what is the user ID and passward for SAP service marketplace?

Hi all,

--Do anyone know what is the userID and passward for the SDE.SAP. When I went to this website:

http://help.sap.com/saphelp_nw04/helpdata/en/8f/c08b3baaa59649e10000000a11402f/frameset.htm, it asked me for the userID and passward and I typed my userID and passward from SDN.SAP website. However it doesn't work.

Any help will be appreciate. Thank you.
