This is understandable as I have pointed all the config files at the child domains DC's, i.e. dc1.b.domain.org rather than dc1.domain.org. I have been searching for example configurations which will authenticate any user in the forest even though the Linux installation is joined to a different child domain but not found any.

Hi Matthew,

this feature is only supported starting with 1.10 upstream..

Even on RHEL-6 I would recommend trying out the AD provider, not the
AD/Kerberos provider combo.
