Hello!  
I’m using Bedrock with Capistrano deploys.  
When I use command `bundle exec cap staging deploy:check` I get an authentication error :

```
...

cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as deploy@SERVER_IP: Authentication failed for user deploy@SERVER_IP
Tasks: TOP => git:check => git:wrapper
```

Capistrano could not connect to ssh-agent on my server.

But I can log in on my server via SSH like this `ssh deploy@SERVER_IP` without password. I dit all the instructions in [Capistrano Authentication & Authorisation Docs page](http://capistranorb.com/documentation/getting-started/authentication-and-authorisation/), so I can use command like me@localhost $ ssh [deploy@one-of-my-servers.com](mailto:deploy@one-of-my-servers.com) ‘hostname; uptime’.

If I enter command `ssh -A deploy@SERVER_IP 'env | grep SSH_AUTH_SOCK'` I get result

```
SSH_AUTH_SOCK=/tmp/ssh-UweQkw7578/agent.7578
```

Here is my deploy.rb file :

```
set :application, 'dyxovka-special'
set :repo_url, 'git@github.com:tanzoor/dyxovka-wp-theme.git'
set :branch, :master
set :tmp_dir, '~/tmp'
set :log_level, :info
set :linked_files, fetch(:linked_files, []).push('.env')
set :linked_dirs, fetch(:linked_dirs, []).push('web/app/uploads')
```

Here is my staging.rb file :

```
set :stage, :staging
set :deploy_to, -> { "/var/www/vhosts/project/dev" }
server 'SERVER_IP', user: 'deploy', roles: %w{web app}
set :ssh_options, {
  user: 'deploy',
  keys: %w('/c/Users/alexander/.ssh/id_rsa'),
  forward_agent: true,
  auth_methods: %w(publickey),
  verbose: :debug
}
fetch(:default_env).merge!(wp_env: :staging)
```

Apache’s agent forwarding agent instruction is enabled in sshd\_config file : `AllowAgentForwarding yes`

What should do with my config files to make my deploy work?

Windows 8.1  
Ruby 2.2.0  
Capistrano 3.2.1  
Git Bash

Try following this [article](https://developer.github.com/guides/using-ssh-agent-forwarding/) as well as it has some tips about SSH forwarding set up/debugging.
