I have issue with my TRAMP. I am using `exec-path-from-shell` package, I have properly configured in emacs environment variables:
```
#+begin_src emacs-lisp
(getenv "SSH_AUTH_SOCK")
#+end_src
#+RESULTS:
: /tmp/ssh-XXXXXXB00fvW/agent.12069
#+begin_src emacs-lisp
(getenv "SSH_AGENT_PID")
#+end_src
#+RESULTS:
: 12070
```
I run `M-x shell`, then
```
ssh-add ~/.ssh/id_rsa
```
type passhprase, receive confirmation that identity added.
Then I try connect to one of my host defines in `~/.ssh/config` file with
`IdentityFile /.ssh/id_rsa` declaration and I am asked again by the emacs about passphrase. How to solve that? Public key is properly deployed on remote host.
