[Samba] Failed auth attempt i don't understand.

Hi all,

when i try to authenticate against my AD (rdesktop authentication) i got 
a wrong password/logname message despite my logname and password
being exact , in the log i have the following .

Nothing wrong for me.

the only strange thing being the : stream_terminate_connection: 
Terminating connection - 'kdc_tcp_call_loop: 
tstream_read_pdu_blob_recv() - NT_STATUS_CONNECTION_DISCONNECTED' line 
in perticular the second one because just after things seems to continue 
with the :

Kerberos: TGS-REQ Administrator at LOCAL.MYDOMAIN from 
ipv4:192.168.1.23:62418 for host/vr083023.LOCAL.MYDOMAIN at LOCAL.MYDOMAIN 
[canonicalize, renewable, forwardable]

line.

Can anyone with more knowledge than me have an eye on the log and tell 
me if he see anything wrong ?

and by the way ,under debian bullseye i can't seems to find anyway to 
get the full log of samba.
despite this line :
log level = 6;
in my conf i can' seems to obtain the same level of log i get by doing :

samba -i -d 6  --debug-stderr

if anyone know why, and how i can get my log to this level without 
launching my samba in interractive mode , i'm very interested.

best regards

Is this on a DC or a Unix domain member ?

Why are you using Administrator on Unix ?

Might help if we see your smb.conf

this is a remote desktop attempt on a computer who is in the domain 
managed by the DC from which i get the log
> Why are you using Administrator on Unix ?
This is the default administrator account in samba4 but the behavior is 
the same with any account.

[Samba] Failed auth attempt i don't understand.

Ive seen something simular here. 

Does this happen if you try to connect to a PC where you already are logged in. 
If yes, logout, test again. 
If no, reboot the pc and test again. 

What is the exact message you see. 
(optinal PM me the print screen) 
I do/did get some 0x... Message when trying to login on first attempt.
The second always worked for me. 

And lookup the windows events. 
Or are we talking here about RDP on linux workstations?  ;-) 


Greetz,
