Subject: 25.3; authinfo password backslash problem
Date: Wed, 16 May 2018 17:56:01 +0100

Assumption: 
  User's IMAP password has a backslash character ('\') in it.

Steps:
  1. Setup gnus so it connects to an imap backend
  2. Start gnus
  3. Enter the username and password of the IMAP account
  4. Say yes to saving the credentials in .authinfo
  5. Quit emacs
  6. Restart emacs
  7. M-x gnus
  8. Authentication fails

The password saved in the .authinfo file has its backlash escaped
('\\').  If the file is edited directly and the extra backslash is removed,
authentication works again.

I cannot reproduce it here, using

In GNU Emacs 25.2.2 (x86_64-pc-linux-gnu, GTK+ Version 3.22.21)

The following is an extract of nnimap.el, which I have used for testing:

--8<---------------cut here---------------start------------->8---
(progn
  (require 'nnimap)
  (let ((credentials (nnimap-credentials "address" "imap" "user")))
    (funcall (nth 2 credentials))))
--8<---------------cut here---------------end--------------->8---

When I run this code snippet from a fresh Emacs started with "emacs -Q",
I am asked for

--8<---------------cut here---------------start------------->8---
IMAP password for user <at> address: 
--8<---------------cut here---------------end--------------->8---

I enter "test\user" (without the apostrophs). Then I'm asked

--8<---------------cut here---------------start------------->8---
Save auth info to file ~/.authinfo [y/n/Ne/?]
--8<---------------cut here---------------end--------------->8---

Now I type "y" (without the apostrophs), and see the result of the
evaluation in the minibuffer. And in ~/.authinfo, there is a new line

--8<---------------cut here---------------start------------->8---
machine address login user port imap password test\user
--8<---------------cut here---------------end--------------->8---

Looks like expected. Could you pls run the same scenario on your
machine? Maybe there's a difference because you use macOS, and I use GNU
Linux.

Best regards, Michael.

No reply, so I'm closing this bug.

Best regards, Michael.
