I am trying to set up an 'in-house' TMGMT Server (as was described at DrupalCon Prague 2013) for some TMGMT Client websites. The process seems to require registration at the TMGMT Directory (https://www.tmgmt.org/register/ts-owner) but unfortunately that server has been offline for a while.

Is there a way to bypass the TMGMT Directory registration and generate my own key pairs?

Many thanks
