[Thinlinc-technical] Guest-Session-Logon

[Peter Astrand]

Hi. It is somewhat difficult to implement a feature corresponding to the 
Ubuntu/LightDM Guest Session. The ThinLinc native client runs on top of 
SSH. A successful authentication through SSH is a requirement for anything 
else, including talking to the session manager. Thus, in order to create 
guest/temporary users, some other out-of-SSH-band solution must be used.

One such solution could be a web service (CGI script or similar) running 
on the TL server which dynamically creates guest users (or allocates from 
a pool), then call tlclient.cgi which in turn can trigger the native 
client to login. Such a web service could be developed separately, without 
access to the ThinLinc source code.

If you only need the basic functionality that the HTML5 client provides, 
another solution would be to add guest user support to the "tlwebaccess" 
service which launches the HTML5 client. In this case, SSH is not used, 
and tlwebaccess can dynamically create users. However, this requires 
changes to the proprietary tlwebaccess service.

Br,
Peter
