Help me find a robust OpenID 2.0 provider!
We're looking at various SSO solutions for our organization, and I would like to suggest OpenID as a viable option, since (a) there is good consumer support in a number of web applications, and (b) it's simpler to implement than Shibboleth, which is the alternative technology.  However, this requires that we find a robust OpenID provider, ideally one meeting the 2.0 specification.
The only solutions I've come across so far are:
Atlassian Crowd
This looks great, although the $4000 price tag may make it a tough sell.
Community-ID
This looks like an interesting idea, but I'm not sure the project quality is at a suitable level (yet).  In particular, it's not clear if LDAP support actually works (which will be a requirement in our environment).
Have you implemented OpenID in your environment?  What are you using?  Have you selected an alternative SSO technology?
