Unable to take machine off network - user cannot sign in

We have one of our users who is trying to take their macbook off the domain. When they take their macbook and establish it on a network that is not our own, they cannot get signed into their computer. The machine will error stating incorrect username or password while off the network

We attempted to setup active directory through  the general settings area of Jamf Pro, we established “Directory Bindings”, entered our domain information. The computer OU format of OU=OU1,OU=OU2,OU=OU3,DC=DC1,DC=DC2 and went into “User Experience” and ensured “Create Mobile Account at Login” was checked. 

Now I am not sure what else I missed in setting up the domain or which settings we need to enable so our user can take their device offsite. I do not want to remove the configuration/enrollment from the device or create a local account. Does anyone have any suggestions?
