restBuilder with search endpoint to return messages with admin privileges?

Hi djondinium 

I tried it and it seems to be working for me. I copied your code (minus sorts and constraints) and tested it in stage with a normal non-admin user and I could see the names.

<#assign query = {
  "messages": {
    "fields": [ "id", "subject", "author.id", "author.first_name", "author.last_name" ]
  }
}>

<#assign comments = restBuilder().method("POST").path("/search").body(query).admin(true).call()>

<#list comments.data.items as message>
    <p>
        ${message.subject} by ${message.author.first_name!"missing"} ${message.author.last_name!"missing"}
    </p>
</#list>

Here is what I see with a regular account. Maybe ask support.
