// 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 API operations that produce temporary
// credentials, see Requesting Temporary Security Credentials
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html)
// and Comparing the AWS STS API operations
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#stsapi_comparison)
// 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. Session Duration By default, the temporary security credentials
// created by AssumeRoleWithSAML last for one hour. However, you can use the
// optional DurationSeconds parameter to specify the duration of your session. Your
// role session lasts for the duration that you specify, or until the time
// specified in the SAML authentication response's SessionNotOnOrAfter value,
// whichever is shorter. You can provide a DurationSeconds value from 900 seconds
// (15 minutes) up to the maximum session duration setting for the role. This
// setting can have a value from 1 hour to 12 hours. To learn how to view the
// maximum value for your role, see View the Maximum Session Duration Setting for a
// Role
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use.html#id_roles_use_view-role-max-session)
// in the IAM User Guide. The maximum session duration limit applies when you use
// the AssumeRole* API operations or the assume-role* CLI commands. However the
// limit does not apply when you use those operations to create a console URL. For
// more information, see Using IAM Roles
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use.html) in the IAM
// User Guide. Permissions 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 GetFederationToken or
// GetSessionToken API operations. (Optional) You can pass inline or managed
// session policies
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session)
// to this operation. You can pass a single JSON policy document to use as an
// inline session policy. You can also specify up to 10 managed policies to use as
// managed session policies. The plain text that you use for both inline and
// managed session policies can't exceed 2,048 characters. Passing policies to this
// operation returns new temporary credentials. The resulting session's permissions
// are the intersection of the role's identity-based policy and the session
// policies. You can use the role's temporary credentials in subsequent AWS API
// calls to access resources in the account that owns the role. You cannot use
// session policies to grant more permissions than those allowed by the
// identity-based policy of the role that is being assumed. For more information,
// see Session Policies
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session)
// in the IAM User Guide. 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). Tags (Optional) You can
// configure your IdP to pass attributes into your SAML assertion as session tags.
// Each session tag consists of a key name and an associated value. For more
// information about session tags, see Passing Session Tags in STS
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_session-tags.html) in the
// IAM User Guide. You can pass up to 50 session tags. The plain text session tag
// keys can’t exceed 128 characters and the values can’t exceed 256 characters. For
// these and additional limits, see IAM and STS Character Limits
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_iam-limits.html#reference_iam-limits-entity-length)
// in the IAM User Guide. An AWS conversion compresses the passed session policies
// and session tags into a packed binary format that has a separate limit. Your
// request can fail for this limit even if your plain text meets the other
// requirements. The PackedPolicySize response element indicates by percentage how
// close the policies and tags for your request are to the upper size limit. You
// can pass a session tag with the same key as a tag that is attached to the role.
// When you do, session tags override the role's tags with the same key. An
// administrator must grant you the permissions necessary to pass session tags. The
// administrator can also create granular permissions to allow you to pass only
// specific session tags. For more information, see Tutorial: Using Tags for
// Attribute-Based Access Control
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/tutorial_attribute-based-access-control.html)
// in the IAM User Guide. You can set the session tags as transitive. Transitive
// tags persist during role chaining. For more information, see Chaining Roles with
// Session Tags
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_session-tags.html#id_session-tags_role-chaining)
// in the IAM User Guide. SAML Configuration 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. You must also create an IAM role that
// specifies this SAML provider in its trust policy. For more information, see the
// following resources:
