RADIUS Authentication for JIRA , is it possible?

Question

We have a local installation of JIRA  7.10, and we make it available to both internal and Internet users. Most users are internal and have an AD account, but there are also external users that don't have an AD account, but we still want to give them access.

We have a  Cisco ACS that we use to manage external user access for other products. I was looking for a way to have JIRA use RADIUS for authentication, so we could use the existing ACS accounts, instead of having to also manage internal JIRA accounts. We also have a different 2-factor RADIUS solution that we use.  I could not find a way to set up RADIUS in JIRA  in the product or documentation.  Is there an easy way to set up JIRA to use RADIUS?

update 20190730- we are now using 7.13.5, but the question is the same.

Not sure how this Crowd/LDAP article relates to the original RADIUS question, but just want to point that to hook your Atlassian application (i.e. Jira) to LDAP you do not require Atlassian Crowd, you can do that directly from Jira.

I just found this page : https://confluence.atlassian.com/adminjiraserver0712/connecting-to-crowd-or-another-jira-application-for-user-management-959313435.html and in the bottom there are 2 links to LDAP connections, which in my case would be doing the trick, I hope. You can add this via Administration --> User Management --> User directories. No idea whether it's already solved and/or an active question, but it seems Atlassian is really pushing their Crowd solution (very expensive) as THE tool....
