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: 

Connection Name: LDAP Server
Hostname: idp.instXY.ac.lk
port: 389
Encrypted Method: Use STARTTLS
Provider: Apache Directory LDAP Client API

Next 

Authentication Method: Simple Authentication
Bind Dn: cn=admin,dc=instXY,dc=ac,dc=lk
Bind Password:

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.

  • To connect, double click the connection just created from Connections list.
  • 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
    • Then Create entry from Scratch --> Next
    • Select OrganizationalUnit and click Add and Next
    • Type OU as the RDN and the desired value in-front of it, then click Next and Finish
  • Adding a User Group
    • Select root location for the OU (eg. ou=Group,dc=instXY,dc=ac,dc=lk)
    • Select New Entry on Right click Menu
    • Then Create entry from Scratch --> Next
    • Select groupofNames and click Add and Next
    • Type CN as the RDN and the desired value in-front of it and then click Next
    • You will prompt with a user add window as DN Editor. Select a user from browser and click OK
  • Adding a new User
    • Select root location for the OU (eg. ou=People,dc=instXY,dc=ac,dc=lk)
    • Select New Entry on Right click Menu
    • Then Create entry from Scratch --> Next
    • Select inetOrgPerson and click Add
    • Select eduPerson and click Add and Next
    • Type uid as the RDN and the desired username value in-front of it and then Next
    • Enter desired values for cn (First Name) and sn (last Name)
    • Enter new attribute from right click menu as userPassword and click finish. when it asks, enter the new users password and select Plaintext as the hash method and click OK
    • You may add any other attribute as well.
    • Then click finish

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 and save & exit.
      • Then make that environment active by source /etc/environment
    • Also we need to export the variable using 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-4.4.0.Final/bin/

  • Create Initial Admin User 
      ./add-user-keycloak.sh -r master -u adminiam -p Iam@2018
  • Edit listning interface: 
       cd ..
    vim standalone/configuration/standalone.xml

look for the interfaces XML block 

       <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 &
  • Log in to the master admin console. This will provide full privileged access to the system.
  • Create your own realm (domain)
    • From the Master drop-down menu, click Add Realm.
    • Put instXY as the Name and Add

From here onwards, make sure you select instXY from the master menu when doing changes.

  • Customizing Realm
    • Go to your "Realm Settings"
    • On General tab
      • Enter display name as Institute XY
      • Enter HTML display name as <span><img src="URL-TO-YOUR-LOGO"></span> and SAVE
    • On Login tab
      • Switch on Forgot password
      • Switch off Login with email and SAVE
  • Connect your ldap instance:
    • Go to User Federation and select ldap from add provider drop down menu.
      • Mark Edit Mode as WRITEABLE
      • Sync Registrations as ON
      • Vender as Other
      • User Object Classes as inetOrgPerson, organizationalPerson, eduPerson, extensibleObject
      • Connection URL as ldap://idp.instXY.ac.lk:389
      • Users DN as ou=people,dc=instXY,dc=ac,dc=lk
      • Authentication type as simple
      • BIND DN as cn=admin,dc=instXY,dc=ac,dc=lk
      • Bind Credential as iam@2018
      • Search Scope as subtree
      • Periodic Full Sync as ON
      • Periodic Changed Users Sync as ON
      • Save
      For the first time you will need to click Synchronize All Users
  • Map User Attributes

You have to map user attributes that are essential in password resetting. When a user clicks forgot password link it will send a reset link to a working email. Keep in mind that the attribute mail should be the key attribute for mapping the ldap user for various outside services. Therefore it should be something in the format user@instXY.ac.lk and it should not be allowed to be changed by the users. Because of this, we will use ldap attribute email to fill in the alternate email of the user which is used to send the reset requests.

To do this you need to edit the ldap email mapper from the settings.

Go to User Federation --> ldap --> Mappers and select email

Change the value of LDAP Attribute to email and Save.

On your production servers you need to configure your email server settings on Realm Settings --> Email

Ask Users to login to ​https://idp.instXY.ac.lk:8443/auth/realms/instXY/account change there user profile and details (Change instXY in the url as per your realm name)

  • Usage of OTP.

Users can utilize the function OTP from their profile page. They may use any OTP software such as Google Authenticator, Authy, etc. This will add additional security to the password reset process.

  • Customize User Profile page to change ldap attribute values.

By default users are only allowed to change Email, First Name and Last Name. But if you want to provide them access to change their any other details, you need to customize the template from the back end.

Steps in Adding attribute mobile to be edited by users:

  • First include the custom attribute by accessing User Federation --> ldap --> Mappers --> Add
    • Name: mobile
    • Mapper Type: user-attribute-ldap-mapper
    • User Model Attribute: mobile
    • LDAP Attribute: mobile
    • Save
    • Do to Settings tab and click Synchronize All Users
  • Then you should see mobile values under attributes tab of the User's details page.
  • Next we have to customize the User Profile. For that you must log back to your Keycloak server (in this case IDP) and become root.
  • Create a custom theme as instXY 
        cd KEYCLOAK-DIRECTORY

       cp -r themes/keycloak themes/instXY
   cp themes/base/account/account.ftl themes/instXY/account/account.ftl
    The first cp command will create an exact copy of default keycloak theme as instXY and the second cp will create a copy of user profile page in to our theme.
  • Next edit the themes/instXY/account/account.ftl and include following just above the form group <div class="form-group"> <div id="kc-form-buttons" class="col-md-offset-2 col-md-10 submit"> 
          <div class="form-group">
         <div class="col-sm-2 col-md-2">
             <label for="user.attributes.mobile" class="control-label">Mobile number</label>
         </div>

         <div class="col-sm-10 col-md-10">
             <input type="text" class="form-control" id="user.attributes.mobile" name="user.attributes.mobile" value="${(account.attributes.mobile!'')}"/>
         </div>
      </div>
  • Then we have to restart the keycloak service 
        bin/jboss-cli.sh --connect command=:shutdown
    bin/standalone.sh &
  • Next log back to the admin console of keycloak and traverse to Realm Settings --> Themes and change the value of Account Theme to instXY
  • Now you may log in to user profile ​https://idp.instXY.ac.lk:8443/auth/realms/instXY/account and check whether the settings have applied, remember to use a private window as you needs to be authenticated as an ldapuser

For further customization you may consult keycloak official guides from ​https://www.keycloak.org/docs/latest/server_development/index.html#_themes
