The driver supports the following authentication methods:
- No authentication authenticates using the user ID of the default Teradata database when no security mechanism is selected.
- Teradata 1/Teradata 2 authenticates using TD1 or TD2 database system username and password. This mechanism is available on all supported client and server platforms.
- LDAP uses LDAP (Lightweight Directory Access Protocol) is a directory information service that allows you to centrally store information and authenticates using LDAP entries.
- Kerberos is a trusted third-party authentication service that verifies user identities. The driver supports both KRB5 and KRB5C implementations.
- NTLM authenticates clients to the database through a challenge-response authentication mechanism that enables clients to prove their identities without sending a database password to the server. The driver supports both NTLM and NTLMC implementations.
Note: Kerberos and NTLM
are enabled through the Teradata client. Refer to Authentication mechanisms in your Teradata documentation for
requirements.
By default, the driver is configured to use no authentication (SecurityMechanism=<empty string>).
