Let us learn more about the feature sql server bulk insert kerberos delegation. With the support of our MSSQL support services at Bobcares let us take deep dive in to the feature and how to set it up.

What is sql server bulk insert kerberos delegation?

This is a feature that allows us to use the Bulk Insert command while authenticating with Kerberos delegation to give data into a SQL Server table from a remote source.

When accessing resources on a distant server, Kerberos delegation allows a user to impersonate another user. This is useful when using the Bulk enter statement to enter data into a SQL Server table from a remote source that requires authentication using a different set of credentials than the ones used to connect with SQL Server.

To use the Kerberos delegation functionality, we must first setup the SQL Server service account to use Kerberos authentication. Then we have to establish a constrained delegation in Active Directory.

How to setup sql server bulk insert kerberos delegation?

The general procedures for configuring Kerberos delegation for SQL Server are as follows:

1. Set up Kerberos authentication for the SQL Server service account. Setting up a Service Principal Name (SPN) for the SQL Server instance and registering the SPN with Active Directory are both important.
2. In Active Directory, create a restricted delegation to allow the SQL Server service account to delegate credentials to the remote data source.

   This entails setting up a delegation trust between the SQL Server service account and the remote data source, as well as describing the services and protocols that may be utilized with the delegation.
3. FInally, In the SQL Server properties, check the “Enable Kerberos Authentication” box.

Once Kerberos delegation is setup, we can specify the Kerberos authentication settings using the “WITH” clause in the Bulk Insert statement, as seen below:

In this example, the “WITH” clause includes the “KERBEROS_DELEGATION” option to allow Kerberos delegation for the Bulk Insert operation.
