# Property Mappings Property Mappings allow you to pass information to external Applications. For example, pass the current user's Groups as a SAML Parameter. Property Mappings are also used to map Source fields to passbook fields, for example when using LDAP. ## SAML Property Mapping SAML Property Mappings allow you embed Information into the SAML AuthN Request. THis Information can then be used by the Application to assign permissions for example. You can find examples [here](integrations/) ## LDAP Property Mapping LDAP Property Mappings are used when you define a LDAP Source. These Mappings define which LDAP Property maps to which passbook Property. By default, these mappings are created: - Autogenerated LDAP Mapping: givenName -> first_name - Autogenerated LDAP Mapping: mail -> email - Autogenerated LDAP Mapping: name -> name - Autogenerated LDAP Mapping: sAMAccountName -> username - Autogenerated LDAP Mapping: sn -> last_name These are configured for the most common LDAP Setups.
