Authentication Method

Attribute

AuthenticationMethod (AM)

Purpose

Specifies the method the driver uses to authenticate the user to the server when a connection is established. If the specified authentication method is not supported by the database server, the connection fails and the driver generates an error.
Important: When Kerberos is enabled, if the database user name differs from the domain user name, you are required to pass the database user name via the User Name (LogonID) option in the datasource or connection string.

Valid Values

0 | 4

Behavior

If set to 0 (No Encryption), the driver sends the user ID and password in clear text to the server for authentication.
If set to 4 (Kerberos Authentication), the driver uses Kerberos authentication. This method supports both Windows Active Directory Kerberos and MIT Kerberos environments.

Default

0 (No Encryption)
