Gerrit Saml Plugin is now being developed at https://gerrit.googlesource.com/plugins/saml/
Please report issues by following the instructions at https://www.gerritcodereview.com/issues.html
This plugin allows you to authenticate to Gerrit using a SAML identity provider.
Gerrit looks for 3 attributes (which are configurable) in the AttributeStatement:
- DisplayName: the full name of the user.
- EmailAddress: email address of the user.
- UserName: username (used for ssh).
If any of these attributes is not found in the assertion, their value is taken from the NameId field of the SAML assertion.
- Create a new SAML 2.0 application.
- Set the following parameters:
- Single sign on URL: http://gerrit.site.com/plugins/gerrit-saml-plugin/saml
- Check "Use this for Recipient URL and Destination URL".
- Audience URI (SP Entity Id): http://gerrit.site.com/plugins/gerrit-saml-plugin/saml
- We need to set up the attributes in the assertion to send the right
information. Here is how to do it with Okta:
- Application username: "Okta username prefix"
- Add attribute statement: Name: "DisplayName" with Value "user.displayName"
- Add attribute statement: Name: "EmailAddress" with Value "user.email"
- IMPORTANT: If you are not using Okta, you need to set up an attribute "UserName" with the value of the username (not email, without @). If you do not do so, the name will be taken from the NameId provided by the assertion. This is why in Okta we set the application username to "Okta username prefix".
- Obtain your IdP metadata (either URL or a local XML file)
If you are using Active Directory Federation Services (ADFS), follow the below steps to configure Gerrit. You can then go here for more details on howto make gerrit-saml-plugin work with ADFS.
Download Gerrit SAML plugin for the appropriate version of gerrit:
- gerrit-saml-plugin-2.12-1.jar and put it in $gerrit_site/lib/.
- gerrit-saml-plugin-2.11.5-1.jar and put it in $gerrit_site/lib/.
In $site_path/etc/gerrit.config
file, the [httpd]
section should contain
[httpd]
filterClass = com.thesamet.gerrit.plugins.saml.SamlWebFilter
Please make sure you are using Gerrit 2.11.5 or later.
In $site_path/etc/gerrit.config
file, the [auth]
section should include
the following lines:
[auth]
type = HTTP
logoutUrl = https://mysso.example.com/logout
httpHeader = X-SAML-UserName
httpDisplaynameHeader = X-SAML-DisplayName
httpEmailHeader = X-SAML-EmailHeader
httpExternalIdHeader = X-SAML-ExternalId
The header names are used internally between the SAML plugin and Gerrit to communicate the user's identity. You can use other names (as long as it will not conflict with any other HTTP header Gerrit might expect).
In $gerrit_site/etc
create a local keystore:
keytool -genkeypair -alias pac4j -keypass pac4j-demo-password \
-keystore samlKeystore.jks \
-storepass pac4j-demo-password -keyalg RSA -keysize 2048 -validity 3650
Add a new [saml]
section to $site_path/etc/gerrit.config
:
[saml]
keystorePath = /path/to/samlKeystore.jks
keystorePassword = pac4j-demo-password
privateKeyPassword = pac4j-demo-password
metadataPath = https://mycompany.okta.com/app/hashash/sso/saml/metadata
saml.metadataPath: Location of IdP Metadata from your SAML identity provider.
The value can be a URL, or a local file (prefix with file://
)
saml.keystorePath: Path to the keystore created above. If not absolute,
the path is resolved relative to $site_path
.
saml.privateKeyPassword: Password protecting the private key of the generated
key pair (needs to be the same as the password provided throguh the keypass
flag above.)
saml.keystorePassword: Password that is used to protect the integrity of the
keystore (needs to be the same as the password provided throguh the keystore
flag above.)
saml.maxAuthLifetime: (Optional) Max Authentication Lifetime configuration.
Default is 86400
saml.displayNameAttr: Gerrit will look for an attribute with this name in the assertion to find a display name for the user. If the attribute is not found, the NameId from the SAML assertion is used instead.
Default is DisplayName
saml.emailAddressAttr: Gerrit will look for an attribute with this name in the assertion to find a the email address of the user. If the attribute is not found, the NameId from the SAML assertion is used instead.
Default is EmailAddress
saml.userNameAttr: Gerrit will look for an attribute with this name in the assertion to find a the email address of the user. If the attribute is not found, the NameId from the SAML assertion is used instead.
Default is UserName
