type AssumeRoleWithSAMLInput struct { DurationSeconds *int64 `min:"900" type:"integer"` Policy *string `min:"1" type:"string"` PrincipalArn *string `min:"20" type:"string" required:"true"` RoleArn *string `min:"20" type:"string" required:"true"` SAMLAssertion *string `min:"4" type:"string" required:"true"` }


Type: *int64

The duration, in seconds, of the role session. Your role session lasts for the duration that you specify for the DurationSeconds parameter, 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. If you specify a value higher than this setting, the operation fails. For example, if you specify a session duration of 12 hours, but your administrator set the maximum session duration to 6 hours, your operation fails. To learn how to view the maximum value for your role, see View the Maximum Session Duration Setting for a Role ( in the IAM User Guide.

By default, the value is set to 3600 seconds.

The DurationSeconds parameter 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. For more information, see Creating a URL that Enables Federated Users to Access the AWS Management Console ( in the IAM User Guide.


Type: *string

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.


Type: *string

The Amazon Resource Name (ARN) of the SAML provider in IAM that describes the IdP.

PrincipalArn is a required field


Type: *string

The Amazon Resource Name (ARN) of the role that the caller is assuming.

RoleArn is a required field


Type: *string

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.

SAMLAssertion is a required field



func (s AssumeRoleWithSAMLInput) GoString() string

GoString returns the string representation
