1. A 401 from ANY login step is reported as wrong password. auth-store.ts:61 classifies any error whose message merely contains the substring 401 as invalid_credentials, and it is fed by a catch-all around the entire login sequence. Reproduced with admin@sandbox.vnc.de, a Stalwart administrative principal with no mailbox: POST /api/auth/session returns 200 (the password IS correct), then the JMAP session fetch returns 401 and the UI claims the password is wrong. Verified directly: bernd.rodler gets 200 with a mail capability, admin gets 401. Cost several minutes re-typing a password that was never wrong. An admin-only principal, a disabled mailbox and a revoked mail permission are all indistinguishable from a typo. 2. Page reload signs you out unless stay-signed-in is ticked, which also silently prevents plugin activation and therefore looks like a plugin bug. SESSION_SECRET is intact, so not a key rotation. Neither blocks P1; both deliberately not chased during the spike. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Filed during the S/MIME spike, 2026-08-04. Neither blocks P1.
1. A 401 from any login step is reported as "wrong password"
stores/auth-store.ts:61
{ key: 'invalid_credentials', matches: ['Invalid username or password', '401', 'Unauthorized'] },
classifyLoginError is fed by a catch-all wrapped around the entire login
sequence (auth-store.ts:767), so any error whose message merely contains
401 becomes "Invalid username or password" — including a 401 raised well
after the credential check already succeeded.
Reproduced: admin@sandbox.vnc.de is a Stalwart administrative principal
with no mailbox. POST /api/auth/session returns 200 {"ok":true} — the
password is genuinely correct — but the follow-up JMAP session fetch returns
401 Unauthorized ("You have to authenticate first."), and the UI reports a
wrong password. Verified side by side against GET /.well-known/jmap with
Basic auth:
| Account | Result |
|---|---|
bernd.rodler@sandbox.vnc.de |
200 · 1 account · mail capability present |
admin@sandbox.vnc.de |
401 Unauthorized |
Cost observed: several minutes lost re-typing a password that was never wrong.
Impact: an admin-only principal, a disabled mailbox, and a revoked mail permission are all indistinguishable from a typo. Users retry credentials indefinitely and support chases the wrong cause.
Fix direction: distinguish a 401 from the credential check from a 401 raised
by a later step, and give the latter its own message (e.g. "This account has no
mailbox"). Matching on the bare substring 401 anywhere in an error message is
too broad regardless — it will also catch a 401 from an unrelated downstream
call, and any error text that happens to contain those digits.
2. Page reload signs you out unless "stay signed in" is ticked
Reloading localhost:3100 without rememberMe produces "Ihre Sitzung ist
abgelaufen". During the spike this also silently prevented plugin activation
(the sandbox loader only runs after a successful boot), which presented as a
plugin fault rather than a session fault — it cost two debugging cycles before
the real cause was clear.
.env.local SESSION_SECRET is intact, so this is not a signing-key rotation.
This may be the same complaint raised earlier about sessions expiring too
quickly — if so, the 6-hour jmap_stalwart_ctx maxAge added in
lib/stalwart/auth-context.ts did not address the real cause.
Unknown size until diagnosed. Deliberately not chased during the spike.
