[TYPO3-Solr] Indexing of restricted pages

[redacted user]

After a few more tests everything works fine, now.

The exception was caused by a faulty user function defined in [FE][pageNotFound_handling] (Install tool -> All configuration). This function did redirect all users, which are not logged on, to a login form. So it's not a solr related problem I guess. Hopefully this hint is helpful for someone else.

Thanks for your help, Olivier!

Cheers,
Thomas
