ESSO Installation II

Introduction

Soffid ESSO is a full Enterprise Single Sign on solution.

Here you can find the details about the ESSO +3.5.0-enterprise installation.

Supported platforms

Soffid ESSO supports Windows XP or later workstations.

Interactive installation

To install Soffid ESSO, you must follow these steps:

1. Download the latest available installer version from: Soffid Download Manager.
2. Run it as administrator. Once the interactive installation has finished, a message window will notice you:
   
   
   
3. Finally, the system will prompt you to configure Soffid ESSO. This prompt will not be shown on updates or silent installations.
   

   
   

   

   
   
4. After configuring the system, it's required to reboot the computer.

Interactive configuration

1. Once you start to configure, you need The first task to enter the Soffid Identity Provider URL and fetch its digital certificate. 

2. Then you need to configure the ESSO profile in your Identity Provider

For more information you can visit the following page: https://bookstack.soffid.com/books/federation/page/esso

3. And finally, you can configure the Adaptive authentication rules

 

 

Silent installation

In order to do a silent installation you can execute the installer from command line with the following parameters:

-q or /q: Quiet installation

-server [url] or /server [url]: to configure the synchronization server URL.

-force or /force: force the installation even if a restart is pending. Not recommended.

-nogina or /nogina: do not modify previos GINA. In this version, this parameter only applies in first installation.

Example:

C:\> soffidesso.exe -q -server https://server.domain.local:760 -force -nogina

Smart update

To assist in massive deployment scenarios, smart update swich can be set to prevent Soffid to reinstall componenents when the installer version matches the already installed one. This switch does not affect to new installations.

-smartupdate or /smartupdate: Smart update installation 

Example:

C:\> soffidesso.exe -q -server https://server.domain.local:760 -force -nogina -smartupdate

MSI Package

MSI Installation is also available for enterprise customers.

To customaize configuration parameters, the PARAM variable can be used:

Example:

C:\> msiexec /i soffidesso.mssi PARAM="-q -server https://server.domain.local:760 -force -nogina -smartupdate"

Registry configuration entries

The system stores all its settings in the registry branch HKLM\Software\Soffid\esso. The values used are as follows:

Startup process

Windows XP GINA logon

Soffid GINA is an optional part of Soffid ESSO. It's features are:

• Allows users to log on using smart cards. The digital certificates can be auto enrolled as long as there is a method to know which user it belongs to.

• Allows authorized users to log on with Local Administrator privileges.

Windows Vista Credential Provider

Soffid Credential Provider is an optional part of Soffid ESSO. It's features are:

• Allows users to log on using smart cards. The digital certificates can be auto enrolled as long as there is a method to know which user it belongs to.

• Allows authorized users to run with Local Administrator privileges.

Soffid session startup

After being identified by Windows, the Soffid session startup takes place. Either sequentially or in parallel to desktop startup, the Soffid ESSO session manager (named KojiKabuto after the best ever hero) is the responsible for making the following steps.

Update settings

KojiKabuto will contact Soffid servers o update registry entries using the system configuration introduced at Soffid console (LogonEntry, OfflineEntry, SSOServer, seycon.https.port)

Kerberos handshake

If it's enabled by system administrator, Soffid Synchronization server and the user desktop will perform a Kerberos handshake. If the Credential token shown by user desktop is accepted by any managed Active Directory, Soffid will accept that credential as a prove of identity.

In order to do that handshake, Soffid will create an special user named SEYCON_xxxx for each one of the synchronization servers involved in the login process.

Manual login

If it's enabled by system administrator, or Kerberos handshake has failed, the user will have the chance to enter it's user name and passwords. They will be verified by synchronization server against its internal user database.

Coordinates card

Once logged in, KojiKabuto requested permission to log. At this time, synchronization server could issue a coordinates card challenge. If the user fails to enter the right value for the coordinates requested, the Soffid session will be canceled.

Multiple sessions prevention

At this phase, Synchronization Server will check if the user has any other, not linked, session. If there is any other active session, and the user has not been granted the capability to open more than one (at Soffid console), the system will notice it to both, the new session and the ancient one.

Finally, the new session will take the decision to close the ancient one or to give up. If the user chooses to close the ancient one, the later will show a prompt, and its user will have 30 seconds to answer if he agrees to close that session. Usually the user has left the ancient session open and no user will be present at the ancient session. So, after 30 seconds the session will be closed and the new one will proceed.

SSO Rules activation

Once the session has been created, the SSO rules present at Soffid Console will be compiled and loaded into the Windows Session. Since this moment, every application launched will have its credentials automatically fullfilled.

Startup script

The workstation connects to Synchronization Server to get the session logon script (LogonEntry registry entry with deafault value "Logon"), and the session offline script (registry entry "OfflineEntry" with default value "offline"), which will be executed at next logon whether no Synchronization server is reachable.

The offline script is stored at %ProgramFiles%\SoffidESSO\Cache\offline.mzn file.

Afterwards, the application menu is populated using the application entries configured at Sofifd Console.

Desktop start

Unless the system configuration enables the user to use the desktop before opening the Soffid Sesion, the Desktop is started right now. Otherwise, the desktop would have been started at the initial steps.

System operation

Once the session is started, Soffid ESSO has two main tasks to do:

First. Timely keeps in touch with Synchronization server to confirm the validity of the soffid session.

Second.  Performs injection or user names and password to applications, based on the SSO rules bound to each application entry point the user is authorized to execute.\

Enforcing browser addons

Modern browsers, apply certain restrictions to automatically enable browser addons without user intervention:

Google chrome

Google chrome extension is automatically enabled, but requires internet access, as Chrome is going to download the addon directly from Chrome store rather than using the locally installed version. This addon is compatible with Microsoft Edge.

Mozilla Firefox

There is a Mozilla firefox group policy to automatically enable any extension. Follow this link to get it:  https://github.com/mozilla/policy-templates/releases/download/v1.11/policy_templates_v1.11.zip

You can alternatively, add the following registry key:

HKEY_LOCAL_MACHINE\Software\Policies\Mozilla\Firefox\Extensions\Locked\1 = "esso@soffid.com"

Internet Explorer (deprecated)

As well, there is a group policy for Internet Explorer. Please, follow this Microsoft link to get it: https://docs.microsoft.com/es-es/internet-explorer/ie11-deploy-guide/enable-and-disable-add-ons-using-administrative-templates-and-group-policy
