Some users are unable to connect, because they have a hostname mismatches with the server name. This is similar to SSL/TLS web browser warnings, when the domain typed doesn't match the certificate presented.
This should be corrected on the server by the server admin. However, some users may not have access to the server.
I would even add "(not recommended)" to the name of that setting..
