Hello everyone.

I must implement a SSO (Single Sign On) for Elgg community site linked to a institutional site under eZ Publish.

All my user accounts are managed in eZ Publish.

It is important that users can navigate seamlessly between the two sites.

If user A is connected to the site eZ then went on Elgg website there will be automatically connected.

If User B is connected to the site Elgg then goes to the eZ website there will be automatically connected.

Most of the resources speaking SSO delegates authentication to external services (google, twiter, etc)

I have to keep off the user control

I installed an extension on my eZ site supposed to manage the SSO Repository.

Ok. But now...
How can I implement this solution?
