samba - Apr 2004 - how to make umask changes permanent

I am running a Samba 3 - Atalk environment for a large number of MAC /
PC clients. How can I make umask changes affecting all users ( 002 for
instance) to stay permanent (not being reset to default values at server
restart) ?  Do I have to edit the /etc/profile file accordingly? How?

 

 

Thanks,

 

Cristian
