IDM and EP

Hello Experts,

I am new to SAP IDM. However i am aware and I work in SAP EP.

I am confused about SAP IDM.

Please help me out. I have following queries:

1) EP has user management feature, then why IDM?

2) Are EP and IDM completely different products?

3) Advantages and disadvantages of IDM over EP.

Thats all.

Thanks,

Yogesh
