The driver supports the following authentication methods:
  • User ID/password authentication authenticates using the specified user IDs and passwords.
  • Client authentication uses the user ID and password of the user logged onto the system on which the driver is running to authenticate the user to the database. The database server relies on the client to authenticate the user and does not provide additional authentication.

  • Kerberos authentication is a trusted third-party authentication service that verifies user identities. The driver supports both Windows Active Directory Kerberos and MIT Kerberos implementations.

By default, the driver is configured to use user ID/password authentication (AuthenticationMethod=0).
