Hello Altaf Ingar ,
The login failure occurred because the user did not have the required Virtual Machine User Login role on the session host. This role is necessary for AVD authentication. In some cases, administrators may also need the Virtual Machine Administrator Login role for elevated access.
Assign the required role(s) to the user on the VM resource (session host).
Steps:
- Go to Azure Portal → Virtual Machines → [Your VM] → Access control (IAM).
- Click Add role assignment.
- Select one of the following roles based on the requirement:
- Virtual Machine User Login (for standard user access)
- Virtual Machine Administrator Login (for admin-level access)
- Assign the role to the user.
- Virtual Machine User Login (for standard user access)
After assigning the appropriate role, the user was able to log in successfully.
