You can identify the source datastore for the service provider (SP) channel configuration in the PingFederate administrative console.
PingFederate supports PingDirectory, Microsoft Active Directory, Oracle Unified Directory, and Oracle Directory Server as source user repositories for outbound provisioning. However, you can use other types of LDAP servers, either identifying them as Generic or registering them with PingFederate. For more information, see the sample.template.txt in the <pf_install>/pingfederate/server/default/conf/template/ldap-templates directory.
Information from your user-datastore is used to supply mapped values for each user attribute required by the service provider (SP).
