This article describes the mandatory configuration steps for the setup of SAML SSO between BI Platform and SAP HANA with Analysis Office.

Step 1: Create OLAP Connection

  1. Open CMC and create a new OLAP connection of type “SAP HANA http”
  2. Enter the fully qualified HANA host name and HTTP port
  3. Select SSO as authentication
  4. Save the connection

 

Step 2: Create Certificate

  1. Open HANA XS Admin UI in the browser to find the name of the HANA service provider: http://<hana_host>:<hana_port>/sap/hana/xs/admin/#/samlSP (the user needs the role “sap.hana.xs.admin.roles::SAMLAdministrator”)
  2. In this example the name is S1222
  3. Go back to CMC and open “Applications -> HANA Authentication”
  4. Create new connection
  5. Enter the exact same host name and exact same port like in step 1.2
  6. Enter a name for the unique identity provider ID. You can choose a arbitrary name here. It should somehow reflect you BI Platform system.
  7. Enter the service provider name
  8. Click on the “Generate” button to generate a certificate
  9. Copy the certificate to a text file
  10. Click Ok

Step 3: Import Certificate

  1. Open the Web Dispatcher Administration UI (http://<hana_host>:<hana_port>/sap/hana/xs/wdisp/admin/public/default.html) in your browser. The user needs the role “sap.hana.xs.wdisp.admin::WebDispatcherAdmin”
  2. Go to “PSE Management”
  3. Select “sapsrv.pse” in the dropdown box
  4. Click on “Import Certificate” and paste the certificate content of step 2.9
  5. Click on “Import”
  6. After that you should see the certificate metadata
  7. Copy the content of the “Subject” field. In my example it is “C=CA, SP=BC, O=SAP, OU=BOE, CN=BIP_IDP”
  8. Restart the “webdispatcher” and “xsengine” service of your HANA server.

Step 4: Create Identity Provider

  1. Open the HANA XS Admin UI: http://<hana_host>:<hana_port>/sap/hana/xs/admin/#/samlIDP/0
  2. Create a new identity provider for your BI Platform system
  3. Enter the name of the identity provider from step 2.6
  4. Enter the subject from step 3.7 both for Subject and Issues
  5. For all other fields just enter “/”. For our use case the fields are not needed

Step 5: Assign identity provider to InA Service

  1. Navigate to http://<hana_host>:<hana_port>/sap/hana/xs/admin/#/package/sap.bc.ina.service.v2
  2. Enable SAML authentication and select your SAML Identity Provider. Important: please ensure that you only activate your SAML Identity Provider for the “sap.bc.ina.service.v2” package:

Step 6: Map the BI Platform user to your HANA user

  1. Go to HANA Studio
  2. Open your user and mark the “SAML” checkbox
  3. Click on “Configure” and Add a new mapping
  4. Select your Identity Provider
  5. Enter the name of your BI Platform user. You have to enter it case sensitive way. If your user is named “Smith” then you should enter it exactly this way. When you enter “smith” or “SMITH” it will not work later.

After all those steps the SSO procedure should work in Analysis Office. In case the SSO logon is not working the HANA “xsengine” trace contains valueable information about the root cause. In order to get all details in the trace you should set the trace level of all “authentication” components in the XSENGINE trace configuration to trace level DEBUG.

The used admin applications in CMC and HANA may look slightly different depending on your used versions.

    Christian,

    Very helpful thank you. There could be a prerequisite to enable HANA http connections in mdas.properties on the BOBJ side.

    Thanks
