Authentication Method - secSAPR3

Hello,

I am in the process of developing a customized businessobjects application using the BOBJ sdk. I have created a portal which allows the default authentication types like - secEnterprise,secWinAD, secLDAP. I got to understand that secSAPR3 is not a supported authentication type by the BOBJ Enterprise SDK.

Can somebody please help me out on how a secSAPR3 authentication could be achieved so that my application could use the SAP authentication type. I did check out the 'BusinessObjectsu2122 XI 3.0 Integration for SAP® Solutions Java SDK Guide' but was not of any help.

Thanks,

Vishal
