You can enable logging on to VLF-ONE applications via Microsoft, Google or Facebook by setting the LogonHandlerId() parameter in your entry point web page (i.e. your version of web page UF_OEXEC) to LogonHandlerId(“External=Microsoft”), LogonHandlerId(“External=Google”) or LogonHandlerId(“External=Facebook”).
Refer to Optional Things You Can Do with Your Launch Component for more details including important additional configuration requirements.
