How many services are we talking about? Is it a set number for all users, or does it vary?

If its is set then maybe the display looks like

Name    | Date    | Service1 | Service 2 | Service 3
Fred     05-06-06  PASS       PASS        PASS
George   05-16-06  PASS       PASS        PASS
Fred     05-06-06  PASS       FAIL        PASS
[download]

If there are multiple data sources, then maybe one table per data source is in order

Service1
Name    | Date    | PASS
Fred     05-06-06  PASS 
Fred     05-07-06  FAIL
George   04-05-05  PASS

or

Name    | Date    | SERVICE | PASS
Fred     05-06-06   Service1  PASS 
Fred     05-06-06   Service2  PASS 
Fred     05-07-06   Service2  FAIL
Dale     05-06-06   Service2  PASS

It all realy depends on the number of services and what you are looking for when glancing at the report. That aside I think a kind of wizard interface would be cool. First page you enter your credentials, then based on the credentials it provides you with a page for each service. Perhaps those pages even have refresher directions on accessing the specific data source, and two giant buttons PASS and FAIL. Last page takes you to the report and reminds you of the next time you need to verify your data access.
