[Samba] Problem with Samba 4.0.4 to 4.1.19 update

[Gabriel Franca]

good day Ali Bendriss,

I followed exactly this tutorial to update the samba.

Thank you, everyone I'll be honest as I have full knowledge about the Samba 4 will redo the structure thus have more work more on the other hand I'm sure I will not make a mistake that can generate me more trouble.

Regards,

Gabriel Franca
