The reason why my machines are
in different subnet is that 1 box is in
Gothenburg and the other is in Malmö, 300 km away from each other. :) Have
to "build" a new box in Gothenburg and try to vampire, then they will be in
the same subnet. Gonna take a while because I am alone at my department
today... :(

Log file looks a little bit strange just before the failure.
For some reason, your PDC doesn't return what is expected in RootDSE.

Another thing I've noticed is that your machines are in different networks.
Why is that?
PDC is in 10.242.10.xxx, and it seems the machine you are
vampiring with is in 10.242.101.xxx network.
I don't know what the exact problem
Samba may experience because
of this though. Just a note.

What I suggest is:
I will do a little bit more testing on my machine to see if there is
a bug with RootDSE searches (now I notice, that in log I've got from
Aaron few days ago, RootDSE contains duplicated attribute values, so
it seems there is a bug here)

In the meanwhile, could you check what RootDSE search gives you
against your PDC?
In case you don't know, you may do this by running something like:
> bin/ldbsearch -H ldap://pdc.gbg.inputinterior.se -b '' -s base
"objectclass=*"
> bin/ldbsearch -H ldap://gbg.inputinterior.se -b '' -s base
"objectclass=*"

And also, could you please try re-vampiring with the two machines in
same network?
