nis/nfs network authentication with kde interface problem

I use in a small lab network NIS authentication method with home directories exported by NFS from a file server. All other desktop enviroments (gnome, wmaker, icewm, etc.), except kde, work fine. When I try logging and using kde enviroment, the system freezes. Do you have any ideas why?
Thanks!

Quoted

Do you have any ideas why?

No, because you didn't provide that much information. Does the file ~/.xsession-errors say something useful? And at what step does it freeze? Immediately after login or after the environment has loaded?

RE: nis/nfs network authentication with kde interface problem

Sorry for the vague description of the problem.
Exactly:
-I have an application server (because some applications are installed only on that server), a file server and some PCs.
-The application server exports by NIS (ypserv) usernames and passwords in the network and the file server shares by NFS a directory with users home files.
-On every station in the network I have a NIS client (ypbind) and I mount the directory shared by the file server in the local /home directory. Also, on every station I use X11 with gdm for login.
-In the gdm login window, if I choose whatever display manager (gnome, wmaker, etc.), excepting kde, everything works well.
-In the gdm login window, if I choose KDE, after login ksplash runs a quite long time and after that I have nothing on the screen, except the background image, and I can do nothing with the computer.
-The .xsession-errors files is:


/etc/X11/gdm/PreSession/Default: Registering your session with wtmp and utmp
/etc/X11/gdm/PreSession/Default: running: /usr/X11R6/bin/sessreg -a -w /var/log/wtmp -u /var/run/utmp -x "/var/lib/gdm/:0.Xservers" -h "" -l ":0" "student"

RE: nis/nfs network authentication with kde interface problem

I observed the problem is between KDE and NFS and, finally, I managed to solve it removing from the script /usr/bin/startkde the lines

KDE_FULL_SESSION=true
export KDE_FULL_SESSION

I am no expert in KDE, can anyone to explain me why was this the solution to my problem?
I know that, if KDE_FULL_SESSION=true, some supplementary programs (or scripts) are invoqued at the start of KDE. I suppose the problem is between those programs (scripts) and KDE.
