Connecting with Windows authentication from a non-windows +machine +

+

Kerberos is used by Active Directory, you need to have the +appropriate packages installed on your client machine. For MacOS, the +Kerberos packages are usually already installed. On Linux, you’ll have +to install krb5-user. Most of this setup comes from this +site.

+
    +
  1. +

    On the non-windows client machine, create or update +/etc/krb5.conf so that it points to your AD server. Here’s +an example of krb5.conf:

    +
    [libdefaults]
    +default_realm = DOMAIN.COMPANY.COM
    +
    +[realms]
    +DOMAIN.COMPANY.COM = {
    +  kdc = dc-33.domain.company.com
    +}
    +
  2. +
  3. Run kinit <username>@DOMAIN.COMPANY.COM to get +a ticket granting ticket from the kerberos domain controller (KDC). +(NOTE: you want to make sure your KDC is accessible from your +machine)

  4. +
  5. Download the latest MSSql +JDBC driver.

  6. +
  7. +

    Try to connect to the database with the following code in +RStudio:

    +
    library(devtools)
    +library(DatabaseConnector)
    +connectionDetails <- createConnectionDetails(
    +  dbms="sql server", 
    +  ...
    +  extraSettings="authenticationScheme=JavaKerberos")
    +c <- connect(connectionDetails = connectionDetails)
    +

    In RStudio, you should see that the variable c has a value and the +new connection in the connections tab as well.

    +
  8. +
+

Note: If you are getting the below error on Mac:

+
+

Error in rJava::.jcall(jdbcDriver, “Ljava/sql/Connection;”, +“connect”, : com.microsoft.sqlserver.jdbc.SQLServerException: Kerberos +Login failed: Integrated authentication failed. +ClientConnectionId:13fb0d4e-4822-4de2-a125-8408334cb3ed due to +javax.security.auth.login.LoginException (Cannot get any of properties: +[user, USER] from con properties not available to garner authentication +information from the user)

+
+

Instead of kinit you can also try +/System/Library/CoreServices and find ‘Ticket Viewer’ Click +‘Add Identity’, then enter your user name. After you click ‘Continue’, a +Kerberos ticket should have been generated.
