Also, your authorizers.xml is not correct — you haven’t configured (or even uncommented) the LDAP user group provider, so the specified user group provider is the file users.xml, and you haven’t configured any initial admins, so no users will be allowed to log in. Did you follow the steps in the NiFi Admin Guide [3][4] for configuring this? Authentication and authorization are decoupled in NiFi, and while you can use LDAP for both, you’ll have to configure it for each.
Also, your login-identity-providers.xml uses START_TLS as the authentication strategy but does not specify any properties for the keystore or truststore, which will be required.
