Start NetworkManager on boot, not after login.

Hello ....
I have one small problem.
Specifically, on a desktop computer at work, I use openSUSE and
Yast -> Network Settings -> Global Options -> Network Setup Method
I selected "Traditional Method with ifup"
My computer has been added to the Windows domain and everything works beautifully.
For a desktop computer is not problem that ifup is selected because it's connected with wire.



I've installed openSUSE on a laptop and initially I also setup settings like desktop computer
and all my work when my laptop is plugged in via the cable network.
However a problem is with wireless device.
If you add wireless via ifup-a, then Internet is not working,
but domain normally work and i have rights that have as a domain user.
If in Yast -> Network Settings -> Global Options -> Network Setup Method
I select "User Controlled with NetworkManager" that creates problems.
Now I have the KDE NetworkManagement widget to select the wireless and Internet is working, there is a problem with the domain.
When "User Controlled with NetworkManager" is selected then neither LAN or WLAN did not work during boot.
And it occurs to me that when I log on with a domain account, then my username is taken from the cache from laptop, and does not find the domain and i don't have rights as domain user because the network just fallen upon boot.
What interests me: How can I get the "User Controlled with NetworkManager" settings works on boot so i can login with domain user and not with the account from the cache?


Well, I hope I was clear. :-)


PS: I was looking for some solutions already on the net, but all we tested did not work. :-(
