What are the services that needs to be activated in SICF in order to access the tcode SOAMANAGER?

Currently i am getting the message below

No switch to HTTPS occurred, so it is not secure to send a password

SSO logon not possible; logon tickets not activated on the server

Choose "Logon" to continue A dialog box appears in which you can enter your user and password

No switch to HTTPS occurred

Any input to solve this will be helpful.
