Hello,

AtriumSSO is indeed a bit of a tease.  It's an open source product
called OpenSSO that was killed off by Oracle after they purchased Sun.

The first tease is the idea that AtriumSSO provides SSO.  AtriumSSO
doesn't provide an Active Directory SSO implementation which is what 90%
of AR System users want from an SSO product.  This means you can't open
IE, navigate to Midtier and sign in without being prompted for
credentials.  To be fair, there is "half" of an AD implementation in
OpenSSO.

BMC's documentation states the product is not fully supported.  On page
12 of their documentation it states, "Defects requiring time and
resources beyond commercially reasonable effort might not be
addressed.".  This is an entirely acceptable position given OpenSSO is
about 650Mb of code and libraries, and the BMC additions account for <5%
of the code, so they can be forgiven for not having reviewed/tested the
other 95%.

You can purchase support from a company called ForgeRock, created after
Oracle killed off OpenSSO.  I've spoken to them and believe they can
help with some of the 95%, but won't be able to help with AR System
configuration and deployment.

AtriumSSO is installed as a separate Tomcat instance, introducing more
administrative requirements. 

AtriumSSO has no "wizard" to integrate with your corporate
infrastructure, which means you'll require BMC consulting days to
perform the task.  I assume customers are required to pay for BMC
professional services.

AtriumSSO is not recommended for external SSO use.  On page 20 of their
documentation it states, "Installation of BMC Atrium SSO on an external
Tomcat server is not recommended due to security and load issues".

AtriumSSO has no support for the Windows User Tool, which is entirely
acceptable given the WUT is being dropped (but we know that many AR
System administrators love it!).

OpenSSO was designed as a corporate SSO solution to take on the likes of
Novell Access Manager, Cleartrust and Siteminder.  It was never designed
to slip neatly into the Midtier to solve the SSO problem.

I don't believe there's support for an IIS front end either.  I searched
for IIS in the Atrium SSO documentation and couldn't find a match.
