Would it be possible to have this merged in the 5.8.x branch alongside main even though it's a new feature ? We're still using spring 5

Sorry, @1livv, that I missed your earlier comment about 5.8. Generally, our policy is to only backport bugs to 5.8.

In the meantime, I believe you have the option to override the provider setting in RelyingPartyRegistration. Have you already tried that as a workaround?

[1livv]

Thanks for the workaround @jzheaux that works ? Do I need to make my PR against main now ?

[jzheaux]

Yes, @1livv, it would be best to rebase on main.

[1livv]

@jzheaux rebased it

[jzheaux]

Thanks, @1liv! This is now merged into main.
