I just tried to reproduce this in Ubuntu 12.10 but could not.
I clicked "Network | Edit Connections..." to open "Network
Connections". I selected the "Wireless" tab and selected a non-active
connection name. I clicked "Edit..." to open "Editing <connection-
name>". In the "IPv4 Settings" tab I set "Method" to "Automatic (DHCP)
addresses only"; I entered address "8.8.8.8" in the "Additional DNS
servers" field; I entered a domain name in the "Search domains" field
and clicked "Save..." The search domain name and address did not appear
in /etc/resolv.conf, even after I restarted network-manager.
Andrew, are these the same steps you took?
Also, are you sure that you did not at some point add the search domain
name and nameserver address to /etc/network/interfaces or to one of the
files in /etc/resolvconf/resolv.conf.d/?

Title:
Nameserver address entered for one connection gets added to
resolv.conf for all connections
Status in “network-manager” package in Ubuntu:
Incomplete
Bug description:
Hello, I have several WiFi networks with the option "saved for all
users" enabled on my laptop, meaning the config files are written to
/etc/NetworkManager. I use DHCP on all these networks, but one of them
has a misconfigured AP that assigns an incorrect DNS server; I've set
that one network to assign addresses only via the connection editor,
and inserted the required DNS info myself for said connection.
Here's the problem: my /etc/resolv.conf adds this manually added DNS
server and the search domain in front of any and all other DNS servers
that dhcp provides no matter what other network I've connected to.
This basically breaks my DNS.
I'm running 12.04.1 LTS on a 64-bit machine, no mods to the system or network
stack, pretty much a pristine install.
Network manager is 0.9.4.0-0ubuntu4.1
If there are any tests or info you'd like, please let me know.
Here is a copy of resolv.conf while connected to a network whose DNS
is supposed to be the router (192.168.2.1), edited for privacy:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 134.74.***.***
nameserver 192.168.2.1
