We just moved to a VPS server and the auto-update feature of WordPress has stopped working without manually inputting connection information everytime.

I found this article: http://www.chrisabernethy.com/why-wo…nnection-info/

that seems to show some light on the situation.

The question is this:
if we are running as user ‘nobody’ now, what should we change it to to make this work? and how should it be set for new accounts on our VPS?
