I have already done this but it is still not work. is it possible that you will share the policy. I have shared the policy that i have configure as attached file. Could you please help me solve it
That is not what I meant when I said "join the mwg to both domains".
What you did is create multiple authentication rules. This will not work and actually is causing your problem.
Go under Configuration > Windows Domain Membership and join the MWG(s) to all domains you like.
