17 chars longInvalid configuration. Exiting ....Failed to join domain: The

This is a limitation from windows, you cannot have a netbios name that 
is longer than 15 characters, so if you must have the fact that it is in 
AD and is a client running centos as the short hostname, then try 
'adclientcentos' instead

Complementing my problem is with linux stations.

"... so if you must have the fact that it is in AD and *is a client running

also, can't you change the name to something less than 15 chars ?

Thanks for listening. I appreciate your understanding. I need to know if the
samba supports customers with but 15 characters. In exeplo using was
illustrative. I have clients with but of 15 characters. Ex: Apocalypse-master

You *cannot* have a netbios name with more than 15 characters.

This limitation comes from windows.

You don't have to rename your machine, you can set a shorter name in 
smb.conf:

[global]
netbios name = shortname

It's too bad samba doesn't auto-shorten hostnames like Windows does, 
though being able to name them yourself gives you more control on how the 
names get shortened.  One downside to this is that since Kerberos is DNS 
based, if you use Kerbros credentials for authentication between machines, 
you will need to put a CNAME in DNS for the short hostname pointing to the 
real hostname.

I'm curious if NetBIOS names are actually required by AD, or are just 
there by default for compatibility with older versions of Windows.  If the 
later, it would be nice if it was possible to disable them completely in 
Samba.

Good afternoon even disabling the netbios "disable = yes netbios" he
continues using the netbios.
