In my setup, our domain is “domain.loc”
My Active Directory Defaults settings, under Other -> Fog Settings in the Web UI are:
FOG_AD_DEFAULT_DOMAINNAME: domain.loc
FOG_AD_DEFAULT_OU: [blank]
FOG_AD_DEFAULT_USER: domain\username
FOG_AD_DEFAULT_PASSWORD: [FOGCrypted password]
Also, make sure the account you are using is a member of the domain group BuiltIn\Account Operators, is a member of Domain Admins, OR has been delegated rights to add, delete, and manage computer accounts in the default “Computers” container and any other container in which you want to create computer accounts. I think there is a 10 computer limit on normal accounts adding computers to the domain.
