Preparing for Installation

Before you begin

We assume that you have

  • A working Allegra instance with administrator access

  • One or more configured LDAP servers like OpenLDAP or AD

  • Allegra configured to work with the LDAP server(s)

You need to have the REST webservices enabled in Allegra: Administration perspective > Server administration > Other tab > check: Webservice activated. If this is missing the forgot password and self registration features won’t work.

Generating the SSO configuration

The CAS Single Sign-On software uses the LDAP server(s) configured for Allegra for authentication. The corresponding configuration is generated from the Allegra LDAP configuration.

As an Allegra administrator go to Administration perspective > Server configuration > LDAP & SSO.

To generate the configuration files click on button “Generate CAS config”. From the LDAP configuration the following CAS configuration files ar being generated:

../_images/generate-cas-config.png

  • cas.properties

  • adminusers.properties

  • services/Track-1000.json

The location of these files is in /etc/cas/config for Unix based systems and in C:\etc\cas\config for Windows based systems.

In case of write permission restrictions the files will be generated in TRACKPLUS\_HOME/cas/config. From there you would have to copy them manually over to the standard locations.

File /etc/cas/config/cas.properties

This file configures the SSO server. It contains: server port, server url, ldap settings etc.

File /etc/cas/config/adminusers.properties

This file contains all users with administrator privileges. By default all Allegra administrators are SSO administrators.

File /etc/cas/config/services/Track-1000.json

Via this file you configure the server to accept Allegra as a service. By default all https services are accepted. When all https services are accepted the individual service definitions are not considered.
