After updating Domino to 9.0.1 FP9 you cannot connect to Domino using SSLv3 despite not having DISABLE_SSLv3=1 set on the server
Due to a large number of customer requests IBM Domino development disabled SSLv3 by default in the Domino security stack from Domino 9.0.1 FP9.
This action was taken under SPR # DKENAKNSEG and will affect all connection types that utilise the native Domino security stack such as HTTPS and secure DIIOP
Diagnosing The Problem
Messages on the server console will indicate that a connection was rejected due to the use of SSLv3
Resolving The Problem
If your organisation requires Domino to support SSLv3 connections, you must enable the following parameter in your server's notes.ini file and restart your server to have the parameter take affect.
