Invalid tls= description in example.ldap. Missing ssl= description

## tls (default yes): if set to 'yes' then TLS connection will be
## attempted to your ldaphost by using the URI base ldaps: otherwise ldap: will be used

This is valid for ssl=, but not for tls=. Miss of ssl= description leads to unpredicted errors when using self-signed certificates, as tls=no, but it still using ldaps:// =)
