Hello, I have a Ubuntu 14.04/Apache2 server with ISPConfig installed and several vhosts, some of them already with SSL certificates, all running smoothly. Half an hour ago I tried installing privacyIDEA following their official documentation (http://privacyidea.readthedocs.org/en/latest/installation/ubuntu.html). However, when the installation finished, all my websites (including ISPConfig) were no longer available or giving SSL errors. Could anyone help me with pointers what I should do in order to get privacyIDEA installed without screwing with my existing setup and, if possible, to make its web interface available only on the local network? Thanks a lot in advance!
