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.
Valid Values
0 | 4
Behavior
If set to 0 (User ID/Password), the driver uses user
ID/password authentication. The driver supports the SCRAM-SHA-256 hashing mechanism. During
connection, the driver determines whether to send the password in hashed form or clear text
based on the server settings.
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 (User ID/Password)
