Requirement :- Login Customer community user into Salesforce using Partner WSDL.
I tried solution provided here and it works for customer community users for me using SOAP UI.
But when I used partner wsdl and the c# code shared in Salesforce examples for customer community users, I am getting error : An unexpected error has occurred: INVALID_LOGIN: Invalid username, password, security token; or user locked out.
The same code is working for Salesforce User license users, I am able to get session id for Salesforce user License successfully.
Is there any API login issue for customer community license?
