title: Amazon Web Services
|
||
---
|
||
|
||
## What is AWS
|
||
|
||
:::note
|
||
Amazon Web Services (AWS) is the world’s most comprehensive and broadly adopted cloud platform, offering over 175 fully featured services from data centers globally. Millions of customers—including the fastest-growing startups, largest enterprises, and leading government agencies—are using AWS to lower costs, become more agile, and innovate faster.
|
||
:::
|
||
|
||
## Preparation
|
||
|
||
The following placeholders will be used:
|
||
|
||
- `passbook.company` is the FQDN of the passbook install.
|
||
|
||
Create an application in passbook and note the slug, as this will be used later. Create a SAML provider with the following parameters:
|
||
|
||
- ACS URL: `https://signin.aws.amazon.com/saml`
|
||
- Audience: `urn:amazon:webservices`
|
||
- Issuer: `passbook`
|
||
- Binding: `Post`
|
||
|
||
You can of course use a custom signing certificate, and adjust durations.
|
||
|
||
## AWS
|
||
|
||
Create a role with the permissions you desire, and note the ARN.
|
||
|
||
After you've created the Property Mappings below, add them to the Provider.
|
||
|
||
Create an application, assign policies, and assign this provider.
|
||
|
||
Export the metadata from passbook, and create an Identity Provider [here](https://console.aws.amazon.com/iam/home#/providers).
|
||
|
||
#### Role Mapping
|
||
|
||
The Role mapping specifies the AWS ARN(s) of the identity provider, and the role the user should assume ([see](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_providers_create_saml_assertions.html#saml_role-attribute)).
|
||
|
||
This Mapping needs to have the SAML Name field set to "https://aws.amazon.com/SAML/Attributes/Role"
|
||
|
||
As expression, you can return a static ARN like so
|
||
|
||
```python
|
||
return "arn:aws:iam::123412341234:role/saml_role,arn:aws:iam::123412341234:saml-provider/passbook"
|
||
```
|
||
|
||
Or, if you want to assign AWS Roles based on Group membership, you can add a custom attribute to the Groups, for example "aws_role", and use this snippet below. Groups are sorted by name and later groups overwrite earlier groups' attributes.
|
||
|
||
```python
|
||
role_name = user.group_attributes().get("aws_role", "")
|
||
return f"arn:aws:iam::123412341234:role/{role_name},arn:aws:iam::123412341234:saml-provider/passbook"
|
||
```
|
||
|
||
If you want to allow a user to choose from multiple roles, use this snippet
|
||
|
||
```python
|
||
return [
|
||
"arn:aws:iam::123412341234:role/role_a,arn:aws:iam::123412341234:saml-provider/passbook",
|
||
"arn:aws:iam::123412341234:role/role_b,arn:aws:iam::123412341234:saml-provider/passbook",
|
||
"arn:aws:iam::123412341234:role/role_c,arn:aws:iam::123412341234:saml-provider/passbook",
|
||
]
|
||
```
|
||
|
||
### RoleSessionName Mapping
|
||
|
||
The RoleSessionMapping specifies what identifier will be shown at the top of the Management Console ([see](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_providers_create_saml_assertions.html#saml_role-session-attribute)).
|
||
|
||
This mapping needs to have the SAML Name field set to "https://aws.amazon.com/SAML/Attributes/RoleSessionName".
|
||
|
||
To use the user's username, use this snippet
|
||
|
||
```python
|
||
return user.username
|
||
```
