User Login Problem

Friends

Greetings

We are in ICSS B2B scenario of CRM 4.0

All the relevant XCM settings have been done and successful

When we are trying to Login on the Web through our CRM User Id, system is throwing error as invalid user id and password

We have maintained all the relevant authorizations as per the standard config guide

Please suggest me how to correct this

thanks

and

regards
