Directory Configuration 
SAP Sourcing users are authenticated against a directory. A Directory object is a logical directory mapped to a physical directory, which is typically an LDAP implementation. The directory configuration also identifies the mapping of attributes from the LDAP directory that are synchronized with the local User object.
A cluster configuration can support a single buy-side directory and a single sell side directory. To support multiple directories, you must define multiple cluster configurations (for details, see Maintaining a Cluster Configuration). Each configuration will have a separate external host name.
This section describes how to create and edit a directory configuration.
