nsswitch.conf breaks IPv6 reverse host lookups

[gaige]

In the modified nsswitch.conf, the standard:

ipnodes:    files mdns dns

is replaced with

ipnodes: files ldap

which removes DNS requests for reverse lookup of IPv6 addresses. According to the comment before that line in the standard SmartOS nsswitch.conf, IPv4 lookups appear to use all sources regardless of the settings, so it seems to be a non-issue there.

Patch is to use:

ipnodes:    files ldap dns

or

ipnodes:    files ldap mdns dns

Cheers, and thanks for the kit! We are using a variant for our configurations.
