IConnectedIdentityProvider::ConnectIdentity method (identityprovider.h)

  • Article

Connects an identity to a domain user.

Syntax

HRESULT ConnectIdentity(
  [in] BYTE  *AuthBuffer,
  [in] ULONG AuthBufferSize
);

Parameters

[in] AuthBuffer

A marshaled authentication buffer SEC_WINNT_AUTH_IDENTITY_EX2 structure that contains the credential of the online identity. The buffer can be constructed by the caller by using the CredPackAuthenticationBuffer function with the CRED_PACK_ID_PROVIDER_CREDENTIALS option or returned by an online identity credential provider from the CredUIPromptForWindowsCredentials function. The buffer can be optionally encrypted by calling the SspiEncryptAuthIdentityEx function with the SEC_WINNT_AUTH_IDENTITY_ENCRYPT_SAME_LOGON option.

[in] AuthBufferSize

Size, in bytes, of the AuthBuffer parameter.

Return value

If the method succeeds, returns S_OK.

If the method fails, returns a Win32 error code.

Return code Description
S_OK
 The method succeeded.
ERROR_LOGON_FAILURE
 The user name or password is not correct.
ERROR_USER_EXISTS
 The domain user is already connected or associated with an online identity from this provider.
ERROR_INVALID_ACCOUNT_NAME
 The format of the online user name is not valid.

Remarks

The AuthBuffer parameter can be encrypted in the system context if the credential is collected on the secure desktop. In that case, the identity provider cannot decrypt the credential in the current process. To decrypt the buffer, the identity provider will need to send the credential to a process that is running in the system context.
