[Samba] Problem with /home and winbind

[John Simovic]

Can anybody tell me why when i use pam_mkhomedir to create winbind users
home directories on the fly under /home/%D/%U it disallows access to users
when logged in under windows but works fine when I point their home drives
(as an experiment) to /tmp? How can I fix it so that it works the same under
/tmp as it does under /home? Using Samba 3.0.2 security = ads.
Kind regards in advance.
