Recently we moved the Sharepoint 2010 Farm server into a different physical base server. The farm has a FBA (claim based authentication) site. After moving the farm, the FBA site is not opening and giving a service unavailable http error 503. On searching various blogs for help I got the site up and running after checking the Sharepoint services in services.msc and Application Pool.
Now the issue is with FBA users logging. The error message is The server could not sign you in. Make sure your user name and password are correct, and then try again. No changes are made on the server before/after the movement. Few blogs mentions to check for the user account at IIS application pool. The already configured FBA admin account details are passed in application pool. The error is same.
Please help me with solving the issue. :)
