One you have a service account in /etc/passwd or NIS which has a homedir in /opt. SELinux has mistakenly seen this as a login account, because the account has a UID > 500 and a valid shell. If you change the shell to /sbin/nologin or /bin/false and run genhomedircon, the duplicate file context will go away.
That was totally correct. I have some non-fedora packaged software installed there (created by a self made RPM). Changing the shell got rid of the issue. I wonder if they still work though ;).
