Hi,
I'm not aware there is documentation from Siteminder side for SAP Enterprise Manager integration.
From Siteminder perspective, we cannot prevent other third party product from integrate with Siteminder. In that case, the other product need to provide documentation on how to perform the integration as well as what version they supported to perform the integration. If you are following SAP documentation to perform the integration, I think the question asked best to address by SAP.
However, if the documentation is from CA, please let me know where you download the documentaion so I can trace back the source.
P.S not sure what is Siteminder Manager, I presume is component within SAP Enterprise Manager?
Hope this helps.
