As described in my previous post, I had the Problem, that the People Picker did not show/find users of 2-way trusted domains, which worked in SP2010 out of the box. I´m still trying to figure out if it´s a bug or a feature. 😉
The solution/workaround that MS-Support presented was a little bit unsatisfying …
Peoplepicker-searchadforests: Stsadm property (Office SharePoint Server)

So I created a script that hopefuly makes life easier for many of you, who already have to think about too many things when creating webapplications.
It just needs to be run once and can be execute on any server. (automatically retrieves the 2-way trusted domains and applies the settings to all webapplications)
Solution for 1-way trust not implemented (needs username and password for remote domain)
It´s not perfect, so feel free to enhance it where needed.
