Description of problem: Recently Windows Server 2019 has started producing non-complaint PPP success packets which have a space missing before the M= in the packet. The following recent upstream patch handles the missing-space non-compliant success packets: https://github.com/paulusmack/ppp/commit/3cd95baf3f1de1d5a9bc89be0f4c3215ceb5aefe.patch
macOS already handles the missing space before M=, extract from : https://opensource.apple.com/source/ppp/ppp-862.120.2/Helpers/pppd/chap_ms.c.auto.html //we'll allow the missing-space case from the server, even though //it's non-conforming to spec! dbglog("Rcvd non-conforming MSCHAPv2 Success packet, len=%d", len); if(len >= 2 && !strncmp((char*)msg, "M=", 2)) msg += 2; else { error("MS-CHAPv2 Success packet is badly formed."); return 0; }
Thanks for info, I don't have problem to use the patch downstream till new release will happen.
