"""
It was reported that OpenLDAP, when using the Mozilla NSS backend, would ignore any TLSCipherSuite configuration settings.  When the TLSCipherSuite setting is configured, OpenLDAP would use the default cipher suite, ignoring the setting.

While the default cipher suite contains some weak ciphers (e.g. MD5-based), it is still not easy to break the encryption to obtain sensitive information.  However, if an administrator wishes to enforce the use of stronger ciphers by overriding the defaults using TLSCipherSuite, they should be able to trust that, when the configuration items is in place, the stronger ciphers are used.  Due to this flaw, that is not the case.
