Administrator account password not recognised (Unable to bind LDAP server)

Still digging:

I’m confuse with this one.
The standard connexion to LDAP works and not the TLS one:
Is it something expected? Since .cert and .key are specified within the slapd conf but that we are using port 389 (instead of the default 363 for TLS).

But a connection test result in a “Can’t contact LDAP Server (-1)”
