But *if* it takes a long time that indicates problems.  The Secrets API
backend in auth-source.el, for instance, is much slower than the netrc
backend.

Can you try Michael's patch and example I cited and see if it works for
you?  I think it's OK and if you are happy with it, should go into
Emacs.

I brought the discussion back under this thread because the other one's
subject ("auth-source-search: annoying messages") was not as
appropriate.  Sorry for the confusion this may cause.

Thanks
