Re: [cobalt-security] SMB Group Shares Vulnerable to Web Access

Thanks Jeff.

This works for me, I also replaced the default index.html pages with one 
which does a redirection to /home/groups/home/ in the situations where I 
don't want an "index".  The file permissions also needed to be altered so 
users can't "accidentally" delete index.html.

This does raise an issue ... shouldn't this all be done the other way 
around?  Shouldn't the default be that group authentication is required 
for the group root (i.e. there should be be a "public" subdirectory 
instead of a "private" subdirectory)?

I believe these access restrictions are inconsistent ... the default for 
an SMB group share is group authentication ... shouldn't web access be 
the same directory also require group authentication?

I guess the situation is exactly the same in users home directories.

Cheers,  Malcolm
