Yealink RPS with Autoprovision Password

[Corey]

We were recently provided with a login for Yealink RPS. Our security policy requires that we use HTTPS and an autoprovisioning password with digest authentication.

What I am looking for is a way to set the following two settings on RPS to allow the devices to authenticate against our autoprovisioning server:

auto_provision.server.username
auto_provision.server.password

How is this accomplished using RPS? I have read through the VAR manual and cannot find any information on how or where such parameters are configured.

Thanks!
