NethServer Version: NethServer release 7.4.1708
I’m trying to get a Synology NAS box to connect to an LDAP server hosted on a NethServer.
I’ve installed the NethServer box as an AD account provider.
I’m aware of the different IP and FQDN needed at my NethServer for AD. Fine. That’s my LDAP client target. I’m also aware of the ldapservice account used as a BIND DN, which is what i’m using to connect.
I’m using a self signed cert on the NethServer and the box is not internet reachable so let’s encrypt isn’t an option.
A tcpdump using no encryption between the Synology box and the NethServer show’s: “strongAuthRequired” “Transport encryption required” “Operation unavailable without authentication” “LDAPMessage unbindRequest” LDAP errors.
If SSL/TLS or STARTTLS are used from the LDAP client the results are the same I can’t bind to the NethServer.
Using LdapAdmin.exe from a Windows box in order to browse the NethServer LDAP structure, using the same credentials “email@example.com” along with SSL/TLS (giving a certificate warning - self signed)… works just fine.
Any idea at troubleshooting this would be welcome. Starting with the LDAP logs on NethServer.
