I've been following the steps outlined in section 7.3.5 of the manual entitled
Integrating OpenShift Enterprise
with Identity Management (IdM)
in Red Hat Enterprise Linux
OpenShift Enterprise 2.1
IdM in Red Hat Enterprise Linux 7
Windows Server 2012 - Active Directory Integration
I now have our RHEL V7 running IdM, setup as an IdM Server in a domain, Realm
and subnet
different from our existing AD server running Windows 2008 R2 with a populated
user database
that can be queried using ldapsearch and can authorize users.
I have successfully created a domain trust between the RHEL V7 Server
(linux.ipa.cxo.cpqcorp.net 10.20.0.59/24) and the AD Server
(win2008.osn.cxo.cpqcorp.net 16.112.240.55).
To simplify the configuration I have no firewall running and so have stopped
both iptables
and firewalld.
All steps in section 7.3.5 have been followed. But when I run the first test
for a user
on the AD system, the system is unable to find anything:
[root@linux ~]# getent group 'OSN\Domain Users'
[root@linux ~]#
[root@linux ~]#
[root@linux ~]# getent passwd 'OSN\ldap25'
[root@linux ~]#
I find this in the krb5kdc.log file:
Oct 07 16:28:01 linux.ipa.cxo.cpqcorp.net krb5kdc[12908](info): AS_REQ (6

I'm not quite sure what else I'm missing or have not understood in order to
query the
AD server from the linux IdM server...but it would appear that something is not
correctly
defined in the krb5.conf file found below:
[root@linux ~]# cat /etc/krb5.conf
includedir /var/lib/sss/pubconf/krb5.include.d/
[logging]
default = FILE:/var/log/krb5libs.log
kdc = FILE:/var/log/krb5kdc.log

osn.cxo.cpqcorp.net = OSN.CXO.CPQCORP.NET
[dbmodules]

}
Any help greatly appreciated.
