I have installed and configured Samba as PDC with Heimdal kerberos and 
openLDAP as backend for both on debian lenny. But i stuck on groups.
I have created a file in my home directory mapped to my documents. I can 
change rwx permission on linux and windows and it works perfectly. but this 
file has as a group my default group. this file should be read by users from 
accounting and managers group too.  but when i want to add additional group 
in security tab i get access denied. What should I do to be able to add 
additional groups.
