impersonation 'Identification' is incorrect

impersonation 'Identification' is incorrect, should be 'Impersonation'; This is the message in the GatewayErrors.log with a datasource configured to use 'SSO via kerberos for directquery queries'

Re: impersonation 'Identification' is incorrect

@ACV,

Do you connect to SQL Server in Power BI Desktop? What is your gateway service account and SQL Server service account? 

Please make sure that you have configured all steps following the guide in "Configuring Kerberos Constrained Delegation for the gateway and data source" section of this article.
