Are authentication and SSO connected with LDAP user data synchronization (LDAP Connector, LDAPMAP)?
No. Since SAP Basis 4.6, SAP systems have had an LDAP Connector, which allows connection to an LDAP directory. However, only individual accesses to the LDAP directory are possible in this version. Data synchronization between SAP R/3 and the LDAP directory was standardized with SAP Web AS 6.10, and mass synchronization is possible. The data synchronization applies only to user and role data, however. Authentication and SSO functions are provided neither using the LDAP Connector nor through transaction LDAPMAP. For information about transferring an external authentication to the LDAP directory, see Is it possible to connect products from external vendors to implement authentication and SSO outside the SAP system?.
