iPad Pro + Laptop to Windows Domain

One of my client’s employees wants to connect both his iPad Pro, and his company laptop to the domain to be able to access the server from both. First off, is it even possible to add an iPad Pro to a Windows domain? Secondly, I didn’t setup home folders, instead opting for their files to be saved locally per my client’s request. With this being the case, how would one go about having a single user use the same account on two separate devices, assuming of course, that it is possible to connect the iPad Pro to the Windows domain at all? Should I create a home folder for that one user?
