grails-tomcat-realm

test grails application with a tomcat realm

Assumptions:

CentOS 6.2

[chuck@centos-62-64-vm3 grails-tomcat-realm]$ cat /etc/redhat-release 
CentOS release 6.2 (Final)

Prereqisites:

Tomcat v7

CATALINA_HOME=/home/chuck/workspace/apache-tomcat-7.0.29
CATALINA_BASE=/home/chuck/workspace/apache-tomcat-7.0.29

Tomcat Configured with (see https://github.com/connaryscott/JaasDev):

JAAS Login Module: $CATALINA_HOME/lib/JaasTutorial.jar
JAAS Configuration: $CATALINA_BASE/conf/sample_jaas.config 
helloworld context configuration:  $CATALINA_BASE/conf/Catalina/localhost/helloworld.xml 

CATALINA_OPTS=-Djava.security.auth.login.config=${CATALINA_BASE}/conf/sample_jaas.config

OpenLDAP Setup (see https://github.com/connaryscott/JaasDev)

Java/JVM 1.6

JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64

Grails v2.0.4

GRAILS_HOME=/home/chuck/workspace/grails-2.0.4
[chuck@centos-62-64-vm3 grails-tomcat-realm]$ which grails
~/workspace/grails-2.0.4/bin/grails

Create a trivial Hello World Grails App

Per hello world instructions, http://grails.org/doc/2.0.x/guide/gettingStarted.html#aHelloWorldExample, create a hello world app

[chuck@centos-62-64-vm3 grails-tomcat-realm]$ grails create-app helloworld
| Created Grails Application at /home/chuck/workspace/grails-tomcat-realm/helloworld
[chuck@centos-62-64-vm3 grails-tomcat-realm]$ cd helloworld/
[chuck@centos-62-64-vm3 helloworld]$ grails create-controller hello
| Compiling 38 source files

| Created file grails-app/controllers/helloworld/HelloController.groovy
| Created file grails-app/views/hello
| Created file test/unit/helloworld/HelloControllerTests.groovy

[chuck@centos-62-64-vm3 helloworld]$ vi grails-app/controllers/helloworld/HelloController.groovy 

[chuck@centos-62-64-vm3 helloworld]$ cat grails-app/controllers/helloworld/HelloController.groovy 
package helloworld

class HelloController {

    def index() { 
        render "Hello World!"
    }
}

Verify Hello World App Runs

[chuck@centos-62-64-vm3 helloworld]$ grails run-app
| Compiling 38 source files

| Server running. Browse to http://localhost:8080/helloworld

Install dreaded Spring Security

[chuck@centos-62-64-vm3 helloworld]$ vi grails-app/conf/BuildConfig.groovy

And add the spring-security-core plugin

    plugins {
        runtime ":hibernate:$grailsVersion"
        runtime ":jquery:1.7.1"
        runtime ":resources:1.1.6"

        compile ":spring-security-core:1.2.7.1"

Compile and trigger new dependency downloads

[chuck@centos-62-64-vm3 helloworld]$ vi grails-app/conf/BuildConfig.groovy

Resolving plugin JAR dependencies

*******************************************************
* You've installed the Spring Security Core plugin.   *
*                                                     *
* Next run the "s2-quickstart" script to initialize   *
* Spring Security and create your domain classes.     *
*                                                     *
*******************************************************

| Compiling 9 source files.

Run the s2-quickstart script with User/Role domain classes

[chuck@centos-62-64-vm3 helloworld]$ grails s2-quickstart helloworld User Role

| 
*******************************************************
* Created domain classes, controllers, and GSPs. Your *
* grails-app/conf/Config.groovy has been updated with *
* the class names of the configured domain classes;   *
* please verify that the values are correct.          *
*******************************************************

[chuck@centos-62-64-vm3 helloworld]$ find grails-app/domain 
grails-app/domain
grails-app/domain/helloworld
grails-app/domain/helloworld/Role.groovy
grails-app/domain/helloworld/UserRole.groovy
grails-app/domain/helloworld/User.groovy

Configure Hello World Grails Templates

[chuck@centos-62-64-vm3 helloworld]$ grails install-templates
| Templates installed successfully

modify the source web.xml for the ROLE_YANA_USER role

[chuck@centos-62-64-vm3 helloworld]$ vi src/templates/war/web.xml 

<login-config>
    <auth-method>BASIC</auth-method>
    <realm-name>Example Basic Authentication</realm-name>
</login-config>
<security-constraint>
        <web-resource-collection>
                <web-resource-name>web</web-resource-name>
                <url-pattern>/*</url-pattern>
        </web-resource-collection>
        <auth-constraint>
                <role-name>*</role-name>
       </auth-constraint>
</security-constraint>
<security-role>
        <role-name>ROLE_YANA_USER</role-name>
</security-role>

Generate the Hello World war and deploy to Tomcat

[chuck@centos-62-64-vm3 helloworld]$ grails war
| Done creating WAR target/helloworld-0.1.war

[chuck@centos-62-64-vm3 helloworld]$ rm -rf ${CATALINA_BASE}/webapps/helloworld*
[chuck@centos-62-64-vm3 helloworld]$ cp target/helloworld-0.1.war ${CATALINA_BASE}/webapps/helloworld.war
[chuck@centos-62-64-vm3 helloworld]$ $CATALINA_BASE/bin/startup.sh
Using CATALINA_BASE:   /home/chuck/workspace/apache-tomcat-7.0.29
Using CATALINA_HOME:   /home/chuck/workspace/apache-tomcat-7.0.29
Using CATALINA_TMPDIR: /home/chuck/workspace/apache-tomcat-7.0.29/temp
Using JRE_HOME:        /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64
Using CLASSPATH:       /home/chuck/workspace/apache-tomcat-7.0.29/bin/bootstrap.jar:/home/chuck/workspace/apache-tomcat-7.0.29/bin/tomcat-juli.jar

When connecting to http://:8080/helloworld/ with the following credendials:

username:  rfirefly
password:  Gr0uch0M@rx

Which shows that we authenticated in the catalina.out
