The error we caught said '407 "authenticationrequired"' during module install behind proxy

[Arvind P R]

I read at a number of places that if my puppet master is behind a proxy which requires authentication 

puppet module command does not work

despite setting the global parameters 

http_proxy, https_proxy on bash the command throws an error

[root@centos-razor ~]# puppet module install saz/dnsmasq --force

Notice: Preparing to install into /etc/puppetlabs/puppet/modules ...

Notice: Downloading from https://forge.puppetlabs.com ...

Error: Could not connect to https://forge.puppetlabs.com

  There was a network communications problem

    The error we caught said '407 "authenticationrequired"'

    Check your network connection and try again

setting the values http_proxy_host and http_proxy_port inside puppet.conf doesnt help either, as there is a no way I can set username and password there.

Is there a workaround for this?
