Hi everyone, I have installed a Samba AD DC version 4.2.11-20 in a Centos 6.7 machine and joined it in an existing domain. Everything seems working fine except I can't bind to it using LDAP simple authentication. When I try to perform a simple ldapsearch I get the following response: ldap_bind: Strong(er) authentication required (8) additional info: BindSimple: Transport encryption required.

Really Rowland? As quoted: >> I believe I need to examine TLS since when I set "ldap server require >> strong auth = allow_sasl_over_tls" or "ldap server require strong >> auth = yes" user and group queries fail. This is OBVIOUSLY using LDAP and TLS. If this was via NTLM/Kerberos, the above setting wouldn't make the slightest difference. But all that aside - the key question is: [Again, lets quit arguing i...
