No, but if you get is working let me know.
I asked for SAML support... let me see... Coming up on FIVE years ago: Jun 28, 2012: Support SAML
aside from that you would have to get integrated IIS authentication working, and then have that pass the right stuff into Solarwinds, and hope that works.
I've not had time to play with this to get it working, and our production instance is running slightly behind the release curve right now
(We will need to get an OS upgrade in the works soon, and that is going to affect the timing of upgrades)
You or anyone get this working by chance? We're looking into trying to do the same thing
