[Samba] samba4 domain member

[marco pirola]

Hi everyone. I have 2 vps: one configured as pdc (witch ip address 
192.168.1.6) fully functional. On the second vps I would like to create 
a domain member and have it join on the pdc. I read the wiki 
https://wiki.samba.org/index.php/Setting_up_Samba_as_a_Domain_Member but 
I can not understand the guide. For example, pearl of krb client but 
does not say (use debian streatch) what I have to install to get it. 
Could someone pass me a link that explains how to create a member of 
domain? Thank you for your cooperation
