我尝试设置SimpleSAMLphp IdP以向我的本地开发服务器发送SAML响应(在本例中为SP启动的流)。此IdP基于来自https://hub.docker.com/r/kristophjunge/test-saml-idp/的Docker镜像(我相信版本1.15)。
整个设置是模拟我所拥有的类似环境,即G Suite IdP用于同一个本地开发者SP - 尝试最终消除本地开发环境中的云依赖关系,并用等效的SimpleSAMLphp替换它。 / p>
我遇到的问题是Google在其SAML响应中发送了NameId:
<saml2:Subject>
<saml2:NameID Format="urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified">a.b@c.com</saml2:NameID>
<saml2:SubjectConfirmation Method="urn:oasis:names:tc:SAML:2.0:cm:bearer">
<saml2:SubjectConfirmationData InResponseTo="ONELOGIN_88ebd953f02c07d01b19714cd70133827ff1228e" NotOnOrAfter="2018-05-07T20:21:25.433Z" . Recipient="https://ee0138c4.ngrok.io/saml/?acs" />
</saml2:SubjectConfirmation>
</saml2:Subject>
但是SimpleSAMLphp会以这种格式发送它:
<saml:Subject>
<saml:NameID SPNameQualifier="https://ee0138c4.ngrok.io/saml/metadata" Format="urn:oasis:names:tc:SAML:2.0:nameid-format:transient">_69d05500bd6e797de3674df0165facbfa0af699589</saml:NameID>
<saml:SubjectConfirmation Method="urn:oasis:names:tc:SAML:2.0:cm:bearer"> <saml:SubjectConfirmationData NotOnOrAfter="2018-05-09T17:47:57Z" Recipient="https://ee0138c4.ngrok.io/saml/?acs" InResponseTo="ONELOGIN_170bb7a0ff82100318ba498583e8e59cdae8607b" />
</saml:SubjectConfirmation>
</saml:Subject>
我需要它作为属性值
( a.b@c.com 而不是 _69d05500bd6e797de3674df0165facbfa0af699589 )
然后我可以在我的SP逻辑中抓取它,而不是发送一些随机数,我假设它是一个transientId。
以下是我的配置:
启动Docker容器:
docker run --name=testsamlidp_idp \
-p 8080:8080 \
-p 8443:8443 \
-e SIMPLESAMLPHP_SP_ENTITY_ID=https://ee0138c4.ngrok.io/saml/metadata \
-e SIMPLESAMLPHP_SP_ASSERTION_CONSUMER_SERVICE=https://ee0138c4.ngrok.io/saml/?acs \
-e SIMPLESAMLPHP_SP_SINGLE_LOGOUT_SERVICE=http://localhost/simplesaml/module.php/saml/sp/saml2-logout.php/test-sp \
-v $(pwd)/users.php:/var/www/simplesamlphp/config/authsources.php \
-v $(pwd)/_saml20-sp-remote.php:/var/www/simplesamlphp/config/saml20-sp-remote.php \
-d kristophjunge/test-saml-idp
users.php 包含:
<?php
$config = array(
'admin' => array(
'core:AdminPassword',
),
'example-userpass' => array(
'exampleauth:UserPass',
'user1:user1pass' => array(
'uid' => array('1'),
'Groups' => array('group1','group2', 'group3'),
'email' => 'user1@example.com',
),
'user2:user2pass' => array(
'uid' => array('2'),
'Groups' => array('group2', 'group4', 'group5'),
'email' => 'user2@example.com',
),
),
);
和 _saml20-sp-remote.php 是:
<?php
/**
* SAML 2.0 remote SP metadata for SimpleSAMLphp.
*
* See: https://simplesamlphp.org/docs/stable/simplesamlphp-reference-sp-remote
*/
$metadata[getenv('SIMPLESAMLPHP_SP_ENTITY_ID')] = array(
'AssertionConsumerService' => getenv('SIMPLESAMLPHP_SP_ASSERTION_CONSUMER_SERVICE'),
'SingleLogoutService' => getenv('SIMPLESAMLPHP_SP_SINGLE_LOGOUT_SERVICE'),
#'NameIDFormat' => 'urn:oasis:names:tc:SAML:1.1:nameid-format:persistent',
#'simplesaml.nameidattribute' => 'email',
#'simplesaml.attributes' => FALSE,
'authproc.idp' => array(
/* Filter to create a NameID with the "unspecified" format. */
3 => array(
'class' => 'saml:AtrributeNameID',
'attribute' => 'email',
'Format' => 'urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress',
),
),
/* Select the unspecified NameID format by default. */
'NameIDFormat' => 'urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified',
);
我假设在后一个文件中出现了某种错误配置,也许有人可以帮助我找到它的底部。
提前谢谢。

以下设置对我有用:
docker run --name=testsamlidp_idp \
-p 8080:8080 \
-p 8443:8443 \
-e SIMPLESAMLPHP_SP_ENTITY_ID=https://ee0138c4.ngrok.io/saml/metadata \
-e SIMPLESAMLPHP_SP_ASSERTION_CONSUMER_SERVICE=https://ee0138c4.ngrok.io/saml/?acs \
-e SIMPLESAMLPHP_SP_SINGLE_LOGOUT_SERVICE=http://localhost/simplesaml/module.php/saml/sp/saml2-logout.php/test-sp \
-v $(pwd)/users.php:/var/www/simplesamlphp/config/authsources.php \
-v $(pwd)/saml20-idp-hosted.php:/var/www/simplesamlphp/metadata/saml20-idp-hosted.php \
-d kristophjunge/test-saml-idp
Docker容器中saml20-idp-hosted.php
中的/var/www/simplesamlphp/metadata/saml20-idp-hosted.php
<?php
$metadata['__DYNAMIC:1__'] = array(
/*
* The hostname of the server (VHOST) that will use this SAML entity.
*
* Can be '__DEFAULT__', to use this entry by default.
*/
'host' => '__DEFAULT__',
// X.509 key and certificate. Relative to the cert directory.
'privatekey' => 'server.pem',
'certificate' => 'server.crt',
/*
* Authentication source to use. Must be one that is configured in
* 'config/authsources.php'.
*/
'auth' => 'example-userpass',
'NameIDFormat' => 'urn:oasis:names:tc:SAML:2.0:nameid-format:persistent',
// refer to https://simplesamlphp.org/docs/stable/saml:nameid
'authproc' => array(
3 => array(
'class' => 'saml:AttributeNameID',
'attribute' => 'email',
'Format' => 'urn:oasis:names:tc:SAML:2.0:nameid-format:persistent',
),
),
);
NameIDFormat
和Format
都是必需的。 email
应与
authsources.php
中的/var/www/simplesamlphp/config
:<?php
$config = array(
'admin' => array(
'core:AdminPassword',
),
'example-userpass' => array(
'exampleauth:UserPass',
'user1:user1pass' => array(
'uid' => array('1'),
'Groups' => array('group1','group2', 'group3'),
'email' => 'user1@example.com',
),
'user2:user2pass' => array(
'uid' => array('2'),
'Groups' => array('group2', 'group4', 'group5'),
'email' => 'user2@example.com',
),
),
);
关于如何实现它的一般想法是有点documented 但是文件不适合胆小的人,当然也欢迎有关为什么事情就是这样的理由的部分。
