The RME server credentials are those you use to login to the RME server. If the RME server is located on the same server as Campus Manager, then just put in the admin credentials for the local server. For example, on my server rtp-main, I enter:

RME Server Name : rtp-main

RME Server Port : 1741

RME Server Protocol : http

User Name : admin

User Password : ********

That is, these are the LMS login credentials for an administrator user.
