Your claws will bypass the same DR as your weapons normally would, with the added bonus of whatever animal form you are in. Ex. +1 Adamantine Scimitar bypasses Slashing, Magic, and Adamantine DR. In animal form your attacks will now bypass all of the above in the addition to piercing for wolves and bludgeoning for bears.

I know, it's a very old thread, but for anyone looking this up for the first time, the keen effect from weapons are STILL (5 years later!) not being applied to druid wild form attacks. For those who are curious, I tested this on my lvl 5 toon with an item whose keen effect is otherwise most definitely working properly, a tiefling assassin's blade (keen effects in the updated cannith crafting system are buggy, so I avoided those for testing). In wolf form (level 2), you usually crit on a 19 or 20; with a keen weapon it should be 17-20 ("base critical threat range of this weapon is doubled"), but I still only crit on a 19 or 20 (and no, not an 18 either). It didn't matter whether I equipped the weapon and then changed into wolf form, or equipped it while already in form.

Thanks for the clarification--someone earlier in this thread explicitly tested for that, and it didn't work either. I now have IC: bludgeon, so can't test Impact weapons personally to see if it was ever fixed.
I necroed this thread because after 8 years of DDO I'm running my first dronk build and everything I read before rolling it up (including this thread) said that keen was supposed to work in animal form. When I searched for info on the forums on this topic, this thread came up first, so figured I could pay it forward.
While I'm at it: probably not news either, but stunning fist no longer works in wolf or bear form, even if you're wearing handwraps (or nothing); doesn't matter whether you equip them before or after taking animal form. Updated ddowiki to reflect this.
It's a pity that there is usually no official list of answers for questions like this, or it's scattered across various release notes, not to mention that many things that are supposed to work--but are well known not to--aren't in the Known Issues list. Even ddowiki, which I otherwise love and try to help with, is often outdated (as it was this time).
