Hosting Authentication Endpoint on a Different Server

The authenticationendpoint contains the authentication URLs used in authentication flow. You can either host the authenticationendpoint webapp on the WSO2 Identity Server, or choose to host it on a separate server. You may want to host it separately for the purpose of having custom theming and branding. This section describes how you can host the authentication endpoint on a different server outside the WSO2 Identity Server (e.g., in a different Tomcat Server).

Moving the authenticationendpoint from WSO2IS and hosting it on a separate web server

Before you begin:

First, get a copy of <IS_HOME>/repository/deployment/server/webapps/authenticationendpoin.war to <WebApp_HOME>/ and unzip it. Make sure to get the authenticationendpoin.war after the WUM update and NOT the extracted authenticationendpoint in <IS_HOME>/repository/deployment/server/webapps/

Copy the following .jar files from the <IS_HOME>/repository/components/plugins/ directory to the <WebApp_HOME>/authenticationendpoint/WEB-INF/lib directory.

```
org.wso2.carbon.base_4.4.11.jar
```
```
org.wso2.carbon.identity.base_5.7.5.jar
```
```
org.wso2.carbon.ui_4.4.11.jar
```

org.wso2.carbon.identity.application.authentication.endpoint.util_5.7.5.jar

```
org.wso2.carbon.identity.core_5.7.5.jar
```
```
httpcore_4.3.3.wso2v1.jar
```

org.wso2.carbon.identity.user.registration.stub_5.7.5.jar

```
axis2_1.6.1.wso2v20.jar
```
```
org.wso2.carbon.user.api_4.4.11.jar
```
```
opensaml_2.6.4.wso2v3.jar
```
```
org.wso2.carbon.utils_4.4.11.jar
```
```
jettison_1.3.4.wso2v1.jar
```
```
org.wso2.carbon.user.core_4.4.11.jar
```

Copy the following .jar files from the <IS_HOME>/lib/runtimes/cxf/ directory to the <WebApp_HOME>/authenticationendpoint/WEB-INF/lib directory.
- javax.ws.rs-api-2.0-m10.jar
- cxf-bundle-2.7.16.wso2v1.jar
- neethi-3.0.3.jar
- wsdl4j-1.6.3.jar

Uncomment following section in <WebApp_HOME>/authenticationendpoint/WEB-INF/web.xml and point to identity server URLs.

...   
<context-param>
       <param-name>IdentityManagementEndpointContextURL</param-name>
<param-value>https://$WEB_SERVER_HOST:$WEB_SERVER_PORT/accountrecoveryendpoint</param-value>
   </context-param>
    <context-param>
       <param-name>AccountRecoveryRESTEndpointURL</param-name>
     <param-value>https://localhost:9443/t/tenant-domain/api/identity/user/v0.9/</param-value>
   </context-param>
...
    <context-param>
        <param-name>IdentityServerEndpointContextURL</param-name>
        <param-value>https://localhost:9443</param-value>
    </context-param>
...

Change the following configuration in <IS_HOME>/repository/conf/identity/application-authentication.xml file

<AuthenticationEndpointURL>/authenticationendpoint/login.do</AuthenticationEndpointURL>
<AuthenticationEndpointRetryURL>/authenticationendpoint/retry.do</AuthenticationEndpointRetryURL>
<AuthenticationEndpointMissingClaimsURL>/authenticationendpoint/claims.do</AuthenticationEndpointMissingClaimsURL>

as follows:

<AuthenticationEndpointURL>https://$WEB_SERVER_HOST:$WEB_SERVER_PORT/authenticationendpoint/login.do</AuthenticationEndpointURL>
<AuthenticationEndpointRetryURL>https://$WEB_SERVER_HOST:$WEB_SERVER_PORT/authenticationendpoint/retry.do</AuthenticationEndpointRetryURL>
<AuthenticationEndpointMissingClaimsURL>https://$WEB_SERVER_HOST:$WEB_SERVER_PORT/authenticationendpoint/claims.do</AuthenticationEndpointMissingClaimsURL>

You will need to add AuthenticationEndpointMissingClaimsURL configuration, as it is not already available in this configuration file.

Change the following configuration in <IS_HOME>/repository/conf/identity/identity.xml file to point to the authentication endpoint hosted outside the wso2 server.

Import the public certificate of the identity server to the javaca certs (or web-serverstruststore) of the JVM that the authenticationendpoint is running.

keytool -export -keystore $IS_HOME/repository/resources/security/wso2carbon.jks -alias wso2carbon -file wso2carbon.cer

keytool -import -alias wso2carbon -keystore  $WEB_APP_TRUSTSTORE -file wso2carbon.cer

Import the public certificate of the Web_server’s keystore to the Identity Server truststore.

keytool -export -keystore $WEB_APP_KEYSTORE -alias wso2carbon -file webserver.cer

keytool -import -alias <alias> -keystore  $IS_HOME/repository/resources/security/client-trustore.jks -file webserver.cer

Moving the accountrecoveryendpoint from WSO2IS and hosting it on a separate web server

This is an additional improvement which enables hosting accountrecoveryendpoint.war also on a separate web server.

