xrdp

Hello,
I compiled xrdp from latest cvs, no problems compiling.
But everytime I try to login (with "rdesktop localhost" or the TS- client from SuSE or from my eClients) there is an error displayed:

"Connecting to sesman ip 127.0.0.1 port 3350
sesman connect ok
sending login info to sesman
xrdp_mm_process_login_response: login failed"

Log shows only:

"granted TS access to user user
starting Xvnc session..."

Nothing else. Can anyone give a hint?

Part two:
I tried to compile an Xserver too. But the "readme" says:

"First run make World.
This is the most difficult part."

Maybe I'm a little thick - wth is "make World"? Really difficult to me.
regards
Walther
