# Installation of the Authentication Service SSO

# Requirements

  • installed 4App Core Engine, version 3.8.x or higher for the possibility to download. The web service supports version 3.6 or higher, though.
  • installed 4App Authentication Provider LDAP (not required for installing this 4App, but necessary for its usage).

# Further Requirements

  • the downloaded web service file must be installed on a Windows server connected to the domain for which SSO should be processed
  • Java JDK 17
  • Apache HTTP Server ("HTTPD")
  • Apache Tomcat 9 (version 10 is currently not supported)

# Installation of the 4App

The Authentication Service SSO is available as a separate 4App (4allportal-authentication-service-sso) and can be downloaded and installed via the app management in the administration area. After installation, activate the 4App and restart the system.

You now find new admin snap-in Authentication/LDAP provider SSO extension in the administration area of your 4ALLPORTAL. The snap-in allows to download the required web service file.

Installation and configuration instructions for Java, Apache, Tomcat, and the web service file can be found here.
