Domain user not allowed to login in Zorin system

Please help!! I am trying to login with domain user into my zorin system which is already joined in domain, but it prompting error message"Sorry, Password authentication error, Please try again" I have tried all possible method even tried to manually add domain user in GUI Users setting, but it is only resolving my username but not accepting the password. Please let me know if anything needs to enable at Domain Controller.

Could it maybe a Problem with the Keyboard Layout?

Is there any chance that the user has changed their password recently, and the system is caching an old password that is causing this effect? Sometimes removing a user profile then re adding , if this were a case, can sometimes fix the error.
