network-manager-openvpn ignores dhcp-option SEARCH

[pdf]

network-manager-openvpn (or some upstream component) is ignoring the dhcp-option SEARCH parameter, which means that not only won't additional domains get appended to search, but if 'Use only for resources on this connection' is enabled, those domains will not get resolved via the VPN DNS servers, breaking split-horizon DNS for sites with more than one domain. When 'Use only for resources on this connection' is enabled, the domains enabled in dnsmasq should be a union of dhcp-option SEARCH, dhcp-option DOMAIN, and reverse domains for networks routed via the connection. Currently only the latter two are enabled.

Without 'Use only for resources on this connection' enabled, all DNS resolution does appear to go via the VPN servers, but this is not necessarily desirable, and creates a situation where users may be wedged between having their DNS work as expected, and having their routing work as expected.

Thank you for your bug report, could you try if that's still an issue in current versions, especially with the fix for bug #1624317 or bug #1754671
