CLI tool which enables you to login and retrieve AlibabaCloud temporary credentials using with ADFS or PingFederate Identity Providers.
This is based on saml2aws. Great thanks to Versent's work.
The process goes something like this:
- Setup an account alias, either using the default or given a name
- Prompt user for credentials
- Log in to Identity Provider using form based authentication
- Build a SAML assertion containing AlibabaCloud RAM roles
- Exchange the role and SAML assertion with AlibabaCloud STS service to get a temporary set of credentials
- Save these credentials to an AlibabaCloud CLI profile named "saml"

Aside from Okta, most of the providers in this project are using screen scraping to log users into SAML, this isn't ideal and hopefully vendors make this easier in the future. In addition to this there are some things you need to know:
- AlibabaCloud defaults to session tokens being issued with a duration of up to 3600 seconds (1 hour), this can now be configured as Set the maximum session duration for a RAM role.
- Every SAML provider is different, the login process, MFA support is pluggable and therefore some work may be needed to integrate with your identity server

If you use eval $(saml2alibabacloud script) frequently, you may want to create a alias for it:
zsh:
alias s2a="function(){eval $( $(command saml2alibabacloud) script --shell=bash --profile=$@);}"
bash:
function s2a { eval $( $(which saml2alibabacloud) script --shell=bash --profile=$@); }
If the exec sub-command is called, saml2alibabacloud will execute the command given as an argument:
By default saml2alibabacloud will execute the command with temp credentials generated via saml2alibabacloud login.
The --exec-profile flag allows for a command to execute using an AlibabaCloud CLI profile which may have chained
"assume role" actions. (via 'source_profile' in ~/.aliyun/config.json)
options:
--exec-profile Execute the given command utilizing a specific profile from your ~/.aliyun/config.json file
This is the new way of adding IDP provider accounts, it enables you to have named accounts with whatever settings you like and supports having one default account which is used if you omit the account flag. This replaces the --provider flag and old configuration file in 1.x.
To add a default IdP account to saml2alibabacloud just run the following command and follow the prompts.
$ saml2alibabacloud configure
? Please choose a provider: Ping
? AlibabaCloud CLI Profile myaccount
? URL https://example.com
? Username [email protected]
? Password
No password supplied
account {
URL: https://example.com
Username: [email protected]
Provider: Ping
MFA: Auto
SkipVerify: false
AlibabaCloudURN: urn:alibaba:cloudcomputing
SessionDuration: 3600
Profile: myaccount
Region: us-east-1
}
Configuration saved for IDP account: default
Then to login using this account.
saml2alibabacloud login
You can also add named accounts, below is an example where I am setting up an account under the wolfeidau alias, again just follow the prompts.
saml2alibabacloud configure -a wolfeidau
You can also configure the account alias without prompts.
saml2alibabacloud configure -a wolfeidau --idp-provider KeyCloak --username [email protected] -r cn-north-1 \
--url https://keycloak.wolfe.id.au/auth/realms/master/protocol/saml/clients/alibabacloud --skip-prompt
Then your ready to use saml2alibabacloud.

Configuring multiple accounts with custom role and profile in ~/.aliyun/config.json with goal being isolation between infra code when deploying to these environments. This setup assumes you're using separate roles and probably AlibabaCloud accounts for dev and test and is designed to help operations staff avoid accidentally deploying to the wrong AlibabaCloud account in complex environments. Note that this method configures SAML authentication to each AlibabaCloud account directly (in this case different AlibabaCloud accounts). In the example below, separate authentication values are configured for AlibabaCloud accounts 'profile=customer-dev/Account=was 121234567890' and 'profile=customer-test/Account=121234567891'
To setup the dev account run the following and enter URL, username and password, and assign a standard role to be automatically selected on login.
saml2alibabacloud configure -a customer-dev --role=acs:ram::121234567890:role/customer-admin-role -p customer-dev
This will result in the following configuration in ~/.saml2alibabacloud.
[customer-dev]
url = https://id.customer.cloud
username = [email protected]
provider = Ping
mfa = Auto
skip_verify = false
timeout = 0
alibabacloud_urn = urn:alibaba:cloudcomputing
alibabacloud_session_duration = 28800
alibabacloud_profile = customer-dev
role_arn = acs:ram::121234567890:role/customer-admin-role
region = cn-hangzhou
To use this you will need to export ALIBABACLOUD_DEFAULT_PROFILE=customer-dev environment variable to target dev.
To setup the test account run the following and enter URL, username and password.
saml2alibabacloud configure -a customer-test --role=acs:ram::121234567891:role/customer-admin-role -p customer-test
This results in the following configuration in ~/.saml2alibabacloud.
[customer-test]
url = https://id.customer.cloud
username = [email protected]
provider = Ping
mfa = Auto
skip_verify = false
timeout = 0
alibabacloud_urn = urn:alibaba:cloudcomputing
alibabacloud_session_duration = 28800
alibabacloud_profile = customer-test
role_arn = acs:ram::121234567891:role/customer-admin-role
region = cn-hangzhou
To use this you will need to export ALIBABACLOUD_DEFAULT_PROFILE=customer-test environment variable to target test.
There are few additional parameters allowing to customise saml2alibabacloud configuration.
Use following parameters in ~/.saml2alibabacloud file:
http_attempts_count- configures the number of attempts to send http requests in order to authorise with saml provider. Defaults to 1http_retry_delay- configures the duration (in seconds) of timeout between attempts to send http requests to saml provider. Defaults to 1region- configures which region endpoints to use. Defaults tocn-hangzhou
Example: typical configuration with such parameters would look like follows:
[default]
url = https://id.customer.cloud
username = [email protected]
provider = Ping
mfa = Auto
skip_verify = false
timeout = 0
alibabacloud_urn = urn:alibaba:cloudcomputing
alibabacloud_session_duration = 28800
alibabacloud_profile = customer-dev
role_arn = acs:ram::121234567890:role/customer-admin-role
http_attempts_count = 3
http_retry_delay = 1
region = cn-hangzhou
To build this software on osx clone to the repo to $GOPATH/src/github.com/aliyun/saml2alibabacloud and ensure you have $GOPATH/bin in your $PATH.
make mod
Install the binary to $GOPATH/bin.
make install
Then to test the software just run.
make test
The exec sub command will export the following environment variables.
- ALICLOUD_ACCESS_KEY
- ALICLOUD_SECRET_KEY
- ALICLOUD_SECURITY_TOKEN
- ALICLOUD_ASSUME_ROLE_SESSION_NAME
- ALICLOUD_PROFILE
Note: That profile environment variables enable you to use exec with a script or command which requires an explicit profile.
This tool would not be possible without some great opensource libraries.
- saml2aws saml2aws
- goquery html querying
- etree xpath selector
- kingpin command line flags
- go-ini INI file parser
- go-ntlmssp NTLM/Negotiate authentication
Install github-release.
go get github.com/buildkite/github-release

There are two levels of debugging, first emits debug information and the URL / Method / Status line of requests.
saml2alibabacloud login --verbose
The second emits the content of requests and responses, this includes authentication related information so don't copy and paste it into chat or tickets!
