To configure LDAP for authentication and authorization requires the following:
Because the user is authorized by the directory the directory username does not need an equivalent database username, as is the case for an authentication-only implementation
The procedure for configuring mechanism property values in the TdgssUserConfigFile.xml is shown in Making Changes to the TdgssUserConfigFile.xml on Database Nodes.
You must also map directory users to other directory objects to define user database privileges in the directory. See Provisioning Directory Users with Teradata Schema Extensions, or Using Native Directory Schema to Provision Directory Users.
