+# SimpleSamlPHP as Gerrit SAML provider
+
+[SimpleSamlPHP](https://simplesamlphp.org/) is open source Identity and Access
+Management tool and supports the SAML authentication protocol.
+
+## Objective
+
+This document provides a step-by-step tutorial how to set-up SimpleSamlPHP as
+SAML provider for Gerrit Code Review for development and guidance only.
+For production HTTPS protocol and other more secure credentials and keys
+would need to be put in place.
+
+## Prerequisites
+
+- [Docker](https://www.docker.com/get-started)
+- [Gerrit Code Review v2.15 or later](https://www.gerritcodereview.com)
+
+## Steps
+
+1. Install the `jamedjo/test-saml-idp` docker image:
+
+```bash
+docker run -it --rm --name=testsamlidp_idp \
+	-p 8080:8080 \
+	-p 8443:8443 \
+	-v $(realpath simplesamlphp/config/authsources.php):/var/www/simplesamlphp/config/authsources.php \
+	-v $(realpath simplesamlphp/config/config.php):/var/www/simplesamlphp/config/config.php \
+	-v $(realpath simplesamlphp/metadata/saml20-sp-remote.php):/var/www/simplesamlphp/metadata/saml20-sp-remote.php \
+	-v $(realpath simplesamlphp/metadata/saml20-idp-hosted.php):/var/www/simplesamlphp/metadata/saml20-idp-hosted.php \
+	-e SIMPLESAMLPHP_SP_ENTITY_ID=gerritSaml \
+	-e SIMPLESAMLPHP_SP_ASSERTION_CONSUMER_SERVICE=http://localhost/simplesaml/module.php/saml/sp/saml2-acs.php/test-sp \
+	-e SIMPLESAMLPHP_SP_SINGLE_LOGOUT_SERVICE=http://localhost/simplesaml/module.php/saml/sp/saml2-logout.php/test-sp \
+	-d jamedjo/test-saml-idp
+```
+
+2. Add the following configuration settings to $GERRIT_SITE/etc/gerrit.config:
+
+```
+[gerrit]
+	basePath = git
+	canonicalWebUrl = http://localhost:8081/
+[auth]
+	type = HTTP
+	logoutUrl = http://localhost:8080/simplesaml/saml2/idp/SingleLogoutService.php?ReturnTo=http://localhost:8081
+	httpHeader = X-SAML-UserName
+	httpDisplaynameHeader = X-SAML-DisplayName
+	httpEmailHeader = X-SAML-EmailHeader
+	httpExternalIdHeader = X-SAML-ExternalId
+	autoUpdateAccountActiveStatus = true
+[saml]
+	serviceProviderEntityId = gerritSaml
+	keystorePath = /Users/d073103/sites/serviceuserMaster/etc/keystore
+	keystorePassword = pac4j-demo-password
+	privateKeyPassword = pac4j-demo-password
+	metadataPath = http://localhost:8080/simplesaml/saml2/idp/metadata.php
+	userNameAttr = username
+	emailAddressAttr = email
+	computedDisplayName = true
+	firstNameAttr = first_name
+	lastNameAttr = last_name
+[httpd]
+	listenUrl = http://*:8081/
+	filterClass = com.googlesource.gerrit.plugins.saml.SamlWebFilter
+```
+
+3. Generate keystore in `$GERRIT_SITE/etc` local keystore:
+
+```
+keytool -genkeypair -alias pac4j -keypass pac4j-demo-password \
+  -keystore samlKeystore.jks \
+  -storepass pac4j-demo-password -keyalg RSA -keysize 2048 -validity 365
+```
+
+4. Install the saml.jar filter into the `$GERRIT_SITE/lib` directory
+
+5. Start gerrit using: `$GERRIT_SITE/bin/gerrit.sh start`
+
+6. Enter gerrit URL in browser: http://localhost:8081 and hit "Sign In" button
+
+7. SimpleSamlPHP Login Dialog should appear
+
+8. Enter user: "user1" and password: "user1pass" (Note that additional users can
+be added in `config/authsources.php`.)
+
+9. You are redirected to gerrit and the first user/admin User One is created
+in gerrit with the right user name and email address.
+
+12. Congrats, you have Gerrit / SimpleSamlPHP SAML integration up and running.
