Hello all. I have a Samba 3.5.4 server that we're attempting to join to an existing Windows 2008 ADS. Doing "net ads join" seems to go ok, and a follow up "net -P ads testjoin" says we're OK. However... at this point, doing "wbinfo -u" or "wbinfo -g" returns no data (the programs exit with erro code 0, and no output). Attempting to log into a share on the samba machine from a Windows XP client fails (username/password are not accepted). The exact same configuration, using samba 3.3.0, works perfectly. Running winbindd on the console (winbindd -d 10 -F -s /var/etc/smb.conf -S -i) shows me the following when I try to run "wbinfo -u": child daemon request 63 child_process_request: request fn NDRCMD winbindd_dual_ndrcmd: Running command WBINT_DSGETDCNAME (no domain) wbint_DsGetDcName: struct wbint_DsGetDcName in: struct wbint_DsGetDcName domain_name : * domain_name : 'DOMAIN.ARRIAD.COM' domain_guid : NULL site_name : * site_name : '' flags : 0x00000000 (0) dsgetdcname: domain_name: DOMAIN.ARRIAD.COM, domain_guid: (null), site_name: , flags: 0x00000000 debug_dsdcinfo_flags: 0x00000000 Returning valid cache entry: key = AD_SITENAME/DOMAIN/DOMAIN.ARRIAD.COM, value = Default-First-Site-Name, timeout = Mon Jan 18 22:14:07 2038 sitename_fetch: Returning sitename for DOMAIN.ARRIAD.COM: "Default-First-Site-Name" Returning valid cache entry: key = DSGETDCNAME/DOMAIN/DOMAIN.ARRIAD.COM, value = , timeout = Mon Jul 19 16:18:54 2010 info: struct netr_DsRGetDCNameInfo dc_unc : * dc_unc : 'ads_machine.DOMAIN.arriad.com' dc_address : * dc_address : '\\10.0.8.36' dc_address_type : DS_ADDRESS_TYPE_INET (1) domain_guid : c8d2ab8f-6a0f-4ddf-9be8-dfb32c4af4c2 domain_name : * domain_name : 'DOMAIN.arriad.com' forest_name : * forest_name : 'DOMAIN.arriad.com' dc_flags : 0xe00013fd (3758101501) 1: DS_SERVER_PDC 1: DS_SERVER_GC 1: DS_SERVER_LDAP 1: DS_SERVER_DS 1: DS_SERVER_KDC 1: DS_SERVER_TIMESERV 1: DS_SERVER_CLOSEST 1: DS_SERVER_WRITABLE 1: DS_SERVER_GOOD_TIMESERV 0: DS_SERVER_NDNC 0: DS_SERVER_SELECT_SECRET_DOMAIN_6 1: DS_SERVER_FULL_SECRET_DOMAIN_6 1: DS_DNS_CONTROLLER 1: DS_DNS_DOMAIN 1: DS_DNS_FOREST dc_site_name : * dc_site_name : 'Default-First-Site-Name' client_site_name : * client_site_name : 'Default-First-Site-Name' wbint_DsGetDcName: struct wbint_DsGetDcName out: struct wbint_DsGetDcName dc_info : * dc_info : * dc_info: struct netr_DsRGetDCNameInfo dc_unc : * dc_unc : 'ads_machine.DOMAIN.arriad.com' dc_address : * dc_address : '\\10.0.8.36' dc_address_type : DS_ADDRESS_TYPE_INET (1) domain_guid : c8d2ab8f-6a0f-4ddf-9be8-dfb32c4af4c2 domain_name : * domain_name : 'DOMAIN.arriad.com' forest_name : * forest_name : 'DOMAIN.arriad.com' dc_flags : 0xe00013fd (3758101501) 1: DS_SERVER_PDC 1: DS_SERVER_GC 1: DS_SERVER_LDAP 1: DS_SERVER_DS 1: DS_SERVER_KDC 1: DS_SERVER_TIMESERV 1: DS_SERVER_CLOSEST 1: DS_SERVER_WRITABLE 1: DS_SERVER_GOOD_TIMESERV 0: DS_SERVER_NDNC 0: DS_SERVER_SELECT_SECRET_DOMAIN_6 1: DS_SERVER_FULL_SECRET_DOMAIN_6 1: DS_DNS_CONTROLLER 1: DS_DNS_DOMAIN 1: DS_DNS_FOREST dc_site_name : * dc_site_name : 'Default-First-Site-Name' client_site_name : * client_site_name : 'Default-First-Site-Name' result : NT_STATUS_OK Finished processing child request 63 Writing 3912 bytes to parent dsgetdcname failed: NT_STATUS_ACCESS_DENIED wb_request_done[21194:DSGETDCNAME]: NT_STATUS_ACCESS_DENIED winbind_client_response_written[21194:DSGETDCNAME]: deliverd response to client process_request: Handling async request 21194:DSGETDCNAME [21194]: dsgetdcname for DOMAIN.ARRIAD.COM dsgetdcname failed: NT_STATUS_PIPE_BROKEN wb_request_done[21194:DSGETDCNAME]: NT_STATUS_PIPE_BROKEN winbind_client_response_written[21194:DSGETDCNAME]: deliverd response to client process_request: Handling async request 21194:DSGETDCNAME [21194]: dsgetdcname for DOMAIN.ARRIAD.COM dsgetdcname failed: NT_STATUS_PIPE_BROKEN wb_request_done[21194:DSGETDCNAME]: NT_STATUS_PIPE_BROKEN winbind_client_response_written[21194:DSGETDCNAME]: deliverd response to client process_request: Handling async request 21194:DSGETDCNAME [21194]: dsgetdcname for DOMAIN.ARRIAD.COM dsgetdcname failed: NT_STATUS_PIPE_BROKEN wb_request_done[21194:DSGETDCNAME]: NT_STATUS_PIPE_BROKEN winbind_client_response_written[21194:DSGETDCNAME]: deliverd response to client closing socket 24, client exited accepted socket 24 So we're apparently able to contact the ADS, send a request, but the request is being denied. What has changed between 3.3.0 and 3.5.4 that would cause us to start getting an ACCESS_DENIED error in response to such a basic rpc request? -Samrobb
