- add support in rlm_ldap for reading clients from ldap

Browse Source 
- fix TLS parameter controling if a cert which fails to validate will be
    accepted (i.e. self-signed), rlm_ldap config parameter=tls_require_cert
    ldap LDAP_OPT_X_TLS_REQUIRE_CERT parameter was being passed to
    ldap_set_option() when it should have been ldap_int_tls_config()
