Question How to reset directory permission for entire installation?

[Chris85]

Hi all,
today, I've mistakenly changed ownership of the entire /opt/* directories where my plesk installation is located.

My Plesk is working again so far, but i cant find details what directories have to be owned by root:root / rootsaadm / psaadmsaadm etc.
Now I'm searching for details how to rebuild the ownership of all the plesk directories.

I've ran plesk repair which fixed some perm. issues and now tells me all is ok, but i still see permission issues.
Is there any script available that properly sets permissions?

Thanks
-Chris
