7.1.1 Filter Publish Options

Setting attributes in the filter to publish specifies which classes and attributes are published from the SAP system to the Identity Vault.

The default driver configuration publishes the following User class attributes in the filter.

7.1.2 Filter Subscribe Options

Setting attributes in the filter to subscribe specifies which classes and attributes are synchronized from the Identity Vault to the SAP system.

The default driver configuration subscribes to the following User class attributes in the filter:

7.1.3 Schema Mapping Policy

The Schema Mapping policy is referenced by the driver object and applies to both the Subscriber and Publisher channel. The purpose of the Schema Mapping policy is to map schema names (particularly attribute names and class names) between the Identity Vault and the SAP User database. Any modification or removal of existing entries in the Schema Mapping policy could destroy the default configuration and policies processing behavior. Adding new attribute mappings is discretionary.

The following class mapping is included with the default driver configuration:

The User class is configured to synchronize bidirectionally between SAP and the Identity Vault. A change made in one system will transfer to the other system.

All attributes in the Publisher and Subscriber filters should be mapped unless they are used only for policy processing.

SAP User field values can be arranged in three types:

The following table includes common attribute mappings for the User class and their descriptions, assuming that only the primary piece of structure communication data is required (such as ADDTEL:TELEPHONE). If fields of a table are to be mapped, you should specify only the Table name in the mapping (such as LOCACTIVITYGROUPS). If you do this, the driver generates all table field values in structured format. For more information, see Section F.0, Structured Format Examples. On the Publisher channel, the structured data must be transformed to string format.

The default mappings for the driver are as follows:

7.1.4 Input Transform Policy

You modify the Input Transform policy to implement your specific business rules. The Input Transform policy is applied to affect a transformation of the data received from the driver shim.

The policy is applied as the first step of processing an XML document received from the driver shim. The Input Transform policy converts the syntax of the SAP attributes into the syntax for the Identity Vault.

The default driver configuration includes two rules that perform the following functions:

7.1.5 Output Transform Policy

You modify the Output Transform policy to implement your specific business rules. The Output Transformation policy is referenced by the driver object and applies to both the Subscriber channel and to the Publisher channel. The purpose of the Output Transformation policy is to perform any final transformation necessary on XML documents sent to the driver by Identity Manager.

The default driver configuration:

7.1.6 Publisher Placement Policy

The Publisher Placement policy is applied to an Add Object event document to determine the placement of the new object in the hierarchical structure of the Identity Vault.

The Placement policy places all User objects in an Identity Vault container that you specify during installation. You can also modify this location by using the Publisher User Placement Global Configuration Variable (GCV.)

The default driver configuration:

7.1.7 Publisher Matching Policy

The Publisher Matching policy is applied to a Modify Object event document. Matching policies establish links between an existing entry in the Identity Vault and an existing entry in the SAP system. The Matching policy attempts to find an existing object that matches the object generating the event by the criteria specified in the policy.

The default driver checks for matches based on the sapUsername attribute. A fallback policy is also provided that checks for matches on the Given Name and Surname attributes.

7.1.8 Publisher Create Policy

The Publisher Create policy is applied when a new object is to be added to the Identity Vault. The default driver configuration:

7.1.9 Subscriber Matching Policy

The Subscriber Matching policy is applied to a Modify Object event document. Matching policies establish links between an existing entry in the Identity Vault and an existing entry in the SAP system. The Matching policy attempts to find an existing object that matches the object generating the event by the criteria specified in the policy.

The default driver checks for matches based on the values of the Given Name, Surname, and sapUsername attributes.

If you do not have an association in your query, the SAP system performs a full table scan of the user table. This might cause a long delay in receiving a reply from the matching query.

If the specified user name is known in SAP, adding an association value reduces the query to a single object. You can use the following Output Transformation policy to add the association.

<rule>
<description>Add association value to matching queries</description>
<conditions>
<and>
<if-operation op="equal">query</if-operation>
<if-xpath op="not-true">association</if-xpath>
<if-xpath
op="true">search-attr[@attr-name="USERNAME:BAPIBNAME"]/value</if-xpath>
</and>
</conditions>
<actions>
<do-append-xml-element expression="." name="association"/>
<do-append-xml-text expression="association">
<arg-string>
<token-text xml:space="preserve">USd</token-text>
<token-upper-case>
<token-xpath
expression='search-attr[@attr-name="USERNAME:BAPIBNAME"]/value/text()'/>
</token-upper-case>
</arg-string>
</do-append-xml-text>
</actions>
</rule>

7.1.10 Subscriber Create Policy

The Subscriber Create policy is applied when you want to add a new object to the Identity Vault. The default driver configuration:
