You claimed it was inconsistent because syncrepl refers to ldap.conf for network timeout settings while
back-ldap makes no reference to ldap.conf.

Clearly there is no requirement for syncrepl and back-ldap to behave identically here.

For the TLS settings, as already noted, libldap always reads ldap.conf unless you set the NOINIT
env var. All of the slapd TLS settings are set in a TLS context that is retrieved from an LDAP*
handle created specifically for this purpose. Naturally this handle inherits whatever defaults
libldap picks up. Even so, you are expected to completely configure TLS settings in slapd's
configuration, and not rely on any other defaults.

Feel free to add a note to slapd.conf(5) / slapd-config(5) about TLS defaults.
