i’ve followed the instruction on the following link:
Configuring Forms Based Authentication in SharePoint 2010
when user logged in: if the username and the password is wrong a message is appear to notify the user to try again
but when the username and the password is right an exception is thrown:
[FaultException`1: Unexpected exception occurred, please contact administrator to resolve this issue.]

finally i found the solution, it was because an error in the role provider in web.config , the CN value was wrong
