Hello Jim, 

I tested with Selinux on or off, no difference. 
Thanks for helping me ou though. 
I seems Centos7 is eluding a lot of ltsp-people these days. 

Greetings, Johan

Disable selinux with setenforce 0 and retry. Or you can go digging in the audit log for clues.

Hello, 

it could be this is related to Lightdm, the server has mate-desktop installed. I'm also seeing this EM:

Hello Barry, Hello All, 

so I'm also experimenting on Centos7. 

I followed the procedure described by Barry below. 

The thinclient boots fine, but users or root can't logon. 
The EM I'm seeing is: 
Apr 14 11:46:02 localhost sshd[5003]: Connection closed by 192.168.63.130 [preauth] 

I tried the usual, ltsp-update-sshkeys, Selinux, ... 

Can anyone help me with this? 

Many thanks. 

Johan
