The environment consists of a one-way trust relationship, I have no problems adding users from the local domain, however I can only add a few select users from the domain that the trust is setup for. This appears to be the case for only one site collection,
as a previous site collection can authenticate to and add users from this other trusted domain.
I have checked the following article in order to authenticate objects in the other trusted domain, but it appears to have not helped.
What steps should I verify so that I can add users to given stie collections?
