I was attempting to assign some permissions to Active Directory groups and ran into an issue where groups with spaces or the # sign in them. The engine log contained messages like these

2013-05-22 08:39:35,228 WARN [org.ovirt.engine.core.bll.SearchQuery] (ajp--127.0.0.1-8702-134) ResourceManager::searchBusinessObjects - erroneous search text - ADGROUP: name=#Virtual Engineering

The group name is valid. The example above contains both the space and #, but trying groups with just a space and others with just a # also fail. I was able to successfully add groups that contained characters and -. Has anyone else had an issue like this?
