Hi,

I am testing find a standard config for Linux authentication against Active Directory and I am testing with Centos 6. I have decided on a SSSD/Kerberos/LDAP configuration as described in RedHats "Integrating Red Hat Enterprise Linux 6 with Active Directory" section 6.3.
http://www.redhat.com/rhecm/rest-rhecm/jcr/repository/collaboration/jcr:system/jcr:versionStorage/ae40084d0a052601783f1ea42715cdef/26/jcr:frozenNode/rh:resourceFile

It works very well but for the one domain in our forest i.e. b.domain.org. However, users of other domains in the forest can not be authenticated. 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.

Scenario I would like to implement;



I have attached my current config files as a reference. They work for a single domain rather than the whole forest. I suppose I am stuck whether to add each AD child domain as separate domains in SSSD and REALMS in kerberos or if I can get it to see the whole forest.


Thanks for any help / pointers,


Matthew
