You can combine authentication towards an external user directory (such as LDAP directory or a Windows NT domain) with adding users manually to the Spotfire database.

This can enable users to access Spotfire even though they are not part of the external user directory. For example, there may be temporary users that you do not want to add to the LDAP directory, or you may want to ensure that administrators can access Spotfire if the connection to the LDAP directory is lost. These users will be added to the same domain as the users created in Spotfire.
