What is required to connect Trello to Jira Core (on premise -> moving to data centre).

[Sandra Wheeler]

Hi, I'm looking for clarification around the Using the Jira Power Up documentation, with regards to connections being made to an on-premise JIRA instance. The documentation states that 

However, please be aware that your Jira Server has to be accessible on the public internet and not be behind SSO.

I'm currently investigating the feasibility of having this functionality installed at my workplace, where we are using the on premise versions of both. The technical team have asked me what is meant by the above statement. We use Crowd at present for authentication into our JIRA and Confluence instances, and are looking to move to AD as part of an upgrade to the data centre versions. Is this what is meant by SSO? Doe it only mean that JIRA can't be behind a firewall? I've been looking for some technical documentation on this and haven't found anything beyond 'configure this and that and voila! it will work'. 

Thanks,

Sandra Wheeler.

Hi Sandra,

The documentation definitely could be a bit more clear. To speak for your specific situation, the powerup should work fine with your current (Crowd) and future (AD) configuration. I've personally used the Server plugin / Trello powerup on a Server instance that used ADFS for authentication and had an LDAP connection to AD on the backend.

Trello does need to be able to connect to Jira to complete the authentication and then create issues going forward. If your Jira server is addressable from the internet (you can log in to Jira from home without using a VPN as an example) then you should be set for that portion. I think the target of the "not behind SSO" wording is organizations that are using Google or Okta/CAS where Jira might not be able to verify credentials without user intervention. A User Directory configuration with AD definitely works fine, and Crowd should work fine.

Cheers,
Daniel
