Identity & Access Management products and customers - a list

A common question from people interested in the Enterprise Identity & Access Management space is "which customers use this product"? So I thought I'd take a step towards helping figure this out.

I've compiled a list of products and the customers using them. This is not a full list. It is simply one I compiled using publically available information on the web. Each entry in the list should have a link to the relevant article I found.

I'll have a permanent link on the right side of my blog so it's always available. I figured it was better than relying on people having to dig up this post to get to the list everytime (unless you've bookmarked the list directly of course).
