dns.servers

This configuration parameter specifies a space separated list of IP addresses of DNS servers that are used to resolve domain controller names. Set this parameter if a computer running Mac OS X 10.7 or later cannot connect to a domain controller through a VPN connection.

Starting with Mac OS X 10.7, /etc/resolv.conf is no longer used for domain controller name resolution. Therefore, some VPN programs no longer update DNS server information in /etc/resolv.conf when signing on. On computers running Mac OS X 10.7 and later, this can result in the computer not being able to connect to a domain controller through a VPN if the DNS server locations are not specified as described here.

The following example shows the setting of two IP addresses for DNS servers:

dns.servers: 111.22.333.4 555.66.777.8
