> ZTN does not check for the user. It only checks issuer and audience. A ZTN token does not require authorization data, only enough to demonstrate it is from a trusted issuer. At least that is how I understood our original discussion. Right, that much I was following -- the piece I missed is why reusing the token layer implies a subject attribute is now required (or whether there's a protocol issue). That's all up to what the later authorization framework wants to see to evaluate the authorization of a request. Maybe it decides to allow read requests if and only if the first letter of the token is `B`! -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1584#issuecomment-1035145996 You are receiving this because you commented.
