git clone git://github.com/cloudfoundry/uaa.git
Go to the directory where you cloned the UAA GitHub repository.
To build and run all the components that comprise UAA and the example programs uaa, samples/api, and samples/app, run:
./gradlew run
If successful, the three apps run together on a single instance of Tomcat listening on port 8080, with endpoints /uaa, /app, and /api. Tomcat is a library of Java code used by UAA to create its features. For more information, see the Apache Tomcat website.
 Using local UAA

To access and use a locally deployed UAA server:
Run the UAA server as described in Deploy Locally.
Open another terminal window. From the project base directory, run curl localhost:8080/uaa/info -H "Accept: application/json" to confirm the UAA is running. You can see basic information about the system. For example:
$ curl localhost:8080/uaa/info -H "Accept: application/json"
  "app": {
    "version": "4.19.0"
  "links": {
    "uaa": "http://localhost:8080/uaa",
    "passwd": "/forgot_password",
    "login": "http://localhost:8080/uaa",
    "register": "/create_account"
  "zone_name": "uaa",
  "entityID": "cloudfoundry-saml-login",
  "commit_id": "af93628",
  "idpDefinitions": {},
  "prompts": {
    "username": [
      "text",
      "Email"
    "password": [
      "password",
      "Password"
  "timestamp": "2018-05-25T15:34:31-0700"
To install the Cloud Foundry UAA Command Line Client (UAAC) Ruby gem, run:
gem install cf-uaac
To target the local UAA server endpoint, run:
uaac target http://localhost:8080/uaa
Run uaac token client get CLIENT_NAME -s CLIENT_SECRET to obtain an access token. Replace CLIENT_NAME and CLIENT_SECRET with actual values. For example, when starting up the UAA locally for development, you must have a predefined admin client to use:
uaac token client get admin -s adminsecret
If you run the command without -s CLIENT_SECRET, UAAC shows an interactive prompt where you must create the client secret value. The uaac token client get command requests an access token from the server using the OAuth2 client credentials grant type. For more information about the OAuth2 client credentials, see Client Credentials in the OAuth 2.0 Authorization Framework.

View your UAAC token context. When UAAC obtains a token, the token and other metadata is stored in the ~/.uaac.yml file on your local machine. To view the token you have obtained, run uaac context. For example:
$ uaac context
[0]*[http://localhost:8080/uaa]
[0]*[admin]
  client_id: admin
  access_token: eyJhbGciOiJIUzI1NiIsImtpZCI6ImxlZ2FjeS10b2tlbi1rZXkiLCJ0eXAiOiJKV1QifQ.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.L2cn6HqLQAEyqTrYYkL9Al_8JyfwB330er7DshUb9wg

Copy the access token from this output for the next step.
Run uaac token decode ACCESS-TOKEN-VALUE to view information in the token, which is encoded using the JSON Web Token (JWT) format. Replace ACCESS-TOKEN-VALUE with your access token, copied from the uaac context output. The UAAC displays all the claims inside the token body. For example:

 Deploying UAA to Cloud Foundry

To build the UAA as an app and push it to Cloud Foundry using the Cloud Foundry Command Line Interface (cf CLI):
Clone the UAA GitHub repository by running:

git clone git://github.com/cloudfoundry/uaa.git
Go to the directory where you cloned the UAA GitHub repository.
Build the UAA as a WAR file by running:
./gradlew :cloudfoundry-identity-uaa:war
Run the cf CLI cf push APP-NAME -m 512M -p PATH-TO-WAR-FILE --no-start command to push the app to Cloud Foundry. Replace APP-NAME with a name for your UAA app, and PATH-TO-WAR-FILE with the path to the WAR file you created in the previous step. For example:
cf push MYUAA -m 512M -p uaa/build/libs/cloudfoundry-identity-uaa-1.8.0.war --no-start
Run cf set-env APP-NAME SPRING_PROFILES_ACTIVE default to set the SPRING_PROFILES_ACTIVE environment variable with the value default. Replace APP-NAME with the name of your app that you used in the previous step. For example:
cf set-env MYUAA SPRING_PROFILES_ACTIVE default
Run cf start APP-NAME to start your app. Replace APP-NAME with the name of your app. For example:
cf start MYUAA
 Using remote UAA

You use a UAA server that you pushed as an app to Cloud Foundry in a similar way to one you run locally. You do not need app token encoding because you do not have the client secret.
To access and use a UAA server that you pushed as an app to Cloud Foundry:
Follow the procedure in Deploy UAA to Cloud Foundry.
From the project base directory, run curl -H "Accept: application/json" APP-FQDN/login to query the external login endpoint about the system. Replace APP-FQDN with the fully qualified domain name (FQDN) of your app. For example:
$ curl -H "Accept: application/json" uaa.example.org/login
  "timestamp":"2014-09-15T18:25:04+0000",
  "app":{"version":"1.8.3"},
  "commit_id":"git-metadata-not-found",
  "prompts":{"username":["text","Email"],
      "password":["password","Password"]
Install the UAA Command Line Client (UAAC) Ruby gem by running:
gem install cf-uaac
Target the remote UAA Server endpoint by running:
uaac target APP-FQDN
Where APP-FQDN is the FQDN of your app.

