Subject: 28.1; Authentication in Gnus using password-store backend of
 auth-source
Date: Wed, 26 Oct 2022 21:30:57 +0200

Hi,

As it is written in subject I can't authenticate to my local dovecot 
server when I have enabled pass backend in auth-source. I don't have 
this problem if I use default ~/.authinfo file. If it's not exist it's 
generated by Emacs and contains line as follows:
machine localhost login bk <at> asterio.cloud password pass

My minimal ~/.emacs file
(setq auth-source-debug 'trivia)
(setq auth-sources '(password-store))

(setq gnus-select-method '(nnnil ""))
(setq gnus-secondary-select-methods
      '((nnimap "localhost"
		(nnimap-address "127.0.0.1")
		(nnimap-stream network)
		(nnimap-authenticator login)
		(nnimap-server-port 1143)
		(nnimap-user "bk <at> asterio.cloud"))))

According to documentation [1] I tried numerous of entries of my user 
password in pass:
pass ls
Password Store
├── 127.0.0.1
│   └── bk <at> asterio.cloud
├── bk <at> asterio.cloud <at> 127.0.0.1
├── bk <at> asterio.cloud <at> localhost
└── localhost
    └── bk <at> asterio.cloud

But none of this works and in *Messages* buffer I have always following 
logs:
auth-source-backend-parse: invalid backend spec: password-store
auth-source-search: found 1 backends matching (:max 1 :host ("localhost" 
"127.0.0.1") :port (1143 "imap" "143") :user "bk <at> asterio.cloud" :require 
(:user :secret) :create t)
auth-source-search: found 0 results (max 1) matching (:max 1 :host

auth-source-search: CREATED 0 results (max 1) matching (:max 1 :host

"bk <at> asterio.cloud" :require (:user :secret) :create t)
Opening nnimap server on localhost...failed:

I don't try this backend and library in other situations (e.g. TRAMP) so 
I am not sure it's more related to Gnus or Auth-source.
