Returns a set of temporary security credentials for users who have been authenticated via a SAML authentication response. This operation provides a mechanism for tying an enterprise identity store or directory to role-based AWS access without user-specific credentials or configuration. For a comparison of AssumeRoleWithSAML
with the other APIs that produce temporary credentials, see Requesting Temporary Security Credentials and Comparing the AWS STS APIs in the IAM User Guide.
The temporary security credentials returned by this operation consist of an access key ID, a secret access key, and a security token. Applications can use these temporary security credentials to sign calls to AWS services.
The temporary security credentials are valid for the duration that you specified when calling AssumeRole
, or until the time specified in the SAML authentication response's SessionNotOnOrAfter
value, whichever is shorter. The duration can be from 900 seconds (15 minutes) to a maximum of 3600 seconds (1 hour). The default is 1 hour.
The temporary security credentials created by AssumeRoleWithSAML
can be used to make API calls to any AWS service with the following exception: you cannot call the STS service's GetFederationToken
or GetSessionToken
APIs.
Optionally, you can pass an IAM access policy to this operation. If you choose not to pass a policy, the temporary security credentials that are returned by the operation have the permissions that are defined in the access policy of the role that is being assumed. If you pass a policy to this operation, the temporary security credentials that are returned by the operation have the permissions that are allowed by the intersection of both the access policy of the role that is being assumed, and the policy that you pass. This means that both policies must grant the permission for the action to be allowed. This gives you a way to further restrict the permissions for the resulting temporary security credentials. You cannot use the passed policy to grant permissions that are in excess of those allowed by the access policy of the role that is being assumed. For more information, see Permissions for AssumeRole, AssumeRoleWithSAML, and AssumeRoleWithWebIdentity in the IAM User Guide.
Before your application can call AssumeRoleWithSAML
, you must configure your SAML identity provider (IdP) to issue the claims required by AWS. Additionally, you must use AWS Identity and Access Management (IAM) to create a SAML provider entity in your AWS account that represents your identity provider, and create an IAM role that specifies this SAML provider in its trust policy.
Calling AssumeRoleWithSAML
does not require the use of AWS security credentials. The identity of the caller is validated by using keys in the metadata document that is uploaded for the SAML provider entity for your identity provider.
Calling AssumeRoleWithSAML
can result in an entry in your AWS CloudTrail logs. The entry includes the value in the NameID
element of the SAML assertion. We recommend that you use a NameIDType that is not associated with any personally identifiable information (PII). For example, you could instead use the Persistent Identifier ('urn:oasis:names:tc:SAML:2.0:nameid-format:persistent').

Creating a Request
Creates a value of AssumeRoleWithSAML
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
data AssumeRoleWithSAML Source #
See: assumeRoleWithSAML
smart constructor.
Request Lenses
arwsamlDurationSeconds :: Lens' AssumeRoleWithSAML (Maybe Natural) Source #
The duration, in seconds, of the role session. The value can range from 900 seconds (15 minutes) to 3600 seconds (1 hour). By default, the value is set to 3600 seconds. An expiration can also be specified in the SAML authentication response's SessionNotOnOrAfter
value. The actual expiration time is whichever value is shorter.
This is separate from the duration of a console session that you might request using the returned credentials. The request to the federation endpoint for a console sign-in token takes a SessionDuration
parameter that specifies the maximum length of the console session, separately from the DurationSeconds
parameter on this API. For more information, see Enabling SAML 2.0 Federated Users to Access the AWS Management Console in the IAM User Guide.
arwsamlPolicy :: Lens' AssumeRoleWithSAML (Maybe Text) Source #
An IAM policy in JSON format.
The policy parameter is optional. If you pass a policy, the temporary security credentials that are returned by the operation have the permissions that are allowed by both the access policy of the role that is being assumed, and the policy that you pass. This gives you a way to further restrict the permissions for the resulting temporary security credentials. You cannot use the passed policy to grant permissions that are in excess of those allowed by the access policy of the role that is being assumed. For more information, Permissions for AssumeRole, AssumeRoleWithSAML, and AssumeRoleWithWebIdentity in the IAM User Guide.
