Dear Maintainer,

I have not been able to connect to my headless server using Remmina since some update
during the last few months. I am not exactly sure when the regression started.

By searching the net I found a solution to the problem: The user xrdp must be a member
of the group ssl-cert, which apparently not was the case on at least two Debian systems and
a Raspberry Pi running Raspberry Pi OS (it's Debian).

This is what I did to fix the problem:

 sudo adduser xrdp ssl-cert
 sudo systemctl restart xrdp

Or perhaps better, reboot, which I had to do with the headless server.

The error message that signals this is the problem, is the following, it appears in
/var/log/xrdp.log, and also in systemctl status xrdp:

 [ERROR] MAC checksum error for non-FIPS PDU

Thank you for your work!
