// 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
// Amazon Web Services 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 Amazon Web Services 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 Amazon Web Services 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. Role chaining
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_terms-and-concepts.html#iam-term-role-chaining)
// limits your CLI or Amazon Web Services API role session to a maximum of one
// hour. When you use the AssumeRole API operation to assume a role, you can
// specify the duration of your role session with the DurationSeconds parameter.
// You can specify a parameter value of up to 43200 seconds (12 hours), depending
// on the maximum session duration setting for your role. However, if you assume a
// role using role chaining and provide a DurationSeconds parameter value greater
// than one hour, the operation fails. Permissions The temporary security
// credentials created by AssumeRoleWithSAML can be used to make API calls to any
// Amazon Web Services 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 plaintext 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 Amazon Web
// Services 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
// Amazon Web Services 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 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 plaintext 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 Amazon Web Services 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 plaintext
// 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 Amazon Web Services. Additionally, you must use
// Identity and Access Management (IAM) to create a SAML provider entity in your
// Amazon Web Services 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:
