[Samba] Missing Macros

[Charles Hamel]

I read the smb.conf manual but I can't find what I want, is there any way to
get the secondary group of a user using a macro ? I want to use a perl script
to create logon script depending on the groups of the users using the root
preexec parameter in smb.conf, but they the primary group is always "Domain
users" so my script cant make the difference.

Is there any way to fix this ? Thank you
