Use Kerberos and Kerberos Delegation

To authenticate user access to a MATLAB^® Production Server™ instance, you need to configure Kerberos. To delegate a client’s credential to a next hop web server or a database server that is protected by Kerberos, you need to configure Kerberos Delegation. Configuring Kerberos and Kerberos Delegation requires domain administrator privileges. Currently, you can use Kerberos and Kerberos Delegation with MATLAB Production Server instances running on Windows Server^® operating systems with a Windows^® Key Distribution Center. To configure Kerberos and Kerberos delegation, consult your IT / Windows System Administrator, and follow these steps:

• Set up a service account for the MATLAB Production Server and register a service principal name for MATLAB Production Server service instance.

• Configure constrained delegation without protocol transition for the service account.

• Configure the local security privilege for the MATLAB Production Server service account.

• Enable Kerberos and Kerberos Delegation in the MATLAB Production Server configuration file (main_config). For more information, see http-authentication-method and client-credential-delegation.

Only the following MATLAB functions within a deployable archive (.ctf) support using Kerberos Delegation:

• webread

• webwrite

• HTTP Interface (MATLAB) functions

• Database Toolbox™ functions (requires an ODBC driver)

All other functions within a deployable archive (.ctf) are executed using the credential of the MATLAB Production Server instance.
