In Novell eDirectory before 9.0.3.1 the LDAP interface was not strictly enforcing cipher restrictions allowing weaker ciphers to be used during SSL BIND operations.

Weakness

A protocol or its implementation supports interaction between multiple actors and allows those actors to negotiate which algorithm should be used as a protection mechanism such as encryption or authentication, but it does not select the strongest algorithm that is available to both parties.
