[Samba] Supplementary Group Changes

[Jon Delheimer]

Is there a signal that can be sent to the smbd process, or some other 
method to tell smbd to reload the user's supplementary unix groups? We 
do not use Windows Domains and all access to files is controlled using 
Linux ACLs and supplementary groups defined using a web interface. 
Currently, when a new posix group is created and given access to a 
folder, the members of the group do not gain access unless their 
associated smbd process is killed first. Although this works, it's a bit 
disruptive.
