secSAPR3 SAP authentication in IOMS 2010

Hello...

I am reading in the "Integration Option for SharePoint Installation and Administration" guide http://help.sap.com/businessobject/product_guides/sbo41/en/sbo41_ioms_admin_en.pdf

and it says the following:

The integration option for SharePoint software supports the following authentication modes in a Business

Intelligence (BI) platform deployment:

• Enterprise

• Lightweight Directory Access Protocol (LDAP)

• Windows Active Directory (AD)

Is it true that it does not support SAP authentication as it is not listed above! What can be done enable SAP users to logon as they do using BO LaunchPAD?

And if it is not possible how can the web.config file have this entry to modify?

<!-- You can specify the default Authentication types here -->

<!-- secEnterprise, secLDAP, secWinAD, secSAPR3 -->

Thanks for answering.
