Go2Group is pleased to announce the release of Client Certificate Authentication 3.5.


This is a major release with 1 major bug fix update. The license calculation in Confluence was not working for Confluence previously. If you are unable to install the CAC license into Confluence, please upgrade to this version.

We have now included a Basic mode for configuring the CAC application in JIRA and Confluence.

The Basic mode allows administrators to convert the CN from ssl_client_s_dn into an Atlassian username by using a drop down select list. For example, C=US/O=U.S. Government/OU=DoD/OU=PKI/OU=ABC/CN=JOHN.RANDOM.DOE.9999999999 can be converted to:

  • john.doe
  • jdoe
  • johndoe
  • 9999999999
  • john.middle.doe

For the existing configuration screen that was introduced in version 3.0, it can be found in the Advance mode tab.

At the moment, version 3.1.x only supports JIRA, Confluence and Crowd. We're working hard to release a version of the solution that would work for the rest of the Atlassian applications.


Users can request for a download (along with the documentation) from our Service Desk at:

Upgrade Guide

In general, if you are coming from a previous version of the solution, users will have to revert the installation procedures to remove the current setup. After that:

JIRA, Confluence, Bitbucket Server


  1. Retrieve your .jar
  2. Head over to the application's UPM
  3. Upload the .jar
  4. Head over to the application's administration screen and look for CCA Authentication Configuration link
  1. Retrieve the binary from your Jira Issue
  2. Stop Crowd
  3. Replace the Crowd’s applicationContext-CrowdSecurity.xml with Go2Group’s supplied file. This file can be found at $CROWD_INSTALL/crowd-webapp/WEB-INF/classes (make sure that you save / backup a copy of the file in case you need revert / remove the CCA).
  4. Place the ccacwd-x.x.x.jar in $CROWD_INSTALL/crowd-webapp/WEB-INF/lib

Version Matrix

This page contains the version matrix for the Client Certificate Authenticator solution.

  • If the version is not on the list, it is not supported
  • Goldfinger Holdings assumes that the add-on works because the code compiles against x.y. If it does not work for any x.y.z, please raise a support ticket at our JIRA instance
  • Strikethroughs on the App version(s) means that we do not support that version anymore
