Hello,

I'm currently using Authentik on a little VPS for my non-profit. However, it uses close to 500MB of RAM to handle ~10 users which eats up precious RAM space.

The reason I use Authentik for now is that it supports SAML, which is required for Google Workspace SSO. However, Google should deploy OIDC soon, the rollout is delayed for now but I hope it won't be too long...

Therefore, I'd like to migrate to rauthy once Google rolls out OIDC SSO, however the email claim should be set to a Google Workspace address, which does not match the email used by my users on IDP. With Authentik I can create a custom mapping and map a user attribute to the email claim.

From what I read on rauthy doc here and my testing with local test, I don't think that using an email coming from a custom field is possible, but maybe I'm mistaken?
