When you try to use Active Directory authentication to sign in to Microsoft SQL Server from Tableau Desktop on the Mac, the following error might occur:

An error occurred while communicating with the Microsoft SQL Server Database data source '<data source name>'.
Your connection to SQL Server could not be established or was lost, most likely because of a Kerberos timeout. To renew your Kerberos ticket, close tableau and then try any of the following:
  • Lock and unlock your Mac
  • Log out from your Mac and then log in again
  • If your Local User account is different from your Active Directory account, run the following command in Terminal: knit <ADUsername@domain>. For example: kinit myuser@mycompnay.
[Simba][Support](50260) Integrated security authentication failed. (Routine Error:
Miscellaneous failure (see text)
