The code can be adapted for use in any C# .NET application. 3 | 4 | ## Prerequisites 5 | 6 | To use the cmdlet, you must have: 7 | 8 | - Active Directory Federation Services (AD FS) correctly integrated with your AWS account for console access using only your organizational credentials. See [Enabling Federation to AWS Using Windows Active Directory, AD FS, and SAML 2.0](http://blogs.aws.amazon.com/security/post/Tx71TWXXJ3UI14/Enabling-Federation-to-AWS-using-Windows-Active-Directory-ADFS-and-SAML-2-0), if you need instructions about this integration. Note that these steps are similar if you're using AD FS 3.0. 9 | - To run, the latest version of the [AWS Tools for Windows PowerShell](https://aws.amazon.com/powershell/) installed on your local workstation. 10 | - To compile, the latest version of the [AWS SDK for .NET](https://aws.amazon.com/sdk-for-net/) installed on your local workstation. 11 | 12 | ## How to compile the PowerShell module 13 | ``` 14 | PS > C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe .\AWSSAMLCredentials\AWSSAMLCredentials.sln /p:Configuration=Release 15 | ``` 16 | 17 | ## How to use the Set-AWSSAMLCredentials cmdlet 18 | 19 | ``` 20 | PS > Import-Module .\AWSSAMLCredentials\ClassLibrary1\bin\Release\AWSSAML.dll 21 | ``` 22 | 23 | Now, let's look at how we authenticate with the AD FS identity provider to obtain temporary AWS credentials. Using the `AWSSAMLCredentials` cmdlet, we can interactively provide Windows Active Directory credentials and then select an AWS role to which the user has access. 24 | 25 | When running the `Set-AWSSAMLCredentials` cmdlet be sure to replace the **example AD FS hostname** with your own actual AD FS hostname. 26 | 27 | ``` 28 | PS > Set-AWSSAMLCredentials -IdentityProviderUrl "https://**adfs.example.com**/adfs/ls/IdpInitiatedSignOn.aspx?loginToRp=urn:amazon:webservices" -UseCurrentCredentials $false 29 | ``` 30 | 31 | ``` 32 | username: adminaduser 33 | password: ************ 34 | domain: example.com 35 | 36 | Please choose the role you would like to assume: 37 | [0]: arn:aws:iam::012345678912:role/ADFS-Production 38 | [1]: arn:aws:iam::012345678912:role/ADFS-Dev 39 | 40 | Selection: 0 41 | ``` 42 | 43 | Rather than typing your Windows credentials every time, the `Set-AWSSAMLCredentials` cmdlet can obtain temporary AWS credentials using your existing Active Directory credentials. 44 | 45 | ``` 46 | PS > Set-AWSSAMLCredentials -IdentityProviderUrl "https://**adfs.example.com**/adfs/ls/IdpInitiatedSignOn.aspx?loginToRp=urn:amazon:webservices" -UseCurrentCredentials $true 47 | ``` 48 | 49 | ``` 50 | Please choose the role you would like to assume: 51 | [0]: arn:aws:iam::012345678912:role/ADFS-Production 52 | [1]: arn:aws:iam::012345678912:role/ADFS-Dev 53 | 54 | Selection: 0 55 | ``` 56 | 57 | To obtain temporary AWS credentials non-interactively, the `RoleIndex` parameter can be used to select an AWS role. In the following command, we obtain temporary credentials by using one of the roles you have pre-configured in AD FS (such as the `ADFS-Production` role [item 0 in the list above]). 58 | 59 | ``` 60 | PS > Set-AWSSAMLCredentials -IdentityProviderUrl "https://**adfs.example.com**/adfs/ls/IdpInitiatedSignOn.aspx?loginToRp=urn:amazon:webservices" -RoleIndex 0 61 | ``` 62 | 63 | Now let's use the temporary AWS credentials obtained by using the `Set-AWSSAMLCredentials` cmdlet to interact with AWS service APIs. 64 | 65 | **Example 1:** In this example, we will list all the available Amazon S3 buckets in the AWS account of the role we have assumed. This is a common task for administrators managing S3 from the Windows PowerShell command line. 66 | ``` 67 | PS > Get-S3Bucket 68 | 69 | CreationDate BucketName 70 | ------------ ---------- 71 | 7/25/2013 3:16:56 AM mybucket1 72 | 4/15/2015 12:46:50 AM mybucket2 73 | 4/15/2015 6:15:53 AM mybucket3 74 | 1/12/2015 11:20:16 PM mybucket4 75 | ``` 76 | 77 | Notice how we didn't need to provide credentials when we called `Get-S3Bucket` cmdlet. Running the `Set-AWSSAMLCredentials` cmdlet has made temporary credentials available to the AWS Tools for Windows in the current PowerShell session. These credentials will expire after 1 hour. When the credentials expire, the Windows PowerShell module can be rerun to refresh the credentials without any user interaction. Note that I have again selected the role using the `RoleIndex` parameter. 78 | 79 | ``` 80 | PS > Set-AWSSAMLCredentials –IdentityProviderUrl "https://**adfs.example.com**/adfs/ls/IdpInitiatedSignOn.aspx?loginToRp=urn:amazon:webservices" -UseCurrentCredentials $true –RoleIndex 0 81 | ``` 82 | 83 | **Example 2:** Now let's list all Amazon EC2 instances in the Sydney region. You may want to do this to get a list of all the EC2 instances in the region in order to manage your EC2 fleet. 84 | 85 | ``` 86 | PS > (Get-Ec2Instance –Region ap-southeast-2).Instances | Select InstanceType, @{Name="Servername";Expression={$\_.tags | where key -eq "Name" | Select Value -Expand Value}} 87 | 88 | InstanceType Servername 89 | ------------ ---------- 90 | t2.small DC2 91 | t1.micro NAT1 92 | t1.micro RDGW1 93 | t1.micro RDGW2 94 | t1.micro NAT2 95 | t2.small DC1 96 | t2.micro BUILD 97 | ``` 98 | 99 | ## License 100 | 101 | This sample application is distributed under the 102 | [Apache License, Version 2.0](http://www.apache.org/licenses/LICENSE-2.0). 103 | 104 | -------------------------------------------------------------------------------- /AWSSAMLCredentials/ClassLibrary1/AWSSAMLUtils.cs: -------------------------------------------------------------------------------- 1 | /* 2 | * Copyright 2010-2013 Amazon.com, Inc. or its affiliates.
