Samba shares suddenly requiring password?

uhcafigdc · 06-17-2011, 10:08 AM

The setup is that users can access the samba shares and read/write without entering a username/password.

Windows XP users today are suddenly prompted for username/password, and can't connect. No combination of user/pass seems to work.

Nothing in the smb.conf has changed recently. The shared folder still exists on the server and has the same permissions as before.

Here is the smb.conf:

Code:

[global]

	workgroup = workgroup
	netbios name = F1
	server string = J

	level2 oplocks = no
	oplocks = no

	hosts allow = 192.168.1. 127.
	load printers = no
	guest account = nobody
	log file = /var/log/samba/%m.log
	max log size = 50
	
	security = share
	encrypt passwords = false

	socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
	
	
[j]
        path = /home/j
	browseable = yes
        writeable = yes
	guest ok = yes
	public = yes

Here are some recent entries in /var/log/smbd.log:

Any ideas?

Fixed! A recent windows update kb2536276 breaks samba when "encrypt passwords = no" is set.

Solution is to set "encrypt passwords = yes"
