Active Directory Integration error after server move

[sunflower]

I moved my Nagios XI install from a stand alone to a VM and moved from a 32 bit OS install to a 64 bit OS install.
I am using the Active Directory Integration Component with the same settings as on the previous server. I changed the IP address to match the old server. I installed the same version of nagiosxi that I am currently using.

64 bit Centos 6.4
Manual install on VM
Active Directory Settings:
Account Suffix, BaseDN and Domain controllers are exactly as on the other server.
Security is none.
Listed 3 DCs and all resolve.

I have uninstalled and reinstalled the Active Directory Integration component. My DNS is correct.

Consistently get "Invalid username or password". No errors in httpd/error_log.
AD showing no errors. Tried using IP address instead of names for the DCs. Still doesn't work.

Any help would be appreciated.
