Importing hierarchical entitlement data in OIA - part 3

Just as I explained in my previous blog entry I will discuss importing account and entitlement information from Oracle Health Insurance (OHI) Back Office (BO) into Oracle Identity Analytics (OIA). The OHI BO application is used by healthcare insurers/payers and supports the administrative processing of member data and claims, as well as the product data (including the brands and available distribution channels) and healthcare procurement data required for this type of processing.

More important I will use the <attributeValue> / <attributeValueRef> element pair in the XML data to be imported into OIA so entitlement data can be defined once and referred to many times from the account data. In this particular case this is very useful since OHI Roles are referred to many times from several accounts.

OHI BO's entitlement data consist of OHI application Roles that contain zero or more so-called 'Moduleautorisaties' (Module Authorizations). This means we deal with hierarchical entitlement data. Similar to what I described in my previous blog entry I have used Talend ELT tool to extract the entitlement data (via SQL) from the OHI database and write these to XML files to be imported in OIA.

For more information about this ELT job design please contact me. Anyhow, in the last step I write the output into XML as can be seen from the first lines below (several elements are expanded '-' and other elements are collapsed '+'):

 <?xml version="1.0" encoding="UTF-8"?>
-<rbacx>
    <namespace namespaceShortName="OHI" namespaceName="Oracle Health Insurance"/>
   -<attributeValues>
      +<attributeValue id="Role_BHCC_0001">
      +<attributeValue id="Role_BHPA_0001">
      +<attributeValue id="Role_BHTP_0001">
      +<attributeValue id="Role_DOORSTART">
      +<attributeValue id="Role_DVWZVNTST_ROL">
      +<attributeValue id="Role_GBTP_OVIZA">
      +<attributeValue id="Role_GBTP_TUSSENP1">
      +<attributeValue id="Role_GEBRUIKER_ROL">
      +<attributeValue id="Role_INMAUT001">
      +<attributeValue id="Role_INMAUT002">
      +<attributeValue id="Role_MANAGER_ROL">
      +<attributeValue id="Role_OPENZORG_ROL">
      +<attributeValue id="Role_OPL MERK OPL">
      +<attributeValue id="Role_SCRIPTS">
      +<attributeValue id="Role_XYZ">
    </attributeValues>
   -<accounts>
      +<account id="AADOULI">
      -<account id="ABRUIJN">
         -<name>
             <![CDATA[ABRUIJN]]>
          </name>
          <endPoint>OHI</endPoint>
          <domain>Production</domain>
         -<attributes>
            -<attribute name="Role">
               -<attributeValues>
                   <attributeValueRef id="Role_DOORSTART"/>
                   <attributeValueRef id="Role_INMAUT001"/>
                   <attributeValueRef id="Role_MANAGER_ROL"/>
                </attributeValues>
             </attribute>
          </attributes>
       </account>
      +<account id="ALAKERVE">
      +<account id="ASIEGERS">
      +<account id="BGLAZEMA">
      +<account id="BLAAK">
      +<account id="BLAGEMAA">
...

As can be seen from these lines all the OHI application Roles are defined in the first <attributeValues> element section. These Roles are then referred to in the <accounts> element section below that, completely compliant with the schema file accounts.xsd as shipped with OIA.

Finally, all the OHI account and entitlement data is then imported into OIA (just as the accompanying glossary data) and correlated to the global users. An example of how the data can be examined within OIA can be seen in the picture below:

Have fun, René!

Importing hierarchical entitlement data in OIA - part 2

In my last blog entry I talked about importing hierarchical entitlement data into Oracle Identity Analytics (OIA). Today I want to discuss another example regarding Microsoft Windows shared files and folders permissions and show how easy these data can be transformed and imported in OIA for either attestation and / or auditing purposes.

All of the data is represented in two input files. One file containing an AD users export and the other one the file and folder permissions:

File #1 containing AD users adusers.csv is as follows:
(metadata: DN|CN|memberOf|sAMAccountName|displayName|sn|givenName):

CN=Rene Klomp,CN=Users,DC=domain,DC=com|Rene Klomp|CN=datagroup,CN=Users, DC=domain,DC=com;CN=homegroup,CN=Users,DC=domain,DC=com|renek|Rene Klomp|Klomp|Rene
CN=John Doe,CN=Users,DC=domain,DC=com|John Doe|CN=datagroup,CN=Users, DC=domain,DC=com;CN=homegroup,CN=Users,DC=domain,DC=com|johnd|John Doe|Doe|John
...

File #2 containing files and folders permissions shares.txt is as follows:
(metadata: share;group;permission):

home;homegroup;FULL CONTROL
SYSVOL;Everyone;READ
SYSVOL;Administrators;FULL CONTROL
SYSVOL;Authenticated Users;FULL CONTROL
data;datagroup;FULL CONTROL
NETLOGON;Everyone;READ
NETLOGON;Administrators;FULL CONTROL
...

This time I have used the tool 'Talend Open Studio for Data Integration' to join these two input datasets and transform the data into the right XML format for importing it into OIA. In Talend you design a Job which is made out of several components and a flow related to the data going through these various components. The Job I designed for these particular datasets is rather straightforward and easy to understand as can be seen in the screenshot below (by right-clicking on the image you should be able to examine it in the original size).

Within Talend Open Studio I start with two tFileInputDelimited components, each reading one of the two files. The 1st file adusers.csv has a memberOf attribute which is a multivalued attribute. It can contain a list of groups each separated by a ';'. Therefore the next step after reading this file is normalizing the data for the memberOf column using the tNormalize component. Next thing we need to do is joining both datasets. For this I have used the tMap component.

As you can see it is pretty straightforward to connect the input stream / attributes to the output stream / attributes and do the join based on a simple expression (just as a trivial example - group in input file shares.txt needs to be in memberOf in file adusers.csv).

Now that both sets are joined we can transform the data and write to XML.For that I have used the tAdvancedFileOutputXML component which writes the output in an intermediate XML file (in this case: out.xml). Again, pretty straightforward to define the structure and looping and grouping of elements as you can see in the picture below. The schema is still rather arbitrary but I will use XSLT to transform this into the right schema for OIA in the next step.

For that last step in the ELT transformation process I use the tXSLT component and an appropriate XSL Transformation file (in this case: AD_01_accounts.xsl). It picks up the file that was written in the step before, transforms according to the transformation defined in the XSL file and finally writes the output to our final AD_01_accounts.xml file.

If this whole process ends succesfully there is one more step that I have added. This is using the tXSDValidator component in Talend to check the result against a predefined schema. In this case I obviously use the accounts.xsd schema file as shipped with OIA (in this case version 11.1.1.5.0). As you can see in the first picture this validation process also ends successfully and ends with outputting '[job AD] File is Valid'.

Now we are ready to import this XML file into OIA - of course we have to configure a namespace for this particular resource first. This whole exercise took me less than 20 minutes to setup and finish!

All the files mentioned above can also be downloaded in this single package: data.zip. If you open the files individually in a browser by clicking on one of the links above, be sure to look at the source or save the file and open in an XML or other editor... otherwise the browser might just show you some blank page or a page with little information.

Have fun, René!

PS. I have formatted the final AD_01_accounts.xml document using XmlPad so it is easier to read than the default output which is not using any formatting at all - this is obviously just a visual thing for this blog and not needed for importing.
