Bug ID: 390798 Summary: Akonadi EWS failed to authenticate with Exchange Server Product: Akonadi Version: 5.7.2 Platform: Neon Packages OS: Linux Status: UNCONFIRMED Severity: major Priority: NOR Component: EWS Resource Assignee: kdepim-b...@kde.org Reporter: olivier.dug...@orange.com CC: kri...@op.pl Target Milestone: --- Once configured Akonadi EWS plugin, clikc on "Test Connection work", but click on "OK" failed and plugin remains not connected. Once activate kio_http debug, it seems that the NTLM handshake is correctly executed when testing the connection. Akonadi EWS try without any auth, got a 401, then try with simple NTLM v1, got 401 again, and finally try with NTLMv2 and got a 200 OK. When clicking on "OK", Akonadi EWS just try NTLMv1 and newer try NTLMv2. It seems that this bugs is related to old NTLM problem in kio_http patched by the author of akonadi_ews plugin. Note that same credential with Exchange or Thunderbird work fine and that using a kerberos ticket allows authentication. -- You are receiving this mail because: You are watching all bug changes.
