[Samba] SAMBA4 - Domain Trust lost and not recreate

[Chris Fischer]

Hi Folks,

my S4 AD works well since the end of december. (Thanks to Christmas)
I also managed to create the incoming trust to an Windows 2008 Srv 
domain. Now the trust is broken. I tried the old reboot trick and so on.

My last (stupid) idea was to delete the trust on both sides and recreate 
it using the management tools from Microsoft. But the creation fails on 
the samba4 site, complaining about an still existing trust to the 
destination domain.

Where is the domain trust stored and therefore, how can i manually 
delete it?

Thank in advance

Chris
