Forest1 and forest2 are in a unidirectional trust. Forest1 is the trusting domain and forest2 the trusted domain.
I am the administrator of forest1. Forest1 has a ressource that need to be accessible from forest2.
Forest2 is an independant company. Forest2 has a group of users that need access to the ressource in forest1.
I wanted to grant said group permissions to said ressource. However, when I try to search the active-directory of forest2, I am asked for the password of administrator@forest2.
How am I able to add the group from forest2 to the ressource in forest1, if I do not have access to forest2?
