One logon is enough.

The Single SignOn Applications

You can find all the needed files for your Single SignOn solution on the official TYPO3 Forge.

You will need the following things to make DirectSSO work:

  1. The SSO TYPO3 extension
  2. The SSO Agent
  3. The SSO Adapter (corresponding to the application you want to integrate)

Please note, that the documentation for each adapter is included in the adapter "folder" on forge, too. For example you can find the documentation for the mediawiki 1.14.0 adapter here.

We use the "tag" feature on forge to differentiate between the different adapter versions for the target application. So you can browse on forge for example mediawiki - tags to see the different versions.
