Supporting non-Kerberos LDAP with simple authentication and no DNS
integration would significantly decrease the work required for people
like Dennis.  Instead of having to set up Kerberos and DNS and an LDAP
provider that integrates with both, he could just set up a very simple
LDAP server and use a physically secured network or SSL with
self-signed keys to protect his authentication traffic.

There are already LDAP servers that use simple backends, including an
OpenLDAP variant that uses /etc/passwd and /etc/shadow instead of a
db.  If the requirement for Kerberos and DNS directory integration
were removed, and simple authentication worked, you would be able to
support pretty much anything out there in the linux/unix world.

That way oVirt wouldn't have to reinvent any wheels, and people like
Dennis would have significantly less costly and time-consuming
rebuilding of their networks to do before being able to implement
oVirt.
