samba - May 2002 - OT: OS2 & Samba: "Your home directory could not be set up"

Hi people,

maybe offtopic.
When logging in from OS2/Warp-4 the message
"Your home directory could not be set up" 
apears on the OS2-WPS.

Any hint how to avoid this message ?

My Config : 

Samba 2.2.4 on Linux (Kernel 2.4.18).
Client ist OS2-Warp 4 (Merlin)

greets Harry
