Computer Configuration > Policies > Centrify Settings > Mac OS X Settings > Network > Legacy location settings > Configure Proxies > Bypass Proxy settings for these Hosts & Domains
Specify fully-qualified host names and domains for which you want to bypass proxy settings.
You should use this policy to define the hosts or domains that should never be contacted by proxy.
To use this policy, click Enabled, then click Add, type a host or domain name, and click OK to add the entry to the Show Contents list.
Each host or domain should be listed as a separate line in the Hosts and Domains list. For each host or domain, click Add, type the host or domain name, and click OK to add the host or domain as a new entry in the list. When you are finished adding items to the list, click OK to close the policy dialog box.
This policy can take effect dynamically at the next group policy refresh interval without rebooting the computer.
