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 TLS_CACERT /etc/ssl/certs/ca-certificates.crt TLS_REQCERT allow 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 https://www.samba.org/samba/history/ Look a the smb.conf changes.
