[Samba] re reading config

[Miguel Medalha]

You can force it  without restarting with the following commands:

For smbd
smbcontrol smbd reload-config

For nmbd:
smbcontrol nmbd reload-config

For winbind:
smbcontrol winbindd reload-config

The process number can also be used instead of the daemon's name.

For samba version > 3.3 you can force all 3 daemon's to reload 
configuration with the following command:

smbcontrol all reload-config
