How to give Jira non licensed users access to Confluence

[automaiton-simplified]

Hi, We have a support portal linked with Jira. What I want to do is that all our customers i.e. non licensed users should be able to access confluence pages without performing any login.

I have already read about the Atlassian product Crowd. But, we do not want to configure that.

The thing I would like to know is that if there is any way to give Jira non licensed users the access to the confluence. 

What process I would not like to go through is:

1. Using crowd
2. Replicating list of users from Jira to confluence.
3. Making pages public so anyone could see those pages without login.

How I want it to be done:

1. Customer(non licensed user) logs in to the customer portal using his credential.
2. Customer clicks on FAQ section we have added on support portal which is a space on Confluence. 
3. FAQ space is opened on confluence for that user to view.

If you want your customers to have access to Confluence pages, you MUST allow anonymous access in Confluence and also anonymous access in the space you want to use. There is no workaround without any more products.

If you want anything that uses the logged user from Jira, you need custom development. For example, with a Single Sign On solution.
