Hi all,

I am looking to do some inter user communication with DCOP, as is documented 
on developer.kde.org.  I'm doing the root backend/user priveledges front end 
thing, on KDE 3 (HEAD from cvs)

The docs state:

ICEAUTHORITY=~user/.ICEauthority kdesu root -c kcmroot -dcopserver `cat 
~user/.DCOPserver`

is the way to do this.  However, this no longer works - firstly, as you'll 
know, the .DCOPserver file is stored as .DCOPserver_systemname_display ID.  
This is not really a problem, as I can use the DCOPClient::dcopServerFile to 
get this.  Also, 'cat ~/.DCOPserver' produces two lines of output, the first 
being the path to the dcop server. This though, can also be got round 

However, even with all this changed, the command still does not work:

ICEAUTHORITY=/home/mark/.ICEauthority kdesu root -c kate --dcopserver 
local/mark-debian:/tmp/.ICE-unix/dcop563-1008786730

is what I'm running just for testing purposes.  Kate runs as root, but then a 
error message comes up 'There was an error setting up inter-process 
communications for KDE.  The message returned by the system was: 
Authentication Rejected, reason: None of the authentication protocols 
specified and supported and host-based authentication failed'.

This is half a bug report and half a plea for help!

Many Thanks

Mark
