Hi guys,
I have just configured our squid proxy to use ntlm authentication.
I am failing to find correct file permission for the
/var/lib/samba/winbindd_privileged folder. Squid failed to authenticate using
winbind when the following file permissions are set 750, I get the following
error in the log.
NTLM Authentication validating user. Result: {result=BH, notes={message:
NT_STATUS_UNSUCCESSFUL NT_STATUS_UNSUCCESSFUL;
If I then change the permissions on winbindd_privileged to 757 everything works
fine. However, this is not good practice and if the server restarts then
winbind fails to start throwing the error "incorrect permissions set, 757
should be 750". Changing the permissions back allows winbind to start but squid
then stops authenticating.
My first though is that the squid user is not in the correct group, so I add
the proxy user into the winbindd_priv group using
sudo usermod -a -G winbindd_priv proxy
Check this with members winbindd_priv, indeed proxy is a member.
I then check that winbindd_priv is the assigned group for the folder, first I
Sudo chown root:winbindd_priv /var/lib/samba/winbindd_privileged/
to assigns it.
Then
Sudo ls -l root:winbindd_priv /var/lib/samba
drwxr-x--- 2 root winbindd_priv 4096 Jul 27 15:27 winbindd_privileged
It appears my proxy is not running as the "proxy" user ( I compiled squid with
--with-default-user=proxy \)
As a note I have tried adding every user to winbindd_priv, same issue occurs.
Any ideas or suggestions on how I can get ntlm working without the 777 file
permission would be great
Kind Regards
