We are facing an odd issue in our Prod Env.
We have a site collection and a subsite under it with broken inheritance.
I create a FBA user, give contribute permissions to the user for the subsite ONLY.
The user doesn't have any rights on the root site.
I get access denied even on the subsite even though he has access to it. This only happens if the FBA feature is turned on.
Any idea why it could be happening?
