cross forest trust with one way trust issue

Hi All,

I have  2 seprate forest abc.com and xyz.com

Recently I did create the one way incoming trust from abc.com - xyz.com  and outgoing trust from xyz.com - abc.com using the trusts password.

But notice that when I try to give permission to one of the folder of xyz.com domain by selecting abc.com domain, it's prompted me users name and password? Is it the correct way to work after creating the one way trust.

Also passing the username and password for abc.com domain at the prompt but still it's fail with below error.
