[Samba] Samba, Time Machine, and ADS

[L.P.H. van Belle]

TimeMachine is NOT enabled in the official debian packages. 

If you want time machine, report it at debian as bug/request if you want this enabled, and untill then, 
You can use my packages, where timemachine is enabled. 

Or rebuild the the debian packages your self and enable it, that part only is very easy. 

+ what Rowland told you. ;-) 

Greetz, 

Louis
