Members

authenticationType

MI_AUTH_TYPE_DEFAULT (MI_T("Default"))

Transport picks the default specific to it. For example, Windows Remote Management (winrm) uses Kerberos and NegotiateWithoutCredentials as default.

MI_AUTH_TYPE_NONE (MI_T("None"))

Do not authenticate, most servers require some kind of authentication.

MI_AUTH_TYPE_DIGEST (MI_T("Digest"))

Uses Digest authentication. Requires username/password. Some servers and transports do not support this type of authentication.

MI_AUTH_TYPE_NEGO_WITH_CREDS (MI_T("NegoWithCreds"))

Uses SPNEGO authentication. Requires username/password.

MI_AUTH_TYPE_NEGO_NO_CREDS (MI_T("NegoNoCreds"))

Uses SPNEGO authentication with the current thread ID (or the process token, if no thread token exists).

MI_AUTH_TYPE_BASIC (MI_T("Basic"))

Uses basic authentication. Requires username/password. Some transports do not support this type of authentication. This authentication type is not very secure.

MI_AUTH_TYPE_KERBEROS (MI_T("Kerberos"))

Username/password optional.

MI_AUTH_TYPE_CLIENT_CERTS (MI_T("ClientCerts"))

Requires certificate thumbprint.

MI_AUTH_TYPE_NTLM (MI_T("Ntlmdomain"))

MI_AUTH_TYPE_ISSUER_CERT (MI_T("IssuerCert"))

Push/Source Initiated subscriptions only.
