How to access to "MF Iprint Advanced Management" on a oes2018sp3 server?

How can i access over the server welcome screen to the iprint Advanced Management Console?

I have try all possibilities as admin admin.xyz and cn=admin,o=xyz also root no change!

The same problem is for User to access ther Iprint Portal?

How can help?

Thanks

The next step is to integrate the iprint appliance, in the moment i use iprint on oes2018sp3 server!

What is the big difference between the two possibilities?
