14// Returns a set of temporary security credentials for users who have been
15// authenticated via a SAML authentication response. This operation provides a
16// mechanism for tying an enterprise identity store or directory to role-based
17// Amazon Web Services access without user-specific credentials or configuration.
18// For a comparison of AssumeRoleWithSAML with the other API operations that
19// produce temporary credentials, see [Requesting Temporary Security Credentials]and [Comparing the Amazon Web Services STS API operations] in the IAM User Guide.
20//
21// The temporary security credentials returned by this operation consist of an
22// access key ID, a secret access key, and a security token. Applications can use
23// these temporary security credentials to sign calls to Amazon Web Services
24// services.
25//
26// # Session Duration
27//
28// By default, the temporary security credentials created by AssumeRoleWithSAML
29// last for one hour. However, you can use the optional DurationSeconds parameter
30// to specify the duration of your session. Your role session lasts for the
31// duration that you specify, or until the time specified in the SAML
32// authentication response's SessionNotOnOrAfter value, whichever is shorter. You
33// can provide a DurationSeconds value from 900 seconds (15 minutes) up to the
34// maximum session duration setting for the role. This setting can have a value
35// from 1 hour to 12 hours. To learn how to view the maximum value for your role,
36// see [View the Maximum Session Duration Setting for a Role]in the IAM User Guide. The maximum session duration limit applies when you
37// use the AssumeRole* API operations or the assume-role* CLI commands. However
38// the limit does not apply when you use those operations to create a console URL.
39// For more information, see [Using IAM Roles]in the IAM User Guide.
40//
41// [Role chaining]limits your CLI or Amazon Web Services API role session to a maximum of one
42// hour. When you use the AssumeRole API operation to assume a role, you can
43// specify the duration of your role session with the DurationSeconds parameter.
44// You can specify a parameter value of up to 43200 seconds (12 hours), depending
45// on the maximum session duration setting for your role. However, if you assume a
46// role using role chaining and provide a DurationSeconds parameter value greater
47// than one hour, the operation fails.
48//
49// # Permissions
50//
51// The temporary security credentials created by AssumeRoleWithSAML can be used to
52// make API calls to any Amazon Web Services service with the following exception:
53// you cannot call the STS GetFederationToken or GetSessionToken API operations.
54//
55// (Optional) You can pass inline or managed [session policies] to this operation. You can pass a
56// single JSON policy document to use as an inline session policy. You can also
57// specify up to 10 managed policy Amazon Resource Names (ARNs) to use as managed
58// session policies. The plaintext that you use for both inline and managed session
59// policies can't exceed 2,048 characters. Passing policies to this operation
60// returns new temporary credentials. The resulting session's permissions are the
61// intersection of the role's identity-based policy and the session policies. You
62// can use the role's temporary credentials in subsequent Amazon Web Services API
63// calls to access resources in the account that owns the role. You cannot use
64// session policies to grant more permissions than those allowed by the
65// identity-based policy of the role that is being assumed. For more information,
66// see [Session Policies]in the IAM User Guide.
67//
68// Calling AssumeRoleWithSAML does not require the use of Amazon Web Services
69// security credentials. The identity of the caller is validated by using keys in
70// the metadata document that is uploaded for the SAML provider entity for your
71// identity provider.
72//
73// Calling AssumeRoleWithSAML can result in an entry in your CloudTrail logs. The
74// entry includes the value in the NameID element of the SAML assertion. We
75// recommend that you use a NameIDType that is not associated with any personally
76// identifiable information (PII). For example, you could instead use the
77// persistent identifier ( urn:oasis:names:tc:SAML:2.0:nameid-format:persistent ).
78//
79// # Tags
80//
81// (Optional) You can configure your IdP to pass attributes into your SAML
82// assertion as session tags. Each session tag consists of a key name and an
83// associated value. For more information about session tags, see [Passing Session Tags in STS]in the IAM User
84// Guide.
85//
86// You can pass up to 50 session tags. The plaintext session tag keys canβt exceed
87// 128 characters and the values canβt exceed 256 characters. For these and
88// additional limits, see [IAM and STS Character Limits]in the IAM User Guide.
89//
90// An Amazon Web Services conversion compresses the passed inline session policy,
91// managed policy ARNs, and session tags into a packed binary format that has a
92// separate limit. Your request can fail for this limit even if your plaintext
93// meets the other requirements. The PackedPolicySize response element indicates
94// by percentage how close the policies and tags for your request are to the upper
95// size limit.
96//
97// You can pass a session tag with the same key as a tag that is attached to the
98// role. When you do, session tags override the role's tags with the same key.
99//
100// An administrator must grant you the permissions necessary to pass session tags.
101// The administrator can also create granular permissions to allow you to pass only
102// specific session tags. For more information, see [Tutorial: Using Tags for Attribute-Based Access Control]in the IAM User Guide.
103//
104// You can set the session tags as transitive. Transitive tags persist during role
105// chaining. For more information, see [Chaining Roles with Session Tags]in the IAM User Guide.
106//
107// # SAML Configuration
108//
109// Before your application can call AssumeRoleWithSAML , you must configure your
110// SAML identity provider (IdP) to issue the claims required by Amazon Web
111// Services. Additionally, you must use Identity and Access Management (IAM) to
112// create a SAML provider entity in your Amazon Web Services account that
113// represents your identity provider. You must also create an IAM role that
114// specifies this SAML provider in its trust policy.
