Problem using gitlab-ce and gitlab-runner

I've failed on running job by gitlab-runner from local machine using ssh-executor.

Meanwhile I can run git clone git@mygitlab.myserver.com, so as I think it's ok with my ssh setup. But when I try to run job using same machine as gitlab-runner it failed with error:

Using SSH executor...
GitLab: Disallowed command
ERROR: Job failed: Process exited with: 1. Reason was:  ()

In my gitlab-shell.log:

gitlab-shell: Attempt to execute disallowed command <$'bash' $'--login'> by user with key

My GitLab components:

GitLab 9.3.6
GitLab Shell 5.1.1
GitLab Workhorse 2.1.1
GitLab API v4
Git 2.13.0
Ruby 2.3.3p222
Rails 4.2.8
postgresql 9.6.3

gitlab-runner:

Version:      9.3.0
Git revision: 3df822b
Git branch:   9-3-stable
GO version:   go1.7.5

Hope you can help me. Thank you!
