BUG DESCRIPTION Unfortunately, it is currently not possible to set this kind of `force' flag with `password-store' as auth-source backend, as implemented in lisp/auth-source-pass.el. WORKAROUND As a workaround, users can just set `nntp-authinfo-force' to non-nil. But this will then of course affect all nntp servers, not just a specific one. BUG EXPLANATION The bug emerges as follows: - `nntp-send-authinfo' (lisp/gnus/nntp.el) calls `auth-source-search' and accesses the `:force' property of its car. - `auth-source-pass--build-result' (lisp/auth-source-pass.el) handles "host", "port", "user", and "secret" line-labels in password-store entries explicitly but no "force". POSSIBLE FIX One approach to fix this bug would be to teach `auth-source-pass--build-result' about `force':
