SSO for EP using LDAP

Hi Experts,

I have followed the help link [SSO for EP using LDAP|http://help.sap.com/saphelp_nw2004s/helpdata/en/43/4bd58c6c5e5f34e10000000a1553f6/content.htm]. I have followed the given steps. Eventhough, It's not going to the portal while we enter the url. What could be the problem?

Please, help in this regard.

Regards,

Venkatesh. K
