hello, I try to query an active directory from asterisk. I do not see how to do it because I just started in asterisk. In extensions.conf switch => Realtime/default at realtime_ext In res_ldap.conf [general] host = ip_active directory protocol = 3 port = 389 dn = ou=voip,dc=test,dc=com pass = administrator_pass_activedirectory user = ou=Users,cn=Administrateur,dc=test,dc=com URL = ldap://ip_activedirectory:389/ou=voip,dc=test,dc=com [extensions] attribute = name =>uid attribute = accountcode => uid attribute = callerid => cn In extconfig.conf [settings] realtime_ext => ldap,dc=test,dc=com,extensions sipusers => ldap,dc=mydomain,dc=com,sipusers sippeers => ldap,dc=mydomain,dc=com,sippeers when i try to register save a user I get the following message : Warning[1952]: config.c:2025 find_engine:Realtime mapping for 'sippers' found to engine 'ldap' but the engine is not available Notice[1952] : chan_sip.c:21500 handle_request_register:Registration from '"user"<sip:user at 192.168.xxx.xxx>' failed for 'ip_activedirectory' no matching peer found. I see no potential source or error in the configuration if you have a idea i'm willing Thank You Best Regards Mickael
