Using the CoreLab Membership provider (PostgreSQL) with the .NET built-in CreateUserWizard Control seems to create some problems when it comes error handling.
If the password does not satisfy the minimum length or minimum non alphanumerical characters configuration, the Provider throws an exception that is not endled by the CreateUserWizard for some reasons.
The built-in .NET provider does not behave in this way, it simply gets the user back to the user creation page with a proper error message.
Also, since the CreateUserWizard control does have an event handler (CreateUserError) and its doesn't get to it lead me to believe this is not working as intended.
