IRTCProfile2::AllowedAuth (Windows CE 5.0)
This method sets or gets the allowed authentication methods for the profile. When the server issues a challenge to a request from the client (using this profile), the values returned by this method specify the authentication protocols that are allowed for a response to that challenge.
HRESULT put_AllowedAuth( long lAllowedAuth);HRESULT get_AllowedAuth( long* plAllowedAuth);
Parameters
- lAllowedAuth, plAllowedAuth
[in, out] The permitted authentication value. The value can be any combination of the RTCAU_ constants.
Return Values
RTC methods can return an RTC_E_ constant. The following table shows additional return values and additional information about specific return values.
| Value | Meaning |
|---|---|
| E_POINTER | The plAllowedAuth parameter is not a valid pointer. |
| E_INVALIDARG | The lAllowedAuth parameter is not in the valid range, or the flags contain the RTCAU_USE_LOGON_CRED flag and none of the Authentication methods is enabled. |
| RTC_E_UDP_NOT_SUPPORTED | The authentication specified in the lAllowedAuth parameter contains either NTLM, Kerberos, or USE_LOGON_CRED, which are not supported if any of the servers in the profile has specified the UDP transport. |
| RTC_E_INVALID_REGISTRATION_STATE | The profile is registered such that the allowed authentication schemes cannot be changed. The profile must not be in one of the following three states: RTCRS_REGISTERED, RTCRS_UNREGISTERING, or RTCRS_REGISTERING. |
| RTC_E_BASIC_AUTH_SET_TLS | The transport must be set to TLS if basic authentication is allowed. |
Remarks
The following list provides the transport types that are allowed for each of the supported authentication methods:
- Basic — Requires the TLS transport. This authentication method will be rejected if TLS is not specified in the profile.
- Digest — Supported over the TCP, TLS, or UDP transport.
- Kerberos — Supported over the TCP or TLS transport. This authentication method is rejected if UDP is specified as the transport in the profile.
- NTLM — Supported over the TCP or TLS transport. This authentication method is rejected if UDP is specified as the transport in the profile.
- USE_LOGON_CRED — Supported over the TCP or TLS transport. This authentication method is rejected if UDP is specified as the transport in the profile. This authentication method requires that at least one of the other authentication methods be present in the profile; otherwise, E_INVALIDARG is returned.
When setting the authentication methods:
- If an authentication method is not specified in the plAllowedAuth flag, the RTC Client API does not use that method.
- If the server does not challenge the client, the plAllowedAuth flag has no effect.
