Cannot 'Use Windows Session Credentials' or login after ESX 6 joined to domain

[it_jacob]

So we are having this issue where after joining a domain successfully, this ESX standalone box will not let users login via vsphere, either by manually entering credentials or choosing use windows session credentials.

Despite the permissions being in place, for example a user and the domain admin account has been added with all permissions over the physical host, you get this error when attempting to login:

We have attempted to leave the domain and join again, however the issue is persistent.

Any ideas?

Thanks!
