Could a CVE be assigned to this issue?

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.
