Issue:
Configure multiple concurrent RDP sessions to Linux VM using xrdp Service and Azure Bastion.
Solution:
You contacted Azure Support team and they suggested the following.
- Run the below to add users to the Group
- sudo usermod -aG ssl-cert User1
- sudo usermod -aG ssl-cert User2
- sudo usermod -aG ssl-cert User1
- Then execute this command individually in the shells of both users:
- echo xfce4-session >~/.xsession
- Then run the command to restart xrdp and finally, restart the VM.
Thanks,
Kapil
