h2. Introduction

By default, Petals View is configured to works with an embedded User Management system that allows to manage application users directly from the Petals View GUI. So, if you want to delegate authentication to a REALM system or LDAP system or CAS system, you have to do configurations according to your needs.

{warning}
Be careful, if you enable REALM, LDAP or CAS authentication, the User Management system embedded in Petals View will be completely disabled. So the User Management section in the Petals View GUI will become useless. Authentication will be managed by the REALM mode, LDAP server or CAS server and user roles management will be externalised {warning}

Go to the Petals View web application directory in your application server web app repository. We'll call it PETALSVIEW_ROOT in this page.

h2. Available roles

To use an external authentication, you need to add some specific roles to the users to customize their Petals View access rights. Here is a list of available roles:

*ROLE_FLOWREFMANAGER*: allows the user to access to the Flow Referential management section.

*ROLE_FLOWMANAGER*: allows the user to access to the Flow instances management section.

{warning}
You must add the role "*ROLE_AUTH*" to all users so that they're authorized to access the Petals View web application.
{warning}

h2. Authentication with REALM

h3. web.xml configuration

You must edit the web.xml (in PETALSVIEW_ROOT/WEB-INF repository) file and change comments. Comment the "classical authentication" section and the line "/WEB-INF/spring/petals-view-security-classical.xml". Uncomment the "realm authentication" section.

An exemple *web.xml* is provided here:

You must configure your server to add realm security.

h3. Tomcat configuration

For Tomcat, you must edit context.xml (in PETALSVIEW_ROOT/META-INF/ repository). Uncomment "JAAS implementation" or "JNDI implementation for ldap" or "JDBC implementation" and change the configuration according to your need.

An exemple *context.xml* is provided here with JAAS implementation:

{cloak:id=code2}
{code:lang=xml}

h3. Configure CAS properties

...

Now you have to configure CAS properties in the *PETALSVIEW_ROOT{*}*/WEB-INF/Classes/*{*}petalsview.properties* file. Here is a sample configuration for a CAS server available at "https://localhost:8443/cas" and a Petals View instance available at "http://localhost:9080/petals-view-ui":

{code}
## CAS properties
cas.server.url = https://localhost:8443/cas
cas.logout.path = /logout
cas.login.path = /login
webapp.url = http://localhost:9080/petals-view-ui
{code}

*cas.server.url* : your CAS server URL.

*cas.logout.path* : the path to the CAS server logout page. In the above example, the full URL to the logout page is: [https://localhost:8443/cas/logout].

{color:#333333}{*}cas.login.path{*}{color} {color:#333333}: the path to the CAS server login page. In the above example, the full URL to the login page is : {color}{color:#000000}https:{color}{color:#000000}//localhost:8443/cas/login.{color}

{color:#000000}{*}webapp.url{*}{color} {color:#000000}:{color} the URL to your Petals View webapp. This URL must be accessible from the CAS server as it will redirect to this URL after authentication.

h3. *petals-view-security-cas.xml* configuration

By default, Petals View CAS authentication manager is plugged with a user rights manager that provides all rights to all authenticated users. If you would like to customize this behavior, you need to configure an other user rights manager. This could be done in the *PETALSVIEW_ROOT{*}*/WEB-INF/spring/petals-view-security-cas.xml* file. You have to change the bean called "myUserDetailsService" to point to your custom user detail service. Here is the code snippet showing the default user details service configuration provided by Petals View.

{code:lang=xml}
<bean id="myUserDetailsService"
class="com.ebmwebsourcing.petalsview.util.FullAccessRightsUserDetailsService">
<property name="rolesResource">
<value>${role.list.file.url}</value>
</property>
</bean>
{code}

Spring provides a lot of user details service implementations for different types of user rights repositories like LDAP, JDBC, etc. For more information about user details services see [http://static.springsource.org/spring-security/site/docs/3.0.x/reference/technical-overview.html#d4e758].

Your CAS server is also based on a Spring framework, so if you want to use the same user details service as the one configured in your CAS server, you could find it in the */WEB-INF/deployerConfigContext.xml* avalaible in the CAS server webapp directory.

{warning}Be careful, the Spring framework version used in CAS server is 2.5 which is different from the one used in Petals View. Some packages have changed, but you could easily retrieve equivalent classes.{warning}

Here is a simple In Memory user details service for Spring 2.5.x:

{code:lang=xml}<bean id="userDetailsService" class="org.springframework.security.userdetails.memory.InMemoryDaoImpl">
<property name="userMap">
<value>
admin=dummy,ROLE_AUTH,ROLE_FLOWMANAGER,ROLE_FLOWREFMANAGER,ROLE_USERMANAGER
refmanager=dummy,ROLE_AUTH,ROLE_FLOWREFMANAGER
fluxmanager=dummy,ROLE_AUTH,ROLE_FLOWMANAGER
</value>
</property>
</bean> {code}

Here is the same user details service, but for Spring 3.0.x:

{code:lang=xml}<bean id="userDetailsService" class="org.springframework.security.core.userdetails.memory.InMemoryDaoImpl">
<property name="userMap">
<value>
admin=dummy,ROLE_AUTH,ROLE_FLOWMANAGER,ROLE_FLOWREFMANAGER,ROLE_USERMANAGER
refmanager=dummy,ROLE_AUTH,ROLE_FLOWREFMANAGER
fluxmanager=dummy,ROLE_AUTH,ROLE_FLOWMANAGER
</value>
</property>
</bean>
{code}

{info}The password is set to "dummy" for the three user defined because it isn't used (password based authentication is done by the CAS server). Only role list for each users is useful.

In Memory user details service isn't for production purposes. Use LDAP, JDBC or something else to connect to your user repository in production environment.{info}
