Cannot connect to JIRA or Crowd Directory

[Adam Wilson]

Hello Everyone! I am getting the following error when trying to connect Bamboo (or any other Crowd supporting Atlassian product) to either our Crowd instance, OR the JIRA internal Crowd.

Failed to change the active user repository: com.atlassian.crowd.exception.OperationFailedException: javax.net.ssl.SSLException: java.lang.RuntimeException: Could not generate DH keypair

My configuration is as follows:

• Oracle JDK/JRE 1.7u40
• OpenSUSE 12.3 (with latest updates)
• All services run behind Squid in Reverse Proxy mode.
• HTTPS port on firewall points to the Squid HTTPS port 3129

The problem is that my Squid OpenSSL configuration for DHE used a 2048 DHParams file. I solved this by reducing the OpenSSL DHParams to 1024 bits.
