If you are experiencing the error ‘Unable to login to Dynamics CRM’ while generating the CRM Proxy class using CrmSvcUtil tool, you should try this to resolve it.

There is a new command parameter added to the CrmSvcUtil tool : interactivelogin:true

You may append this command parameter to your CrmSvcUtil command line and this would give you a pop up to enter the credentials and would sort the above mentioned issue.

Your command would look like:

CrmSvcUtil.exe /url:<Server url>/<Organization> /username:<username> /password:<pwd> /domain:<domain> /out:”Xrm.cs” /namespace:Xrm /serviceContextName:CrmContext /interactivelogin:true

 

Interactive Login popup window:
