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 :
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)
After installing this update, the OpenLDAP daemons will be restarted automatically.

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)
After installing this update, the OpenLDAP daemons will be restarted
automatically."
