miniOrange LDAP Gateway

miniOrange LDAP Gateway allows login to publicly/privately hosted sites using credentials stored in Active Directory, OpenLDAP and other LDAP servers. If the LDAP Server is not publicly accessible from your site, this module can be used in conjunction with the miniOrange LDAP Gateway, which is deployed at the DMZ server in the intranet. Another benefit of this module is that multiple LDAP Configurations can be stored for multiple customers of a WordPress based Cloud Service Provider and mapping to the username can be done on the basis of the domain name.

miniOrange gateway is a small piece of software that can reside on a shared machine. It wont need its own machine and our customers generally install it on any server thats already in the DMZ.

Why LDAP Gateway?

LDAP with non public IP - This can be very beneficial if your aim is single sign on but your LDAP exists within your intranet with a non public IP. You can still authenticate your site (which could be anywhere outside your network) and with the help of this two part plugin (plugin + gateway) you can authenticate against your LDAP and achieve single sign on.
Secure calls using HTTPS - All remote calls happen through an encrypted channel.
Setup LDAP configuration once and access from multiple sites - You only need to setup your LDAP configuration once and you can access from multiple sites, thereby achieving ease of use.
Your LDAP stays secure since its behind your firewall.
Cloud based LDAP authentication system - This means that the libraries that are needed to authenticate against your LDAP/AD is not PHP based so it can support a much larger variety of LDAP.

Pre-Requisites

Setup JAVA (JAVA 8/ JDK 1.8)

For Windows Machine use : Click here to Download JAVA 8
For Linux Machine: Download OpenJDK 1.8.

For Debian, Ubuntu, etc. use sudo apt-get install openjdk-8-jre
For Fedora, Oracle Linux, Red Hat Enterprise Linux, etc. use su -c "yum install java-1.8.0-openjdk

Setup Environment Variables

JAVA_HOME: Set this to point to the JDK directory. Eg: C:\Program Files\Java\jdk1.8.0_221
CATALINA_HOME: Set this to point to the Tomcat root directory. Eg: C:\miniorangegateway-1.0.5\

Follow the Step-by-Step Guide given below to Setup miniOrange LDAP Gateway

1. Download and Extract miniOrange Gateway

Click here to Download the latest miniOrange LDAP Gateway Module.
Extract the package to get the Tomcat Embedded LDAP Gateway

2. Configure Port to run miniOrange Gateway (Optional)

To run miniOrange LDAP Gateway on a port other than 8080, Navigate to <miniOrange Gateway Directory>/conf and edit server.xml
Search for " Connector port="8080" protocol="HTTP/1.1" "
Change the port from 8080 to the required port. Eg: 80
Access the gateway from your browser using the url "<hostname:port>/miniorangegateway". Replace "<hostname>" with your hostname or server IP .

3. Setup SSL for LDAP Gateway (Optional)

NOTE: This step is mandatory for Chrome Browser. Chrome will not run the Web-Application on HTTP. For all the other browsers this is optional.

Click here to follow the steps if you have CA certificates.
Follow the below steps if you want dont have CA certificates.
1. Generate Keystore:
  - Navigate to the %JAVA_HOME%\bin directory in the file explorer. Create a certs directory in it.
  - Navigate to the %JAVA_HOME%\bin directory in the command line ( in Administrator mode ) and execute the command:
    keytool -genkey -alias <ALIAS> -keyalg RSA -keystore <JAVA_HOME>\bin\certs\keystore.jks
    
