Need some help with various problems on a Linux server

I have a CentOS 7 server running in a VM with some issues that need to be solved. It is running a graphical engineering application. To connect to the machine the users are using the Windows build-in Remote Desktop Client. To make this possible xrdp (using vnc in the background) has been installed on the server.

These are the open issues in order of importance/urgency.

- xrdp has a problem reconnecting to existing sessions. The way it should work is when a user has an existing session open xrdp/vnc always reconnects to the existing session. But now when they re-connect using a different client resolution a new gnome session is started. There are articles about it. I followed them but it doesnt work. So I do something wrong.

- xrdp becomes slow when there is load on the server (when calculation jobs are running). So we have to see if we can increase the prio of the xrdp and vnc processes. So the server doesnt become sluggish when there is load.

- The machine is joined in a FreeIPA domain. But logging on to the server using freeIPA doesnt work anymore. Id like to get some tips on basic troubleshooting steps when connecting doesnt work.

- Some basis explanation on the things I can do with FreeIPA in terms of privilege management. For example allow users to run certain commands as sudo.

- I have problems in really understanding on how to assign certain users rights to run certain commands using sudo. So we need to go over some examples to make sure I understand it.

- going over the options to allow only a certain user access to the internet and block it for other users.

What is important for this?
- Being able to work on this during business hours is a big plus
- I (preferably) need someone with demonstrated good experience with xrdp and FreeIPA, knowledge of CentOS and also GNOME desktop issues. Please be honest about your level of experience in these areas.

I cannot give you ssh access remotely on the production machine. It needs to be done over a remote support session. What I can do is setup a test CentOS setup similar to the one we have and give you remote access there. You can also install one yourself.

Im looking for someone for a longer term cooperation on which I can rely when having issues with the server. Again preferably during working hours.

My estimation would be that this job will take 4 to 6 hours of work.
