Merge branch 'stable-2.16' into stable-3.0 * stable-2.16: Create HTTP session only for login requests Change-Id: I432b5917224f4e56c6167384ba069d7976718aee
This filter allows you to authenticate to Gerrit using a SAML identity provider.
Gerrit looks for 3 attributes (which are configurable) in the AttributeStatement:
If any of these attributes is not found in the assertion, their value is taken from the NameId field of the SAML assertion.
Download Gerrit SAML plugin for the appropriate version of gerrit from the Gerrit-CI into $gerrit_site/lib/.
This authentication filter is built with Bazel.
Clone or link this filter to the plugins directory of Gerrit's source tree. Put the external dependency Bazel build file into the Gerrit /plugins directory, replacing the existing empty one.
cd gerrit/plugins rm external_plugin_deps.bzl ln -s @PLUGIN@/external_plugin_deps.bzl .
Then issue
bazel build plugins/@PLUGIN@
The output is created in
bazel-bin/plugins/@PLUGIN@/@PLUGIN@.jar
The @PLUGIN@.jar should be deployed to gerrit_site/lib
directory:
cp bazel-bin/plugins/@PLUGIN@/@PLUGIN@.jar `$gerrit_site/lib`
NOTE: Even though the project is built as a Gerrit plugin, it must be loaded as a Servlet filter by Gerrit and thus needs to be located with the libraries and cannot be dynamically loaded like other plugins.
This project can be imported into the Eclipse IDE. Add the plugin name to the CUSTOM_PLUGINS
set in Gerrit core in tools/bzl/plugins.bzl
, and execute:
./tools/eclipse/project.py
How to build the Gerrit Plugin API is described in the Gerrit documentation.
In $site_path/etc/gerrit.config
file, the [httpd]
section should contain
[httpd] filterClass = com.googlesource.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 (secs) 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.computedDisplayName: Set to compute display name attribute from first and last names.
Default is false.
saml.firstNameAttr: Gerrit will look for an attribute with this name in the assertion to find the first name of the user. Only used, when computedDisplayName
is set to true. If the attribute is not found, the NameId from the SAML assertion is used instead.
Default is FirstName
saml.lastNameAttr: Gerrit will look for an attribute with this name in the assertion to find the last name of the user. Only used, when computedDisplayName
is set to true. If the attribute is not found, the NameId from the SAML assertion is used instead.
Default is LastName
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
saml.serviceProviderEntityId: SAML service provider entity id.
Default is not set.
saml.identityProviderEntityId: SAML identity provider entity id. When present a IDPSSODescriptor
is expected in the SAML metadata document. When absent a saml service provider with its SPSSODescriptor
is assumed. This value takes precedence over the value in saml.serviceProviderEntityId.
Default is not set.
saml.useNameQualifier: By SAML specification, the authentication request must not contain a NameQualifier, if the SP entity is in the format nameid-format:entity. However, some IdP require that information to be present. You can force a NameQualifier in the request with the useNameQualifier parameter. For ADFS 3.0 support, set this to false
.
Default is true.
