kcctpl_create_connections failure

[Daniele Dario]

Hi all,
I have two samba4 DCs both Version 4.0.0alpha18-GIT-95c514a.

kdc01 is the one where I provisioned the domain and also acts as DNS
(bind 9.9.0b1 and dlz plugin).

Yesterday I joined the second one (kdc02) to the domain but looking in
the logs of kdc02 I see

[2012/01/20 09:46:35,
1] ../source4/dsdb/kcc/kcc_topology.c:1402(kcctpl_color_vertices)

while in kdc01 no.
