You never "use" an entityID. You set it in the software and
communicate metadata that contains this. It's a name, nothing else.
You can easily seet his when you change your entityID to a URN, since
these do not "resolve" to anything (without special systems).

What does "access the DS page" mean, specifically? You'll need to
access a SAML service provider, which in turn may redirect you to a
DS, which (with SAML2) will redirect you back to the SP, which in turn
will issue a SAML authentication request to the IdP, which then might
ask you to authenticate and will then send you off the SP with a SAML
protocol message.
So without an SP there's no authentication request and there's nothing
for the IdP to do after authentication.

But none of this should have anything to do with the content of the
string of the entityIDs used.