Log in by running:
uaac token get USERNAME PASSWORD
Where:
  
USERNAME is your username.
  
PASSWORD is your password. If you do not specify a username and password, the UAAC prompts you to supply them.
The uaac token client get command authenticates and obtains an access token from the server using the OAuth2 implicit grant, similar to the approach intended for a standalone client like the cf CLI.




    

 Running integration tests

When you run integration tests, it makes sure that the UAA instance is running properly.
To run integrations tests:
./gradlew integrationTest
This command starts a UAA server running in a local Apache Tomcat instance. By default, the service URL is set to http://localhost:8080/uaa.
You can set the environment variable CLOUD_FOUNDRY_CONFIG_PATH to a directory containing a uaa.yml file where you change the URLs used in the tests, and where you can set the UAA server context root.
 Customizing your YAML configuration

A custom YAML configuration gives integration tests access to your UAA instance by sharing
credentials in YAML file.
To create a custom YAML configuration:
Create a uaa.yml file in the following format:
  host: UAA-HOSTNAME
  test:
    username: USERNAME
    password: PASSWORD
    email: EMAIL-ADDRESS
Where:
  
UAA-HOSTNAME is the FQDN of UAA app. For example, uaa.example.org.
  
USERNAME is a valid username. For example, [email protected].

  
PASSWORD is the password for the previous username.
  
EMAIL-ADDRESS is the email address for the previous user. Example: [email protected].
From the uaa/uaa directory, run:
CLOUD_FOUNDRY_CONFIG_PATH=/tmp ./gradlew test
The web app looks for a YAML file in the following locations when it starts, with later entries overriding earlier ones:
  classpath:uaa.yml
  file:${CLOUD_FOUNDRY_CONFIG_PATH}/uaa.yml
  file:${UAA_CONFIG_FILE}
  ${UAA_CONFIG_URL}
 Testing with PostgreSQL or MySQL

The default UAA unit tests, ./gradlew test, use a HyperSQL database.
To use a different database management system:
Create a uaa.yml file containing spring_profiles: default,OTHER-DBMS in the src/main/resources/ directory. Replace OTHER-DBMS with the name of the other database management system to use.
Run the unit tests using your specified database management system instead of a HyperSQL database:
echo "spring_profiles: default,OTHER-DBMS" > src/main/resources/uaa.yml
./gradlew test integrationTest
Where OTHER-DBMS is the name of the database management system you specified in your uaa.yml file.

You can find the database configuration for the common and scim modules at common/src/test/resources/(mysql|postgresql).properties and scim/src/test/resources/(mysql|postgresql).properties.
 UAA projects

The following UAA projects exist:
common: A module containing a JAR with all the business logic. common is used in the web apps.
uaa: The UAA server. uaa provides an authentication service and authorized delegation for back-end services and apps by issuing OAuth2 access tokens.
api: A sample OAuth2 resource service that returns a mock list of deployed apps. api provides resources that other apps might want to access on behalf of the resource owner.
app: A sample user app that uses both api and uaa. app is a web app that requires single sign-on and access to the api service on behalf of users.
scim: The System for Cross-domain Identity Management (SCIM) user management module used by UAA. For more information about SCIM, see Managing Users & Groups with SCIM.
 UAA server

The authentication service, uaa, is a Spring MVC web app. You can deploy it in Tomcat or your container of choice, or run ./gradlew run to run it directly from the uaa directory in the source tree. When run with Gradle, uaa listens on port 8080 and has the URL http://localhost:8080/uaa.
The UAA server supports the APIs defined in the UAA-APIs document which include:
The OAuth2 /authorize and /token endpoints.
A /login_info endpoint to allow querying for required login prompts.
An /introspect endpoint to allow resource servers to obtain information about an access token submitted by an OAuth2 client.
A SCIM user-provisioning endpoint.
OpenID Connect endpoints /userinfo and /check_id to support authentication.
Command-line clients can perform authentication by submitting credentials directly to the /authorize endpoint.
An ImplicitAccessTokenProvider exists in Spring Security OAuth to use if your client is Java.
By default, uaa runs with a context root /uaa.
 Configuration