Before you begin:

Get a copy of <IS_HOME>/repository/deployment/server/webapps/accountrecoveryendpoint.war to <WebApp_HOME>/ and unzip it. Make sure to get the accountrecoveryendpoint.war after the WUM update and not the extracted accountrecoveryendpoint in <IS_HOME>/repository/deployment/server/webapps/

In <WebApp_HOME>/accountrecoveryendpoint/WEB-INF/classes/RecoveryEndpointConfig.propertiesfile, uncomment and change it to identity server.
```
identity.server.service.contextURL=https://localhost:9443/services/
```

Uncomment and change the user portal reference in <WebApp_HOME>/accountrecoveryendpoint/WEB-INF/web.xml

<context-param>
        <param-name>UserPortalUrl</param-name>
        <param-value>https://localhost:9443/dashboard/index.jag</param-value>
</context-param>

Export the following paths.

export WEB_APP_HOME=/Users/userfoo/apache-tomcat-7.0.81/webapps
export IS_HOME=/Users/userfoo/wso2is-5.6.0
export WEB_APP_LIB=${WEB_APP_HOME}/accountrecoveryendpoint/WEB-INF/lib/

Note: WEB_APP_HOME and IS_HOME paths are given as examples. You may have to change them according to your environment.

Copy the following dependencies to <WebApp_HOME>/authenticationendpoint/WEB-INF/lib

cp $IS_HOME/repository/components/plugins/org.wso2.carbon.base_4.4.11.jar $WEB_APP_LIB
cp $IS_HOME/repository/components/plugins/org.wso2.carbon.identity.base_5.7.5.jar $WEB_APP_LIB

Note: Make sure the WebApp container server (of endpoint apps) is running with SSL enabled.

e.g., if tomcat enabled the https connector, add the following to catalina.sh.

JAVA_OPTS="$JAVA_OPTS -Djavax.net.ssl.keyStore=$WEB_SERVER_KEYSTORE -Djavax.net.ssl.keyStorePassword=$password"
JAVA_OPTS="$JAVA_OPTS -Djavax.net.ssl.trustStore=$WEBSERVER_TRUSTORE -Djavax.net.ssl.trustStorePassword=$password"

Running the sample

Download and install WSO2 IS and apache-tomcat into your local machine. Let’s consider IS installation as <IS_HOME> and tomcat installation as <TOMCAT_HOME>
Get the sample setup scripts from the following location: https://github.com/ayshsandu/samples/tree/master/is_samples/is_5.6.0/hosting-endpoints.
Open <TOMCAT_HOME>/conf/server.xml file and enable the https connector on 8443 port.
```
<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
          maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
          clientAuth="want" sslProtocol="TLS"
          sslEnabledProtocols="TLSv1,TLSv1.1,TLSv1.2"      keystoreFile="$IS_HOME/repository/resources/security/wso2carbon.jks"
keystorePass="wso2carbon" truststoreFile="$IS_HOME/repository/resources/security/client-truststore.jks" truststorePass="wso2carbon"/>
```
For this sample, we configured the same keystore and truststore in WSO2IS as the keystore and truststore in tomcat. In an actual environment, you may create a new keystore and truststore for tomcat and point to it. When using separate keystores and truststores, you need to import tomcat keystore’s public cert in to:
< IS_HOME>/repository/resources/security/client-truststore.jks and, public cert of < IS_HOME>/repository/resources/security/wso2carbon.jks into tomcat’s truststore.

Open <TOMCAT_HOME>/bin/catalina.sh and add following JAVA_OPTS.

JAVA_OPTS="$JAVA_OPTS --Djavax.net.ssl.keyStore=$IS_HOME/repository/resources/security/wso2carbon.jks -Djavax.net.ssl.keyStorePassword=wso2carbon"
JAVA_OPTS="$JAVA_OPTS -Djavax.net.ssl.trustStore=$IS_HOME/repository/resources/security/client-truststore.jks -Djavax.net.ssl.trustStorePassword=wso2carbon"

Run setup-authentication.sh obtained from step 2 and follow the instructions.
Once the script is complete, then the authentication endpoint is set up in the given <TOMCAT_HOME>/webapps location.

Uncomment following section in <TOMCAT_HOME>/webapps/authenticationendpoint/WEB-INF/web.xml file and point to identity server URLs.

Start both Identity Server and tomcat and access https://localhost:9443/dashboard. Now you can see that the authentication is redirected to: https://localhost:8443/authenticationendpoint/login.do
Now let’s take out account recovery endpoint into the external Tomcat server as well.
Run setup-accountrecovery.sh obtained from step 2 and follow the instructions.

Change the following section in <TOMCAT_HOME>/webapps/authenticationendpoint/WEB-INF/web.xml file and point to IdentityManagementEndpointContextURL into tomcat URL.

…
