Redirecting errors in AD's Powershell module

I'm trying to write a quick script to discover things about my new domain, but I keep running into obstacles. I can't seem to find a way to suppress the error output from that module like I can in others by piping standard error (2>) to $null.

Ultimately, I'm trying to do this because this is a multi-domain forest, and I want to be able to find out which domain a user account is in easily.

Here's what I have:

$doms = get-adforest | select -ExpandProperty domains

foreach ($dom in $doms) {
    get-aduser  -Properties CanonicalName -Server $dom 2> $null | select name,CanonicalName
}

That WORKS, and shows me where the user account is, but it also spits out an error for every domain that the user name doesn't exist, and I really want to find a way to suppress that. Anyone have any tricks?

(I'm really getting sick of your crap, AD Powershell team...your module really sucks, you know that?)
