It should use the Open ID Connect standard and not be limited to specific vendors.

Great to see open id connect coming.

I have a question: Is it possible to configure LDAP as user back-end while using open id connect for authentication?
I ask because open id connect doesn't provide passwords. This is handy when using APIs or Git HTTP URLs for checkout.

For security consideration, users from different authentication sources are currently managed independently, as different authentication sources can not guarantee uniqueness of login name, and also some authentication source allows user to change their login name freely.

So for now, users authenticated via OpenID can not clone project via HTTP protocol, and they can not access OneDev api (not available yet)

In future versions, user authenticated this way may create personal access token to access resources.
