pnpm: Not working with private registry

We are using private registry for npm modules based on artifactory.

I have global config for npm in ~/.npmrc like this:

_auth = {auth-key-here}
email = {e-mail}
always-auth = true
registry={link-to-private-registry}

when I run pnpm install I’m getting something like this:

  ERROR Registry returned 401 for GET on ...

pnpm version: 0.64.8

Additional information:

• node -v prints: v6.5.0
• Windows, OS X, or Linux?: macOS Sierra v10.12.3
