Hello dochelp, we're receiving numerous user reports that after installing KB5028166 related updates applications on Windows clients can't authenticate anymore against Samba AD DCs. https://bugzilla.samba.org/show_bug.cgi?id=15418 It looks like the Windows update introduced changes to netlogon that are not implemented in Samba and also not documented in MS-NRPC. The logs on the Samba DC tells us the problem is a new NETLOGON_CAPABILITIES type "2": [2023/07/12 18:04:47.063445, 1, pid=11202, effective(0, 0), real(0, 0), class=rpc_parse] ../../librpc/ndr/ndr.c:490(ndr_print_function_debug) netr_LogonGetCapabilities: struct netr_LogonGetCapabilities out: struct netr_LogonGetCapabilities return_authenticator : * return_authenticator: struct netr_Authenticator cred: struct netr_Credential data : XXXXXXXXXXXXXXXX timestamp : (time_t)0 capabilities : * capabilities : union netr_Capabilities(case 2) UNKNOWN LEVEL 2 result : NT_STATUS_NOT_SUPPORTED MS-NRPC only documents type 1: <https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-nrpc/f03cad67-077f-4042-80b0-cdc38dca9968> Please read my description with a grain of salt, I'm not the netlogon expert on our team, just wanted to set the ball rolling... :) Thanks! -slow -- Ralph Boehme, Samba Team https://samba.org/ SerNet Samba Team Lead https://sernet.de/en/ _______________________________________________ cifs-protocol mailing list cifs-protocol@lists.samba.org https://lists.samba.org/mailman/listinfo/cifs-protocol
