Description:

stormawsadfs 1.0.0

storm-aws-adfs
Fork of aws-adfs
Original doc:



The project provides command line tool - aws-adfs to ease AWS cli authentication against ADFS (multi factor authentication with active directory).
aws-adfs command line tool


allows you to re-login to STS without entering credentials for an extended period of time, without having to store the user's actual credentials. It also lets an organization control the period in which a user can re-login to STS without entering credentials, by altering the ADFS session lifetime.


supports automation tools like ansible by providing security token in AWS_SESSION_TOKEN/AWS_SECURITY_TOKEN environment variables.


supports using Security Support Provider Interface (SSPI) on Windows OS.


MFA integration
aws-adfs integrates with:

duo security MFA provider with support for FIDO U2F (CTAP1) / FIDO2 (CTAP2) hardware authenticators
Symantec VIP MFA provider
RSA SecurID MFA provider

Examples of usage
aws-adfs


login to your adfs host with disabled ssl verification on aws cli profile: adfs
aws-adfs login --adfs-host=your-adfs-hostname --no-ssl-verification

and verification
aws --profile=adfs s3 ls



login to your adfs host with disabled ssl verification on specified aws cli profile: specified-profile
aws-adfs login --profile=specified-profile --adfs-host=your-adfs-hostname --no-ssl-verification

and verification
aws --profile=specified-profile s3 ls



login to your adfs host and fetch roles for AWS GovCloud (US)
aws-adfs login --adfs-host=your-adfs-hostname --provider-id urn:amazon:webservices:govcloud --region us-gov-west-1

and verification
aws s3 ls



login to your adfs host within ansible playbook
---
- name: "Auth sts aws"
command: "aws-adfs login --adfs-host sts.example.com --env --stdout --role-arn arn:aws:iam::000123456789:role/ADMIN"
register: sts_result
environment:
- username: "{{ ansible_user }}@example.com"
- password: "{{ ansible_ssh_pass }}"

- name: "Set sts facts"
set_fact:
sts: "{{ sts_result.stdout | from_json }}"

- name: "List s3 Buckets"
aws_s3_bucket_facts:
aws_access_key: "{{ sts.AccessKeyId }}"
aws_secret_key: "{{ sts.SecretAccessKey }}"
security_token: "{{ sts.SessionToken }}"
region: "us-east-1"
register: buckets

- name: "Print Buckets"
debug:
var: buckets



login to your adfs host by passing username and password credentials via a file
aws-adfs login --adfs-host=your-adfs-hostname --authfile=/path/and/file/name

Auth file should be in format of
[profile_name]
username = your_username
password = your_password



.aws/config profile for automatically refreshing credentials
[profile example-role-ue1]
credential_process=aws-adfs login --region=us-east-1 --role-arn=arn:aws:iam::1234567891234:role/example-role --adfs-host=adfs.example.com --stdout

Warning: see AWS documentation about security considerations to take when sourcing credentials with an external process.

Known issues


duo-security
Error: Cannot begin authentication process. The error response: {"message": "Unknown authentication method.", "stat": "FAIL"}
Please setup preferred auth method in duo-security settings (settings' -> 'My Settings & Devices').


USB FIDO2 does not work in Windows Subsystem for Linux (WSL)
OSError: [Errno 2] No such file or directory: '/sys/class/hidraw'
USB devices are not accessible in WSL, please install and run aws-adfs on the Windows 10 host and then access the credentials in WSL from the filesystem. Example:
export AWS_CONFIG_FILE=/mnt/c/Users/username/.aws/config
export AWS_SHARED_CREDENTIALS_FILE=/mnt/c/Users/username/.aws/credentials



FIDO2 devices are not detected on Windows 10 build 1903 or newer
Running aws-adfs as Administrator is required since Windows 10 build 1903 to access FIDO2 devices, cf. https://github.com/Yubico/python-fido2/issues/55)
