I followed this blog: http://blogs.visigo.com/chriscoulson/configuring-forms-based-authentication-in-sharepoint-2013-part-1-creating-the-membership-database/
and I'm at the point where I can add users using the FBA pack, I can see them in the SQL database, but everytime I try to login with FBA I get "The server could not sign you in. Make sure your user name and password are correct, and then try again."
I can login with Windows Auth just fine. I read in another post that this meant my STS config wasn't configured correctly. Well I've looked that thing up and down numerous times, side to side with my machine.config and I don't notice anything unusual.
I added this to the sts.config but I think I would need help reading the logs if the answer lies there.
<serviceDebug includeExceptionDetailInFaults="True" httpHelpPageEnabled="True"/>
Much help is appreciated. (sharepoint 2013 btw)
SOLVED: A default provider was required for this particular setup to work. I was advised that this solution will prevent having multiple providers, but luckily we didn't need that.
<membership defaultProvider="FBAMembershipProvider">
<roleManager defaultProvider="FBARoleProvider">
