[Samba] Issue with FAST implementation ? Disabling really disable ?

[Olivier BILHAUT]

Hi list, 

Juste migrating from samba 4.14 to samba 4.16.3. Most works
fine and thanks again for this great work. 

However I have an issue
with a smbclient run locally which seems to fail due to a FAST issue.
The command is run from the DC itself : 

-- 

$>
/USR/LOCAL/SAMBA/BIN/SMBCLIENT \\\\DOMAIN.TLD\\NETLOGON -UDOMAIN/ACCOUNT
-PPASS 

gse_get_client_auth_token: gss_init_sec_context failed with [
Miscellaneous failure (see text): FAST fast response is missing FX-FAST
(cifs/DOMAIN.TLD at LOCAL)](2529639059)
gensec_spnego_client_negTokenInit_step:
gse_krb5: creating NEG_TOKEN_INIT for cifs/domain.tld failed
(next[(null)]): NT_STATUS_LOGON_FAILURE
session setup failed:
NT_STATUS_LOGON_FAILURE 

-- 

I have tried to disable FAST with " kdc
enable fast = no" (and restart) as I have seen in release note, but now
way. 

Any advice ? 

Have a nice day !
