We have a search policy at the Organization where most of the users are
located. Under that Organization, there are Servers OU, workstation OU
and Users OU which also holds some users. Our search policy is set as
selected container--> the OU where most of the users are
search level-->-1

But somehow, the users at Users OU are unable to log in unless to change
the context to users.organization.

Is there any way that the users at users OU and at the Organization can
both be able to log in?

Please advise!

Thank you very much!
