Looking for LDAP authentication option explained

Hi, I am a new user and I have trouble setting up LDAP authentication need help I have LDAP configured for local user only
but it shows “LDAP Online / You are not authorized to use this function”.

  • What does this mean?
  • If LDAP configuration is correct, it should authenticate users with LDAP userid and password, however, it looks like user still need to use local user’s password, not the password from LDAP server.
    Any help will be greatly appreciated.
