Aaagh excuse my typo in the subject line
When I couldn't get the linux build to work in the DMZ, we moved it back into the network for testing purposes.
The error is something along the lines that it couldn't connect to the ldap service using the account provided (not a work at present so can not check). I will check how I've set up the DNS when I get back tomorrow, but I think it's fine. As far as LDAP goes, the settings are all IP so DNS shouldn't be a problem.... I would think; just really frustrating that the windows build worked lol
