Blackberry disabled server certificates query

Hi We are testing various deivces with our new eduroam wirelss and so far so good. However, an issue cropped up with blackberrys where during the setup, if you leave the box unchecked "disable server certificate validation" then the blackberry connects fine if you uncheck connection fails "failed to connect". I have checked other institutions and they have conflicting guides some say leave it checked others say uncheck. Can anyone advise the status - to check or uncheck?
