Jean 2f9790feac auth: offload IDENTIFY + SASL PLAIN verify off the engine lock ... Both ran scram verify_plain (~1s PBKDF2 at 1.2M iters) inline under the engine lock, freezing the whole daemon per login. Add NetAction::DeferAuthenticate + AuthThen continuation + ctx.defer_authenticate, mirroring DeferPassword: the module/SASL path fetches the verifier cheaply and defers; the link layer runs verify_plain on spawn_blocking, then Engine::complete_authenticate finishes the login (IDENTIFY reuses the same ctx helpers, so its login/AJOIN/vhost/memo side-effects are unchanged). Tests resolve the defer inline (cfg(test)). The gRPC web-login path was already fixed; no login path stalls services now. (GHOST/DROP/CERT/GROUP still verify inline but are rare account ops, not logins.)		2026-07-16 19:04:18 +00:00