    This creates a keystore in the certs folder created in (a).
2. Configure Connector:
  This is required to configure Tomcat to run on port 443(SSL Port).
  - Navigate to the <Tomcat Directory>\conf and edit the server.xml file.
  - Add a connector element under <Service name="Catalina">. The following configuration needs to be placed in the connector element:
    <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="150" scheme="https"
    secure="true" clientAuth="false" sslProtocol="TLS" keystoreFile="<PATH_TO_KEYSTORE>"
    keystorePass="KEYSTORE_PASSWORD" />
3. Assign Server Name to Tomcat:
  - Edit the %windows%\system32\drivers\etc\hosts file and add the following line:
    127.0.0.1 <newhostname>
  - Navigate to the <Tomcat Directory>\conf and edit the server.xml file.
  - Search for the <Engine name="Catalina" defaultHost="localhost"> and replace localhost with the newhostname of the server.
  - Search for the <Host> element and replace name=localhost with name=<IP Address/DNS> of the server.
  - Restart Tomcat by running startup.bat under <Tomcat Directory>\bin. Navigate to the following address:
    https://<newhostname:port>/miniorangegateway.

4. Starting miniOrange Gateway

Navigate to <miniOrange Gateway Directory>/bin and start the server using the following commands in the terminal:
1. For Windows Machine use : catalina.bat start
2. For Linux Machine: sh catalina.sh start
Access the gateway from your browser using the url "<hostname:port>/miniorangegateway". Replace "<hostname>" with your hostname or server IP .
Eg:localhost:8080/miniorangegateway.

NOTE: If you have configured another port in Step-2, you can use that custom port instead of 8080. Eg. If you configured Tomcat to run on 8081 then the url will be Eg:localhost:8081/miniorangegateway.

5. Log into miniOrange Gateway

On accessing the Gateway Application in your browser. You will be redirected to admin login page.

Enter the login credentials of your miniOrange Cloud Admin Account. [The one you use to login at login.xecurify.com].
After successful login you should be redirected to View LDAP Configurations page.

We support both, scheduled sync as well as One Time Sync. If you want to start the sync immediately or want to use One-Time Sync then configure the time which has already passed in the Start Time(hh:mm) field.

Eg. If the server time is 13:00 then anytime before 13:00 should initiate immediate sync.

Restart the Tomcat Server.

12. Steps to deploy tomcat as Windows/Linux service

For Windows
For Linux

Install Tomcat as a Windows Service using a Windows Installer.
Navigate to the Tomcat Package that was provided by us and copy over the miniorangegateway folder under the webapps directory to the newly installed Tomcat as a service webapps folder.

Now you can navigate to the windows services panel and start the Tomcat service.

Create and open the unit file by running this command:

sudo vi /etc/systemd/system/tomcat.service

Paste in the following script. You may also want to modify the memory allocation settings that are specified in CATALINA_OPTS:

# Systemd unit file for tomcat
    [Unit]
    Description=Apache Tomcat Web Application Container
    After=syslog.target network.target

    [Service]
    Type=forking

    Environment=JAVA_HOME= <Location of your JRE> Eg: /usr/lib/jvm/jre
    Environment=CATALINA_PID=<Location of your PID file> Eg:/opt/miniorangegateway-1.x.x/temp/tomcat.pid
    Environment=CATALINA_HOME=<Location of your miniOrange Tomcat Directory> Eg: /opt/miniorangegateway-1.x.x
    Environment=CATALINA_BASE=<Location of your miniOrange Tomcat Directory> Eg: /opt/miniorangegateway-1.x.x
    Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'
    Environment='JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom'

    ExecStart=/opt/tomcat/bin/startup.sh
    ExecStop=/bin/kill -15 $MAINPID

    User=tomcat
    Group=tomcat
    UMask=0007
    RestartSec=10
    Restart=always

    [Install]
    WantedBy=multi-user.target

Save and exit. This script tells the server to run the Tomcat service as the tomcat user, with the settings specified.
Now reload Systemd to load the Tomcat unit file:

sudo systemctl daemon-reload

Now you can start the Tomcat service with this systemctl command:

sudo systemctl start tomcat

Check that the service successfully started by typing:

sudo systemctl status tomcat

If you want to enable the Tomcat service, so it starts on server boot, run this command:

sudo systemctl enable tomcat
