The following happens with the SELinux packages from MicroOS 5.1 on SLES15SP3.
User "testuser" has been assigned SELinux user user_u and attempts to log in
via ssh, using key authentication

TEST: verify that the SSH key we generated can be used for authentication
== Authorizing ssh key id_rsa ==
client: echo $HOME; user=testuser
client: downloading /home/testuser/.ssh/id_rsa.pub
server: mkdir -m 0755 -p ~/.ssh; user=testuser
server: uploading data to /home/testuser/.ssh/authorized_keys
client: ssh -oStrictHostKeyChecking=no server true; user=testuser
