Hello everyone,

I need some help on dns update dynamic in Samba 4 with clients linux and 

I get the following error in the log files when the machine trying to 
update the dns record:
samba_dlz: unknown key type

The computers are joined to domain succesfully and windows clients works 
without problem, but linux client (ubuntu with likewise) and osx are 
unable to make ddns updates, also adding manually the entries in dns the 
updates fails.

The samba version is 4.1.17 and bind is 9.9.5

I appreciate the help
