Ticket 1566 on HSM, non-CA subystem installations failing while trying to join security domain Investigation shows that this issue occurs when the non-CA subsystem's SSL server and client keys are also on the HSM. While browsers (on soft token) have no issue connecting to any of the subsystems on HSM, subsystem to subsystem communication has issues when the TLS_ECDHE_RSA_* ciphers are turned on. We have decided to turn off the TLS_ECDHE_RSA_* ciphers by default (can be manually turned on if desired) based on the fact that: 1. The tested HSM seems to have issue with them (will still continue to investigate) 2. While the Perfect Forward Secrecy provides added security by the TLS_ECDHE_RSA_* ciphers, each SSL session takes 3 times longer to estabish. 3. The TLS_RSA_* ciphers are adequate at this time for the CS system operations
