Thank you. In the autofs log these lines are the most important: (Thu Oct 9 13:56:07 2014) [sssd[autofs]] [sss_dp_get_reply] (0x1000): Got reply from Data Provider - DP error code: 1 errno: 11 error message: Fast reply - offline (Thu Oct 9 13:56:07 2014) [sssd[autofs]] [lookup_automntmap_cache_updated] (0x0020): Unable to get information from Data Provider Error: 1, 11, Fast reply - offline Will try to return what we have in cache In the domain log, I see: Thu Oct 9 13:56:07 2014) [sssd[be[LDAP]]] [get_server_status] (0x1000): Status of server 'core1.whsg.info' is 'name not resolved' (Thu Oct 9 13:56:07 2014) [sssd[be[LDAP]]] [get_port_status] (0x1000): Port status of port 389 for server 'core1.whsg.info' is 'neutral' (Thu Oct 9 13:56:07 2014) [sssd[be[LDAP]]] [get_server_status] (0x1000): Status of server 'core1.whsg.info' is 'name not resolved' (Thu Oct 9 13:56:07 2014) [sssd[be[LDAP]]] [resolv_gethostbyname_files_send] (0x0100): Trying to resolve A record of 'core1.whsg.info' in files (Thu Oct 9 13:56:07 2014) [sssd[be[LDAP]]] [set_server_common_status] (0x0100): Marking server 'core1.whsg.info' as 'resolving name' (Thu Oct 9 13:56:07 2014) [sssd[be[LDAP]]] [resolv_gethostbyname_files_send] (0x0100): Trying to resolve AAAA record of 'core1.whsg.info' in files (Thu Oct 9 13:56:07 2014) [sssd[be[LDAP]]] [resolv_gethostbyname_next] (0x0200): No more address families to retry (Thu Oct 9 13:56:07 2014) [sssd[be[LDAP]]] [resolv_gethostbyname_dns_query] (0x0100): Trying to resolve A record of 'core1.whsg.info' in DNS (Thu Oct 9 13:56:07 2014) [sssd[be[LDAP]]] [request_watch_destructor] (0x0400): Deleting request watch (Thu Oct 9 13:56:07 2014) [sssd[be[LDAP]]] [resolv_gethostbyname_done] (0x0040): querying hosts database failed [5]: Input/output error (Thu Oct 9 13:56:07 2014) [sssd[be[LDAP]]] [fo_resolve_service_done] (0x0020): Failed to resolve server 'core1.whsg.info': Could not contact DNS servers (Thu Oct 9 13:56:07 2014) [sssd[be[LDAP]]] [set_server_common_status] (0x0100): Marking server 'core1.whsg.info' as 'not working' (Thu Oct 9 13:56:07 2014) [sssd[be[LDAP]]] [be_resolve_server_process] (0x0080): Couldn't resolve server (core1.whsg.info), resolver returned (5) (Thu Oct 9 13:56:07 2014) [sssd[be[LDAP]]] [be_resolve_server_process] (0x1000): Trying with the next one!
