Comment 9 for bug 203593

I figured out what i did wrong on this, and it may help others so here it is..... When trying to connect my ubuntu box to my workgroup I edited the domain in which it was trying to log on. Here's my screenshot as an attachment. When it returns the error sudo: unable to resolve host <username> it was trying to query my PDC, not the local machine. easy fix is take out the domain changes, and check to make sure your loopback is configured to your machine name (the 127.0.1.1 entry in SYSTEM>ADMINISTRATION>NETWORK>(HOST TAB)).
