restricted shares

[squeegy+netatalk]

I want to have shared folders that some users have access to and othrs
do not.  Is this handled through setting setting the proper UNIX
permissions on the shared directories or is this handled through a
configuration file.  

also can I restrict following symbolic links in netatalk?  Should I?  
What file is the proper file to put global shares in,
AppleVolumes.default or AppleVolumes.system?

Thank you
