Hi Community of K2 Users,

We are currently in the early stages of using K2 in our environment.  We have many custom systems using a Custom SQL/ASP.NET membership provider.  We would like the communities thoughts on the integration of existing ASP.NET Membership Providers? 

Has anyone implemented existing membership providers specifically OAUTH or ASP.NET providers? If so, what were the pain points?  Pros & Cons? How well does K2 handle the mixed mode providers?  Are the users stored in K2 Custom SQL User Manager tables?  Is an OAUTH provider a more manageable method of authentication?  How is the upgrade paths?  Any feed back would be appreciated.

Thanks,

JF
