Accidental exposure of something else in
cn=KDC,cn=$FQDN,cn=masters,cn=ipa,cn=etc. My fear comes from the fact
that in order to make this work we have to expose stuff in
cn=KDC,cn=$FQDN,cn=masters,cn=ipa,cn=etc to apache. These kind of cross
-domain security allowances always raises red flags for me.

Don't cross the streams... it would be bad. :)
