SAML 2.0 SP User Identifying Step

Description

User identifying step for SAML 2.0 single sign-on (SSO) on IAM as service provider (SP).

If the SAML 2.0 handshake was already initiated by the identity provider (IdP), this step consumes the assertion. If no handshake took place yet, this step first initiates an SP-Initiated SSO (and redirects to the IdP) and when returning consumes the assertion.

Properties
SP Entity ID (entityId)
Description
Configures the Unique ID of the Service Provider (SP) used for SP-initiated SSO. In case of SSO initiated by the identity provider (IdP-initiated SSO), the SP is determined by the SAML 2.0 assertion sent by the IdP.

Authentication Method ID (authenticationMethodId)
Description
The identifier of the authentication method for this step. Since the authentication method is also the identifier for failed login attempts for this step, distinct identifiers must be chosen if multiple instances of the same step type are used to check different credentials (e.g., two password step instances check two different passwords).

Example: a system tracks two passwords per user. Password 1 is used in flow A, password 2 in flow B. These two steps must have distinct 'Authentication Method Ids', e.g. PASSWORD1 and PASSWORD2.

If only one identifier (e.g. "PASSWORD") is used, this may allow brute force attacks on the password as follows. Assuming an attacker knows the user's password 1, they get an unlimited number of attempts on flow B, as the 'PASSWORD' counter can repeatedly be reset to 0 by performing a successful login on flow A.

To prevent such attacks, use two different counters by setting the authentication methods, for example, to PASSWORD1 and PASSWORD2, respectively.

Skip Condition (skipCondition)
Description

If this condition is configured and fulfilled, the step is skipped and the flow execution continues with the subsequent step.

Pre Condition (preCondition)
Description
This step is executed only if the configured pre condition is fulfilled. If the condition is not fulfilled, the step and flow execution fail immediately. The step is not initialized and no step method can be called. If no condition is configured, the behavior is that of a fulfilled pre condition.

Requires Activation (requiresActivation)
Description
If enabled, this step is only executed if it has been dynamically activated from a previous step. If it has not been activated, the step is skipped (equivalent to when the skip condition is fulfilled).
Attributes
Boolean
Optional
Default value
false
Tags On Success (tagsOnSuccess)
Description
This step grants these tags if it completes successfully.

Step ID (stepId)
Description
ID of this step. This is only needed if this step is the target of a goto action or if this step requires activation.

On Failure Gotos (onFailureGotos)
Description

If the step fails (no retry) and a goto target for the error code is defined here, the flow does not fail and instead a "goto" to the specified target step is executed. Note that even when the "goto" is executed, any error codes that are considered a failed factor attempt will still increment the "failed attempts" counter, and may lead to the user being locked. Therefore, this may still result in a failed flow.

A typical application of this feature is switching to an alternative authentication factor step, if an external service (e.g. Futurae server, SMS gateway) is not available (error code EXTERNAL_SERVICE_UNAVAILABLE with "Strict Counting" disabled, which will not increment the "failed attempts" counter). Other error codes can be found in the IAM REST documentation, in both the general "Error Codes" section and in the documentation of specific endpoints.

Custom Response Attributes (customResponseAttributes)
Description

A list of custom attributes that are returned in the REST response in addition to the standard attributes the step already returns. The custom attributes defined here are only returned if the step result does not lead to an error response.

Custom attributes are added to the response when a step is initialized and when actions are executed on the step. They will therefore be available in the response leading to this step, and in any responses from endpoints specific to this step. For non-interactive steps, custom attributes are accumulated and added to the response leading to the next interactive step.

Custom attributes are not returned for 'retrieve' endpoints.
