We just recently upgraded our servers to RHEL 7 and our perl scripts are no longer working. When I run the code below, I'm able to retrieve the root services document for our ccm server, but when I attempt to retrieve the catalog, I get a response telling me that authentication is required again. I run the same code on a different server that is still running RHEL 6 and the script runs perfectly. Why does this script no longer work?
