[Samba] smb.conf template homedir

[Karen R McArthur]

For local login to our samba server, we are using posix information 
stored in an openldap directory. - I can log in via shell with no problems.
We are authenticating samba against AD2003.  I can attach to the samba 
server from both windows and macintosh - just not access my home directory.
Currently, "template homedir = /home/%U" - which results in a path of 
/home/<username>
I would like to use the homeDirectory field found in openldap - which is 
different for different classes of users.
i.e.:
     /usr/guests/guest_name
    /usr/netapp/student/student_name
    /usr/netapp/faculty/faculty_name
    /usr/netapp/staff/staff_name

I have tried templete homedir = %$(env HOME), but it does not work:
Aug 24 14:04:46 vmnode10 smbd[15826]: [2006/08/24 14:04:46, 0] 
lib/substitute.c:expand_env_var(190)
Aug 24 14:04:46 vmnode10 smbd[15826]:   expand_env_var: Environment 
variable [HOME] not set

I assume I just can't figure out the correct syntax for the "template 
homedir".  Could someone point me in the right direction?
Thanks,
