res_config_ldap.c:1665 parse_config: No directory URL or hos

Hi to all!
I want to connect a Sipml5 application to my asterisk 11.11.0 (installed in a centos 6.5), but I have this error in asterisk :

= Parsing '/etc/asterisk/res_curl.conf': Found -- Reloading module 'res_config_ldap.so' (LDAP realtime interface) == Parsing '/etc/asterisk/res_ldap.conf': Found [Aug 15 00:26:40] NOTICE[15942]: res_config_ldap.c:1639 parse_config: No directory user found, anonymous binding as default. [Aug 15 00:26:40] ERROR[15942]: res_config_ldap.c:1665 parse_config: No directory URL or host found. [Aug 15 00:26:40] NOTICE[15942]: res_config_ldap.c:1599 reload: Cannot reload LDAP RealTime driver.

I think that I need to have this module to connect the sipml5 to asterisk? How can I solve this problem?
Thanks a lot!

That message has nothing to do with the websocket layer. if you arenĀ“t using LDAP authentication then you can ignore it.
