inWebo LDAP Proxy v1.3.0

Release note 1.3 (November 27, 2020)

Hot fix LDAP Proxy

  • Support of TLSv1.2

  • Adding a LDAP server connection timeout

  • Management of expired AD passwords


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 authentication is successful, the LDAP proxy finalizes the Bind request and the user is authenticated.



The machine hosting the proxy must have:

  • Access to the LDAP server that will be connected to the inWebo proxy

  • Internet access to reach the InWebo API


Windows or Linux

  • 64-bit environment

  • Java 8 64 bits for the version without JRE or OpenJDK 8 64 bits


  • .P12 certificate and passphrase from local Authority

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.

Tests and troubleshooting inWebo LDAP Proxy Configuration

2 additional commands are included for Linux and Windows:

Testing Push and inWebo certificate in command line

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)

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 are 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 proxy LDAP 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 file of your LDAP proxy / Minimal Configuration

ldap.proxy.port=389 (the service number of the proxy LDAP is listening to accept requests/ default ) (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 ) ( 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


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

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, you have to indicate the following information:

  • you have to indicate 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

Summary of configuration items to modify

Additional parameters for inWebo LDAP Proxy v1.3.0

In the LDAP proxy configuration section, you can now set additional parameters

Transport Layer Security (TLS) Parameters 

  • For sending requests to the LDAP proxy: ldap.proxy.cipher.protocol

  • and when forwarding the request to the LDAP:  proxy.cipher.protocol

Possible values:
  • Automatic choice of JVM: "TLS"

  • Protocol TLS v1: TLSv1

  • Protocol TLS v1.1: TLSv1.1

  • Protocol TLS v1.2: TLSv1.2

Managing requests timeouts 

You can now set timeout values for requests

For the Request timeout between the LDAP proxy and the LDAP server

Value in ms. Default 0 ( no timeout )
Setting: ldap.proxy.request.timeout

If a response is not received from the Directory Server within the timeout period, then the operation will be abandoned and an Exception error result returned.
A timeout setting of 0 disables operation timeout limits

For the Request timeout between the LDAP client and the LDAP proxy

Value in ms. Default 10000 ( 10sc )
Setting: ldap.proxy.connect.timeout

If a connection is not established within the timeout period (incl. SSL negotiation, initial bind request, and/or heart-beat), then an Exception error result will be returned.
The default operation timeout is 10 seconds and a timeout setting of 0 causes the OS connect timeout to be used.

When the timeout value is exceeded

  • An error is returned when the connection failed
    "Authentication to LDAP failed : < information>"

  • The error is logged in the LDAP Proxy log file
