This bug is created as a clone of upstream ticket:
Currently, we decide whether to ID range of posix type or not depending on the presence of the AD users with POSIX attributes set in the root domain.
However, we do not properly handle the case if the users are defined in a non-root domain of the forest.
Thank you taking your time and submitting this request for Red Hat Enterprise Linux. The request was cloned to the upstream tracker a long time ago (see link to the upstream ticket above), but it was unfortunately not given priority either in the upstream project, nor in Red Hat Enterprise Linux.
Given that this request is not planned for a close release, it is highly unlikely it will be fixed in this major version of Red Hat Enterprise Linux. We are therefore closing the request as WONTFIX.
To request that Red Hat reconsiders the decision, please reopen the Bugzilla with the help of Red Hat Customer Service and provide additional business and/or technical details about it's importance to you. Please note that you can still track this request or even offer help in the referred upstream Pagure ticket to expedite the solution.
