= LDAP UI Installation =

Native LDAP store doesn't come with a GUI. Therefore, as administrators we may have to provide a nice user interface to our users. This UI should have the capability of changing details of users password resets, etc. To do these actions there are lot of open source packages as well as commercialized products.

On this tutorial we will go through two UI setups that will focus on different outputs.

== Apache Directory Studio (For Admins) ==

* Download and install
   The latest version of Apache Directory Studio can be downloaded to your host machine from the Apache Directory Studio Downloads page, at this address : http://directory.apache.org/studio/downloads.html

   Installation steps https://directory.apache.org/studio/users-guide/apache_directory_studio/download_install.html

   Once the installation succeeds open the Apache Directory Studio.

   Creating the ldap connection:
{{{
Go to File --> new --> ldap browser --> ldap connection --> next
}}}

   Enter your deatils:

{{{

   Click `Check Authentication` to make sure your credentials work. For the first time it ask to trust the self signed certificate.

   Select `Always trust this Certificate` and click `OK`

   Then click `Finish`.

* Once connected you can browse through the directory using the LDAP Browser.

* When modifying entries you may use a ldif file or the GUI.

* Using GUI to create an OU:
  - Select '''root location''' for the OU (eg. dc=instXY,dc=ac,dc=lk)
  - Select `New Entry` on '''Right click Menu'''

== Keycloak Server (For End Users) ==

Keycloak is an open source identity and access management solution, we will use keycloak only to provide a friendly self care portal to users allowing services such as password resets.

We will install Keycloak in your idp vm for the lab purpose but it is recommended to install it on a separate server with at least 4GB RAM for production environment.

* Install Dependancies
   * Become the root user by `sudo su`
   * `apt-get install vim default-jdk`
   * Define the constant `JAVA_HOME` inside /etc/environment:
      * `update-alternatives --config java`
        (copy the path without /bin/java)
      * `vim /etc/environment` and include
       * `JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64`
      * `source /etc/environment`
    * `export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64`


* Download Keycloak and extract:
   * 
   {{{
        wget https://downloads.jboss.org/keycloak/4.4.0.Final/keycloak-4.4.0.Final.tar.gz
   }}} 
   {{{
        tar -xvzf keycloak-4.4.0.Final.tar.gz
    }}}

* Go to the executable directory:
   {{{
     cd keycloak-4.3.0.Final/bin/
   }}}
 
* Create Initial Admin User
   {{{
     ./add-user-keycloak.sh -r master -u adminiam -p Iam@2018
    }}}

* Edit listning interface:
   {{{
       vim standalone/configuration/standalone.xml
   }}}
   look for the `interfaces` XML block   
   {{{#!xml
          <interfaces>
                  <interface name="management">
                      <inet-address value="${jboss.bind.address.management:127.0.0.1}"/>
                  </interface>
                  <interface name="public">
                      <inet-address value="${jboss.bind.address:127.0.0.1}"/>
                  </interface>
          </interfaces>
   }}}

  Change IP address `127.0.0.1` to `0.0.0.0` allowing traffic from outside.

* Start the server
{{{
     ./bin/standalone.sh > /var/log/keycloak.pid
}}}
