cipher suite always being used,
which could lead to weaker than expected ciphers being accepted during
Transport Layer Security (TLS) negotiation with OpenLDAP clients.
(CVE-2012-2668)

This update also fixes the following bug:

• When the smbk5pwd overlay was enabled in an OpenLDAP server, and a user
  changed their password, the Microsoft NT LAN Manager (NTLM) and Microsoft
  LAN Manager (LM) hashes were not computed correctly. This led to the
  sambaLMPassword and sambaNTPassword attributes being updated with incorrect
  values, preventing the user logging in using a Windows-based client or a
  Samba client.

With this update, the smbk5pwd overlay is linked against OpenSSL. As such,
the NTLM and LM hashes are computed correctly, and password changes work as
expected when using smbk5pwd. (BZ#844428)

Users of OpenLDAP are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. After installing this
update, the OpenLDAP daemons will be restarted automatically.
