inWebo LDAP Proxy v1.2.0

The inWebo LDAP proxy allows you to add strong authentication via the InWebo service.

Its role is to transmit the LDAP requests to the LDAP server. When a Bind request from the LDAP server is returned successfully, a PUSH request is sent to the InWebo server. The user is then prompted to authenticate (PIN code, fingerprint, etc) on his previously registered device.

If the PIN is correct, the LDAP proxy finalizes the Bind request and the user is authenticated.

Prerequisite

Infrastructure

The machine hosting the proxy must have:

Access to the LDAP server that will need to be synchronized with the inWebo proxy
Internet access to reach the InWebo API

Software

Windows or Linux

64-bit environment
JAVA 8 64 bits for the version without JRE

For LDAPS / SSL

.P12 certificate and passphrase from local Authority

Installation

For Linux operating systems

Retrieve the Linux version: proxy-ldap-packaging-X.Y.Z-linux64.tar.gz

Unpack the archive
Create the config/config.properties file from the config_to_be_completed.properties file
Complete the config/config.properties file (see below)
Start the proxy

Version using the JRE installed on the system

BASH

inWebo proxy service start and stop

If your LDAP proxy listens for services numbered under 1024, you must start the proxy service with a root / administrator user.

Lauching the Proxy service in background mode

BASH

sudo ./run_standalone.sh &

BASH

sudo ./stop.sh

Edit bin/iw_ldap_proxy by replacing
1. @iw_ldap_proxy_installation_dir@ by the path of the installation directory
2. @iw_ldap_proxy_user@ by the user who runs the program
Installation

Tests and troubleshooting inWebo LDAP Proxy Configuration

2 additional commands are included for Linux and Windows:

Testing Push and inWebo certificate in command line

VB

run_standalone -doPush <login_inWebo>

Allows you to test directly the push Authentication of an inWebo login for your service and see if you are correctly notified with the current inWebo configuration (serviceID, inWebo Certificate, Passphrase)

VB

run_standalone -validateConfiguration <DN>(ex: run_standalone -validateConfiguration CN=Administrator,CN=Users,DC=Domain,DC=test)

will allow you to test if the LDAP configuration and the Bind command is successful

How to configure your LDAP authentication

This application is used to transfer LDAP search/authentication request to the real authentication LDAP and if accepted it will send an additional authentication request in HTTPS to the inWebo platform.
This additional request is based on the user attribute defined in the proxyLDAP configuration and retrieved from the user profile (uid, cn, samAccount, userPrincipleName)

Creating the LDAP credentials (DN) for Binding requests on LDAP server

To bind the LDAPproxy to the target LDAP server it is recommended to indicate or even create a whitelisted DN/Account used to search the LDAP.
ex: CN=ReadOnly,CN=Users,DC=domain,DC=test

This profile will be used as credentials with the LDAP and should not trigger inWebo push authentication each time you send a request tio the LDAP server.

Modifying Configuration.properties file of your LDAP proxy / Minimal Configuration

ldap.proxy.port=389 (the service number of the proxy LDAP is listening to accept requests/ default )
ldap.host=LDAPServ.domain.test (IP address or Name of the LDAP server to send the request to)
ldap.port=389 (the service number of the proxy LDAP is listening to accept requests/ default )

inwebo.service.id=XXXX ( your inWebo service ID)
inwebo.service.certificate.path=C:\ProxyLDAP\inWebo_Certificate12 or./proxyLDAP/inWebo_Certificate12 (the path of the inWebo P12 certificate generated by your inWebo Administration console)
inwebo.service.certificate.passphrase=PASSPHRASE (the password/passphrase of the inWebo certificate)

Whitelisting the LDAP credentials (DN) in the Configuration.properties

ldap.proxy.whitelist.dn=CN=ReadOnly,CN=Users,DC=domain,DC=test

This configuration should be replicated on the Appliance/authentication server that will send the request to the LDAPproxy

Modifying the Appliance / authentication portal to send requests to your LDAP proxy

When configuring the LDAP server on your Appliance / Authentication portal

if an existing configuration already exists to authenticate on the LDAP server, you can duplicate and only replace the IP Address by the address of the LDAP proxy.
Be sure to verify that the LDAP Credentials (DN) / used by this appliance are whitelisted on the LDAP proxy.

Creating the Appliance / authentication portal configuration to send request to your LDAP proxy

if there is no existing profile / Basically you have to indicate the following information:

you have to indicate for a new LDAP authentication server:
the IP address of the LDAP proxy
the LDAP proxy service number (as indicated previously)
the Base DN of the LDAP server ex: DC=domain,DC=test
the group DN of the LDAP users if existing ex: CN=inWebo,OU=New_York,
the LDAP credentials DN used previously (ldap.proxy.whitelist.dn) CN=ReadOnly,CN=Users,DC=domain,DC=test
with the corresponding password
