KRB5 May Be Edited
This property appears by default in the library configuration file for the LDAP mechanism. You can manually add it to the TdgssUserConfigFile.xml for other supporting mechanisms, if needed. See About Editing Configuration Files.

Editing Guidelines

  • You should specify a value for LdapGroupBaseFQDN if the AuthorizationSupported property for the mechanism is set to yes.
  • For best results, set the value of LdapGroupBaseFQDN to the FQDN of an object one level higher in the directory tree than the highest level group object that maps to Teradata Database external role objects.
  • If you do not edit the default value for this property (“”), LDAP uses the value of the LdapBaseFQDN to search the directory, however, because LdapBaseFQDN is deprecated, this approach is not recommended.
  • Edit this property on database nodes and on the Unity server, if used. Also see Coordinating Mechanism Property Values.
