Legal SAP training

Hi,

One of my friend wants to start training institute and planning to conduct training courses on all sap modules with his company legally. I told him that private trainings on SAP are not legal, may be need to take authorization from SAP AG. But he told me that Lot of people / companies are giving SAP trainings legally but they mentioned in their website that their company has no affiliation with SAP AG and they are taking IDES server access from SAP.

Is it true, i had a strong feeling that private trainings are not legal but even his points also made me to think. Please clarify us.

Thanks

Sri
