Users with only local roles lose session

[nidico]

I haven't done a proper analysis, so I just write down the current symptoms.

In a current staging installation, users which only belong to a group which only has local roles assigned (moderator and initiator in this case), the session of these users automatically expires on reload of the page.

The frontend does a head request to the root resource to verify its credentials. If it fails, it throws away the credentials. Maybe this is what happens here.

Could not reproduce. Seems to be fixed.