The format for this parameter, as described by its regex pattern, is a string of characters up to 2048 characters in length. The characters can be any ASCII character from the space character to the end of the valid character list (\u0020-\u00FF). It can also include the tab (\u0009), linefeed (\u000A), and carriage return (\u000D) characters.
The policy plain text must be 2048 bytes or shorter. However, an internal conversion compresses it into a packed binary format with a separate limit. The PackedPolicySize response element indicates by percentage how close to the upper size limit the policy is, with 100% equaling the maximum allowed size.
arwsamlRoleARN :: Lens' AssumeRoleWithSAML Text Source #
The Amazon Resource Name (ARN) of the role that the caller is assuming.
arwsamlPrincipalARN :: Lens' AssumeRoleWithSAML Text Source #
The Amazon Resource Name (ARN) of the SAML provider in IAM that describes the IdP.
arwsamlSAMLAssertion :: Lens' AssumeRoleWithSAML Text Source #
The base-64 encoded SAML authentication response provided by the IdP.
For more information, see Configuring a Relying Party and Adding Claims in the Using IAM guide.
Destructuring the Response
assumeRoleWithSAMLResponse Source #
Creates a value of AssumeRoleWithSAMLResponse
with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
data AssumeRoleWithSAMLResponse Source #
Contains the response to a successful AssumeRoleWithSAML request, including temporary AWS credentials that can be used to make AWS requests.
See: assumeRoleWithSAMLResponse
smart constructor.
Response Lenses
arwsamlrsSubject :: Lens' AssumeRoleWithSAMLResponse (Maybe Text) Source #
The value of the NameID
element in the Subject
element of the SAML assertion.
arwsamlrsAudience :: Lens' AssumeRoleWithSAMLResponse (Maybe Text) Source #
The value of the Recipient
attribute of the SubjectConfirmationData
element of the SAML assertion.
arwsamlrsPackedPolicySize :: Lens' AssumeRoleWithSAMLResponse (Maybe Natural) Source #
A percentage value that indicates the size of the policy in packed form. The service rejects any policy with a packed size greater than 100 percent, which means the policy exceeded the allowed space.
arwsamlrsCredentials :: Lens' AssumeRoleWithSAMLResponse (Maybe Credentials) Source #
The temporary security credentials, which include an access key ID, a secret access key, and a security (or session) token.
Note: The size of the security token that STS APIs return is not fixed. We strongly recommend that you make no assumptions about the maximum size. As of this writing, the typical size is less than 4096 bytes, but that can vary. Also, future updates to AWS might require larger sizes.
arwsamlrsSubjectType :: Lens' AssumeRoleWithSAMLResponse (Maybe Text) Source #
The format of the name ID, as defined by the Format
attribute in the NameID
element of the SAML assertion. Typical examples of the format are transient
or persistent
.
If the format includes the prefix 'urn:oasis:names:tc:SAML:2.0:nameid-format', that prefix is removed. For example, 'urn:oasis:names:tc:SAML:2.0:nameid-format:transient' is returned as transient
. If the format includes any other prefix, the format is returned with no modifications.
arwsamlrsNameQualifier :: Lens' AssumeRoleWithSAMLResponse (Maybe Text) Source #
A hash value based on the concatenation of the Issuer
response value, the AWS account ID, and the friendly name (the last part of the ARN) of the SAML provider in IAM. The combination of NameQualifier
and Subject
can be used to uniquely identify a federated user.
The following pseudocode shows how the hash value is calculated:
'BASE64 ( SHA1 ( "https://example.com/saml" + "123456789012" + "/MySAMLIdP" ) )'
arwsamlrsAssumedRoleUser :: Lens' AssumeRoleWithSAMLResponse (Maybe AssumedRoleUser) Source #
The identifiers for the temporary security credentials that the operation returns.
arwsamlrsIssuer :: Lens' AssumeRoleWithSAMLResponse (Maybe Text) Source #
The value of the Issuer
element of the SAML assertion.
arwsamlrsResponseStatus :: Lens' AssumeRoleWithSAMLResponse Int Source #
The response status code.
