Hi Amos and others.
Its not a "samba" thing or a squid thing.
Maybe in the end yes, but this is a configuration thing.
For you guys to know, samba AD DC setup this parameter as default :
ldap server require strong auth = yes
Which obligates the use of TLS.
Next, users dont configure /etc/ldap/ldap.conf when they use TLS.
Squid and samba may need the CA root if you use TLS.
Which should to in ldap.conf
Samba sets these days:
ntlm auth = no
Laman auth = no
Which disables NTLMv1 and last, users dont know kerberos and the need of A/PTR records.
For others, i've posted a example auth setup and smb.conf setup for squid on Debian Jessie.
Tested as of squid 3.4.8 upto 3.5.24. ( with and without ssl bumping )
Google for : Problems with Samba 4.6.3 Authentication
Post date 23-may 2017
When upgrading samba/winbind as of 4.2 upto 4.5 or 4.6.
You MUST read the change logs at least for every samba 4.X.0 version. \
At least 4.2.0 4.3.0 4.4.0 4.5.0 and 4.6.0
Look a the smb.conf changes.
Like this one for 4.5 :
Parameter Name Description Default
-------------- ----------- -------
kccsrv:samba_kcc Changed default yes
ntlm auth Changed default no
only user Removed
password hash gpg key ids New
shadow:delimiter New _GMT
smb2 leases Changed default yes
