Hello,
I was trying to do a test install of zimbra on a vps machine and was running into the ldap initalization error (28160)

The internal ip for the vps is 10.1.3.4
the external is 173.199.***.***

I originally tried the split DNS with bind and could not get it to work. I then tried with dnsmasq, which is still installed and am receiving the same error.

Any help is appreciated.

Sean
