Taxonomy link to organic group throws Access-Denied

Hello out there,

I wanted to group the Organic groups to form a higher hierarchy above the OG. I do not need anything like permission nesting, so Taxonomy feels like a good solution.

But I encountered a problem. Here is what I tried step by step:
- installed the taxonomy-menu and menu-block modules.
- created a taxonomy and entered some terms.
- referenced some Organic groups to some terms.
- created a menu block containing this taxonomy and let it display on front page

So far so good. The block with the menue created out of the taxonomy does show up. Clicking on one term gives a list with all the groups that hold this term.

BUT: when clicking on any shown group in the result list, it wants to send me to the group by referencing to the ID, like: website.com/node/26

This throws an error as it seems like that Organic Groups can not be accessed by Node-ID directly. (well at least not in my setup)

Can anybody confirm this? Does anybody have an idea how to solve this?

I'm new in Taxanomy and also to Organic Groups so any hint or advise is highly appreciated.

Thanks everyone, gb5256
