Interesting. I wouldn't have thought that running an SSO integration is that painful. I've done it before, albeit for a single enterprise client, and while annoying at first, after delivery was just like another feature.

The real issue is not the first one, the issue is the 2nd and 3rd, and 10th, will all have some minor idiosyncrasy. There are other posts in this thread that discuss it more in depth - I have only enough personal experience to know that this particular stove is hot.
