OIDCRemoteUserClaim multiple values

[ftaddia]

Good morning,
I was wondering how to specify multiple values ​​in the OIDCRemoteUserClaim field.

In my case, I have two possible claims to authenticate the user:

1. eduPersonNickname
2. email

So if it finds eduPersonNickname first, it uses that; otherwise, it uses email. Is this possible?

Thanks

[zandbelt]

that should be possible by using mod_headers creatively and pull values from environment variables conditionally

Could you give me an example?
Is it possible to use some query params in the redirectUri?
