Currently I have upgraded a number of my 3040s to 9.1.2101 and I am able to login to a Horizon session using the domain short user name e.g ad\jsmith but when I try to login using the full domain username e.g email@example.com it comes up saying wrong account or password. I have applied the domain settings under “login experience\login settings” but still unable to access. We do not experience this issue with 8.6.710, we are running Horizon 7.12. Any guidance would be appreciated. David.
