Domain User Unable to Login on ADManager Plus Server

Dear All,

I'm using the evaluation version of ADManager plus 6.1 but after configuring the Domain Controller & Domain Name, domain users are not able to log on the server following error display to them

For Input String: "False"

Please try again

What I did wrong ? someone point out me to the correct direction. 

Thanks
