How to avoid ANNOYING PASSWORDS for Synaptic, Network, and so on

[asbesto]

note: FOR THE SOLUTION JUMP TO MY LAST POST HERE. Testing for 9.04

Well,

I log into MY laptop using GDM; to be more precise, I automatically log in after 10 seconds of GDM inactivity, because is my laptop, because it doesn't contain secure data, because mine is the only account in it, and because I don't care to be paranoid with my laptop.

So, for me is very ANNOYING the password request every time I launch, for example, Synaptic Package Manager, or Network config, or whatsoever the hell I want.

Is there a way to avoid all those password requesters ?!?!??!

p.s.

answers like "THIS IS BAD TO SECURITY" or "HEY 1'M A K00L K-R4D H4CK3RZ y0 dunn0 wh4t th3 h3ll 1s c0mput3rz s3kur1ty go use w1ndow$ 1nst3ad" go directly in /dev/null, garbled with urandom contents and with my blessing of a cruel death.
