The previous example showed a simple CUA environment where the Central system distributed User data only to the driver’s logical system. This is not a typical environment. In most CUA environments, a Central system distributes data to SAP Child logical systems on multiple application servers.
A small example of a typical CUA landscape looks more like this:
Figure 8-4 A Central System Distributing Data to SAP Child Logical Systems on Multiple Application Servers
As in Figure 8-3, the driver can set the distribution of User account information to the additional CUA Child systems by setting the tab for them. However, the real power of the driver is realized when you use access controls to the various SAP clients based on the driver’s policies. For example, all employees can receive employee Self-Service rights on the HR system, but an employee identified as an HR Administrator could also be granted rights to the HR administration functions. The following example shows a Create Style Sheet template for setting the tab for logical system ADMCLNT100 and DRVCLNT100, setting the SAP_ESSUSER Role on logical system HR1CLNT100, and setting the SAP_ALL Profile on logical system ADMCLNT500. (In Identity Manager 3, this policy is implemented through the Policy Builder.)
<xsl:template name="add-cua-auths"> <!-- Sample CUA distribution settings. - Central SAP system is ADMCLNT100 - Child SAP systems are: ADMCLNT500 and HR1CLNT100 - Driver's logical system is DRVCLNT100 --> <add-attr attr-name="DirXML-sapLocRoles"> <!-- In a CUA environment, set driver's LS name with a blank role. This allows the driver to receive events from SAP. --> <value> <xsl:value-of select="'DRVCLNT100:'"/> </value> <!-- Setting the target LS name with a blank CUA role allows the User object to log on to the target child system but receive no rights. --> <value> <xsl:value-of select="'ADMCLNT100:'"/> </value> <!-- The third value shows how to set a 'real' CUA role for a child logical system. This causes distribution from the Central system to the child system and sets the Employee Self-Service role. --> <value> <xsl:value-of select="'HRCLNT100:SAP_ESSUSER'"/> </value> </add-attr> <!-- Example of setting a 'real' CUA profile. --> <add-attr attr-name="DirXML-sapLocProfiles"> <value> <xsl:value-of select="'ADMCLNT500:SAP_ALL'"/> </value> </add-attr> </xsl:template>
NOTE:The driver also provides the ability to directly connect to a CUA Child. To enable the driver to connect to Child logical systems, set the SAP Client Type option to CUA Child during driver configuration. For more information, see ‘Driver Parameter’.
