Hello Sir/Madam,

I unable to connect CRM using following command using C#

connectionString=" AuthType=ClientSecret; url=xxxx.crm5.dynamics.com; ClientId={Application (client) ID}; ClientSecret={ClientSecret}"

CrmServiceClient svc1 = new CrmServiceClient(connectionString2);

because it's encounter this issue "LastCrmError = "Invalid Login Information : The HTTP request was forbidden with client authentication scheme 'Anonymous'.\r\nThe HTTP request was forbidden with client authentication scheme 'Anonymous'. => The remote server returned an error: (403) Forbidden.Unable to Log..."

Can you able to assist us about this issue?

Hi,

Have you created the Application User in Dynamics CRM and assigned security role.

If above step is pending you will get error and will not be able to connect to crm.
