[FreeNX-kNX] Authentication Failed! Nomachine Kb won't help!

Tue Aug 8 13:17:04 UTC 2006

Hello 

I have installed nxclient, nxnode and nxserver on my linux box running 
mandrake 10 but I couldn get any user o to logon. 

I have installed and re-installed the server so many times that I have 
already forgot when the first time was. 

This is the error msg I got when 

rpm -ivh nxserver-2.0.0-74.i386.rpm

I read articles #AR10B00046, #AR11B00076 and #AR04D00382 (useless) but 
couldn figure out what to do. 

Any suggestions? 

Many thanks

Ps. my ssh_config (ssh works just fine)
