The directory should be LDAPv3-compliant. See Certified Directories .
Verify that the LDAP mechanism is enabled on all Kerberos clients, on all Vantage systems to which they connect and the Business Continuity Manager server, if used. Set the LDAP mechanism as the client default, or the user must specify it at logon.
The directory username used at logon must match a Teradata Vantage username. For acceptable logon username forms, see Logging on Using Sign-on As .
The matching Vantage username must have LOGON ... WITH NULL PASSWORD privileges. See Working with User Privileges in Teradata Vantage .
The LDAP AuthorizationSupported property must be set to no in TdgssUserConfigFile.xml on the Teradata Vantage system, and in TdgssBcmConfig.xml on the Business Continuity Manager, if used. See Changing the TDGSS Configuration .
