@sscarduzio, you said in an email
you can configure the proxy to inject headers like “x-forwarded-user” and “x-forwarded-groups” so that ReadonlyREST can use that for authentication purposes.
What I thought you meant was that GRP would get populated with
x-forwarded-groups in the same way that USR does for
x-forwarded-user. But this seems not to be case. Indeed I can find no trace of
x-forwarded-groups in the code.
Where you referring to a possible future capability?
