Looks like you have a negative result on the NSS query for that user
Several questions to ask here....
You posted in the Express forum, are you working with the freemium version of the product? (I ask because sometimes folks that are using the commercial version post here too)
What happens when you do an `adquery user -A qwertyuiop` ?
Can you tell me the OS/version and show me the passwd line of the /etc/nsswitch.conf file?
Does this happen in some or all systems?
Is your AD normalized? (e.g. is there a quertyuiop in another domain in the forest)
What happens when you rebuild the cache (adflush --force) and wait?
Thanks!
