The following example is a typical XML document received from the default driver configuration.
<nds dtdversion=”1.0” ndsversion=”8.5”> <source> <product build="20050509_1030" instance="SAP-USER-REMOTE-46C" version="1.0">Identity Manager Driver for User Management of SAP Software</product> <contact>Novell, Inc.</contact> </source> <input xmlns:sapshim="http://www.novell.com/dirxml/drivers/sapusershim"> <modify class-name="US" event-id="O_001_0000000000216097" src-dn="SSAMPLE" timestamp="20030509"> <association>USdJSMITH</association> <modify-attr attr-name="PROFILES:BAPIPROF"> <remove-all-values/> </modify-attr> <modify-attr attr-name="USERNAME:BAPIBNAME"> <remove-all-values/> </modify-attr> <modify-attr attr-name="ACTIVITYGROUPS:AGR_NAME"> <remove-all-values/> </modify-attr> <modify-attr attr-name="PROFILES:BAPIPROF"> <add-value> <value>SAP_ALL</value> <value>SAP_NEW</value> </add-value> </modify-attr> <modify-attr attr-name="USERNAME:BAPIBNAME"> <add-value> <value>JSMITH</value> </add-value> </modify-attr> <modify-attr attr-name="ACTIVITYGROUPS:AGR_NAME"> <add-value> <value>SAP_EMPLOYEE</value> </add-value> </modify-attr> </modify> </input> </nds>
Some characteristics to note:
All XML documents received from the SAP system are translated into <modify> documents. This translation occurs because it is not possible to determine whether the object described by the document has been modified or is new. Additional modification or translation of the document is accomplished through policies and the Metadirectory engine.
The <modify> element contains the classname of the object described in the SAP namespace (that is, US=User). The event-id attribute contains the IDoc number from which the data is derived. The src-dn attribute contains the SAP Object name value. The timestamp attribute contains the date that the IDoc was processed by the driver.
The <association> element data always contains the format USd . Usernames in SAP are always uppercase.
The <modify-attr> element contains the attr-name described in SAP format (Structure or Table name:Attribute Name).
Because multivalue attributes cannot be consistently mapped across systems, the <remove-all-values> element is used prior to all <add-value> tags on Publisher channel documents. This instructs the Metadirectory engine to remove all existing values for the attribute prior to assigning the new values. If this functionality is not desired, one of the policies can be used to modify the document.
All values are in a string format.
All values for DirXML-locSapRoles and DirXML-locSapProfiles require that you set two fields in SAP. In order to map from a single string value to a structured format, default policies use a colon “:” delimiter in the Identity Vault values (such as ADMCLNT100:SAP_ESSUSER), which are then transformed to (or from) the SAP structured format. The Schema Mapping policy indicates the structure components to set for these values.
