Need a free option for Identity/Claims Management in ASP core

[weedkiller]

From today Identity Server is no longer free

I work for mom and pops stores who cant afford to be in this position. There was a huge commitment to using your framework and lot of work has gone in by @skoruba and others here.

So, for the health of the project we need to see an option to use a different backend other than Identity Server. I just hate that MS dropped the ball on something so important. This core component should have been a feature in the main framework.
