Sure - there isn't a way to avoid this, except to use seperate IP
addresses. If we could use a stock KDC, then we would have. I'm sure
an enterprising programmer could probably make Heimdal load the PAC
generating plugin, and an AD-compatible hdb backend (because that's what
we do internally anyway), but then it's not a stock KDC any more.
Fortunately the services linux clients require of a KDC is a subset of
those our modified Heimdal provides.
We bundle the KDC because given the high degree of linkage required, we
felt it was easier to have it 'just work' than the traditional linux
nightmare to setup Kerberos and LDAP. (We also have an internal
implementation of kpasswd).
LDAP is a much more difficult question - windows client require the AD
schema be loaded,and while we have a project to allow us to map Samba4's
requirements onto standard-ish LDAP schema (on an external LDAP server),
we have no choice but to present an AD-like view to AD clients such as
