I just installed SharePoint 2013 for the company I work for. I installed the FBA Pack and then disabled the Windows Authentication. Then while still logged in with the windows account I could access the new FBA settings and added myself as a user. I closed
all browser windows and reopened the main site to log in with the new account. I was able to log in but when I went to the Site Settings, the FBA Settings were gone. Now I can only log in with the one user. I can turn windows auth back on from central admin
so users can log in, but that defeats the purpose. I tried requesting access but no matter what group I associated the user with, I still couldn't see the settings.
I'm guessing I need to make the new user a site collection admin but every time I try to add it i get the error "No exact match was found. Click the item(s) that did not resolve for more options." Oddly, it doesn't accept the domain accounts either,
I have to click cancel. Maybe there are some powershell commands that can accomplish this?
UPDATE: I modified the machine.config file according to this guide
and the People Picker recognized the FBA username. I changed the owner to my new account successfully, but it killed the
sharepoint app. I deleted the edited machine.config and restored the copy I made and sharepoint works again. My account can now see the FBA settings but the people picker doesn't work on central admin.
