Hi, we are using FBA Pack with SP2013 Foundation. Solutions was working all the time. But now, several users are unable to log in:
The server could not sign you in. Make sure your user name and password are correct, and then try again.
Reset password without success. tried to deactivate the user and got the following error:
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
The statement has been terminated.
This error matches the users that are not able to log in. Thought about duplicates in the database, but the user is unique.
