I am trying to connect to a samba share with Windows 10 Pro (Version 1511, Build 10586.589) using the command net use L: \\myserver\myshare /u:myuser mypassword
. I get the error:
System error 86 - The specified network password is not correct.
I get the same result when using the Map network drive dialog. Other clients (Android, Linux) can connect just fine with the same user/password.
I have tried adjusting the following security policies via secpol.msc:
- Microsoft network client: Send unencrypted password to third-party SMB servers (enabled and disabled)
- Netword security: LAN Manager authentication level (Send LM & NTLM responses, Send LM & NTLM - use NTLMv2 session security if negotiated
- Network security: Minimum session security for NTLM SSP based clients/servers (128-bit encryption and none)
I am running samba 4.5.0-2 on Arch Linux (4.7.4-1). Server-side, I have reset the user password, removed and re-added the user to the smbpasswd backend, and started and restarted the smbservice.
My smbconf is basically the default:
[global]
workgroup = MYGROUP
server string = Samba Server
log file = /var/log/samba/%m.log
max log size = 50
security = user
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
unix password sync = Yes
passwd program = /usr/bin/passwd %u
passwd chat = *New*UNIX*password* %n\n *ReType*new*UNIX*password* %n\n *passwd:*all*authentication*tokens*updated*successfully*
dns proxy = no
[my share]
comment = my share
browseable = yes
writable = yes
guest ok = no
path = /pathto/myshare
public = no
valid users = myuser
create mask = 770
I don't see anything out of the ordinary in testparm, and I have confirmed via pdbedit that my user is definitely registered with the backend.
It has worked fine before today and I do not know why it suddenly stopped working. Any advice is greatly appreciated.
