I wrote this script which now works perfectly on systems without SElinux installed.
echo Enter server IP:
read server
scp /home/Zenoss/.ssh/authorized_keys random@$server:/home/random
sshpass -p randompassword ssh -t random@$server sudo -i 'useradd zenoss; sudo mkdir /home/zenoss/.ssh; sudo mv /home/random/authorized_keys /home/zenoss/.ssh/;
sudo chmod 700 /home/zenoss/.ssh;
sudo chmod 600 /home/zenoss/.ssh/authorized_keys;
sudo chown -R zenoss /home/zenoss/.ssh;
sudo chgrp -R zenoss /home/zenoss/.ssh;
exit'
So on servers without SElinux the script works and then Zenoss can log in to the remote server via SSH and start to monitor. However on systems with SELinux enabled, the script works, but Zenoss cannot SSH onto the remote server, the debug information shows that its not seeing the authorized_keys file that was successfully set up.

Does anyone know what causes this and how I can work around it, disabling SELinux isnt an option.

Most likely the context of
.ssh
and.ssh/authorized_keys
file is wrong. Do asudo restorecon -R -v /home/zenoss/.ssh
and try again.