A uaa.yml file exists in the app. This file provides defaults to the placeholders in the Spring XML.
You can override any occurrences of ${placeholder.name} in the XML by adding it to your uaa.yml file, or by providing a System property with the same name, -D, to your Java virtual machine.
All passwords and client secrets in the configuration files are in plain text, but are inserted into the UAA database encrypted with BCrypt.
 User account data

The default uses an in-memory relational database management system (RDBMS) user store, pre-populated with a single test user marissa with the password koala.
To use PostgreSQL for user data, you must activate the Spring profile postgresql.
You can configure the active profiles in your uaa.yml file using spring_profiles: postgresql,default.
To use PostgreSQL instead of HyperSQL, run:
echo "spring_profiles: postgresql,default" > src/main/resources/uaa.yml
./gradlew run
To bootstrap a microcloud-type environment, you need an admin client. During the bootstrapping process, the database creates a database initializer component that inserts an admin client.
If the default profile is active, the bootstrapping process creates a cf CLI client so that the Gem login works with no additional configuration required. You can override the default settings and add additional clients in the uaa.yml file, as in the following example:
oauth:
  clients:
    admin:
      authorized-grant-types: client_credentials
      scope: read,write,password
      authorities: ROLE_CLIENT,ROLE_ADIN
      id: admin
      secret: adminclientsecret
      resource-ids: clients
You can use the admin client to create additional clients. You must have a client with read/write access to the scim resource to create user accounts. The integration tests handle this automatically by inserting client and user accounts as necessary for the tests.
 Sample apps

Two sample apps are included with UAA: /api and /app.
You can run /api and /app with ./gradlew run from the uaa root directory. All three apps, /uaa, /api, and /app, are simultaneously deployed.
 API sample app

The api sample app is an example resource server. It hosts a service that returns a list of mock apps under /apps.
 App sample app

The app sample app is a user interface app, primarily aimed at browsers, that uses OpenID Connect for authentication and OAuth2 for access grants. app authenticates with the Auth service, then accesses resources in the API service. You can run app with ./gradlew run from the uaa root directory.
The app can operate in multiple different profiles according to the location and presence of the UAA server and the login app. By default, the app looks for a UAA on localhost:8080/uaa, but you can change this by setting the UAA_PROFILE environment variable or System Property.
The app source code, samples/app/src/main/resources, contains multiple properties files pre-configured with different likely locations for those servers. The names of these properties files follow the format app-UAA_PROFILE.properties.
The naming convention for the UAA_PROFILE is:
local: a localhost deployment
vcap: a vcap.me deployment
staging: a staging deployment
Profile names can be hyphenated to indicate multiple contexts. For example, local-vcap can be used when the login server is in a different location than the UAA server.
To see all apps, run:
GET /app/apps
The browser is redirected through a series of authentication and access grant steps.
To see the currently logged-in user details and a selection of attributes from the OpenID provider, run:
GET /app
 Login app

The login app is a user interface for authentication. UAA can also authenticate user accounts, but only if it manages them itself and it only provides a basic UI. You can brand and customize the login app for non-native authentication and for more complicated UI flows, like user registration and password reset.
The log in app is itself an OAuth2 endpoint provider, but delegates those features to
the UAA server. Therefore, configuration for the log in app consists of locating the UAA
through its OAuth2 endpoint URLs and registering the log in app itself as a client of the UAA.
The UAA locations have a login.ymlfile. For example, a local vcap instance:
  url: http://uaa.vcap.example.net
  token:
    url: http://uaa.vcap.example.net/oauth/token
  login:
    url: http://uaa.vcap.example.net/login.do
You can define the environment variable or Java System property login_secret to use a client secret that the app uses when it authenticates itself with UAA. The login app is registered by default in UAA only if there are no active Spring profiles. In UAA, the registration is located in the oauth-clients.xml config file, as in the following example:
id: login
secret: loginsecret
authorized-grant-types: client_credentials
authorities: ROLE_LOGIN
resource-ids: oauth
To authenticate with the login app, run:
GET /login
The sample app presents a form log-in interface for the back end UAA, and an OpenID widget where a user can authenticate using Google or other credentials.
To approve an OAuth2 token grant, run:
GET /oauth/authorize?client_id=app&response_type=code...
This is the standard OAuth2 authorization endpoint. UAA handles client credentials and all other features in the back end, and the login app is used to render the UI.
To obtain the access token, run:
POST /oauth/token
This is the standard OAuth2 authorization endpoint passed through to UAA.
