I was there at IMC and spoke with Zakir. He was not aware of the fact
that the private keys to all the intermediate certificates are held by
the central DFN Verein, not the RAs themselves. In the case of DFN, the
intermediate certs only identify the RAs. The RAs do not carry signing
power.

It is the same at TUM, where I work, BTW.
