[Samba] xfreerdp and SPNEGO failed

[lejeczek]

hi everyone

I realise this not exactly on topic, I'm hoping an expert or 
two could confirm that following is not caused somehow by samba:

I try xfreerdp to connect to a Win10 which is a member of 
NT-style domain and it fails this way:

[14:55:33:905] [8048:8055] [ERROR][com.freerdp.core.nla] - 
SPNEGO failed with NTSTATUS: 0xC0000017
[14:55:33:905] [8048:8055] [ERROR][com.freerdp.core] - 
freerdp_set_last_error ERRCONNECT_AUTHENTICATION_FAILED 
[0x00020009]
[14:55:33:905] [8048:8055] [ERROR][com.freerdp.core.rdp] - 
rdp_recv_callback: CONNECTION_STATE_NLA - nla_recv_pdu() fail
[14:55:33:905] [8048:8055] 
[ERROR][com.freerdp.core.transport] - transport_check_fds: 
transport->ReceiveCallback() - -1

but! if that user is already logged in then xfreerdp will 
succeed.
Any thoughts?
many thanks, L.
