  • TDNEGO now supports JWT (JSON web token) authentication.
  • New LdapServicePasswordFile property.
  • The DIGEST-MD5 authentication protocol used by LDAP is deprecated.


  • With the addition of JWT, Teradata Vantage now supports a greater variety of authentication protocols and mechanisms.
  • The LdapServicePasswordFile property provides a way for you to change the LDAP service password without requiring a system restart.


  • If you use the LdapServicePasswordFile property, the LdapServicePassword and LdapServicePasswordProtected properties are ignored, and passwords are read exclusively from the password file.
  • Passwords listed in the LDAP service password file must be encrypted using the tdspasswd command-line utility.
  • Teradata strongly recommends you stop using DIGET-MD5, and instead use simple binding with TLS protection. A future release of Vantage will remove support for DIGEST-MD5.
