[Samba] When to restart samba

[Andrew Masterson]

Thanks for the info - I've gotten conflicting info from SWAT, Webmin and the man pages, so I thought I would ask.  It appears that there isn't a hard rule for when to restart vs. wait for autoload so I'll have to play with it a bit to figure out when and what.

Yes, winbindd and smbd should be restarted after changing the global stanza of
smb.conf.  In reality, this is only necessary when global parameters have
been changed that may impact Samba's behavior.  For example, changing
the "log level" parameter does not require restarting of any Samba daemon. 
Check the man page for smb.conf to determine if a restart is perhaps
necessary.

That depends on the OS.  On some older systems this can take 20 sec or so, on
all modern systems the change is almost immediately effective.
