Too many smart-cards inserted. Good thing: no need to throw them away

image002_thumb[2]Some time ago I used to issue certificates on Aladdin (now SafeNet) eToken  smart-cards through a CA web-nterface. Occasionally it was hard to accomplish, because when I tried to do that I received the following error:

"Too many smart-cards inserted. please insert only one smart-card"

Wow! But I need two:

  • one – eToken with a certificate for enrollment
  • the second – for a new certificate

May be CA thinks that I have too much of them generally and I need throw away them? No, fortunately (they cost much when in bulk, you know) it is not the case. Moreover, there is just a simple solution to the problem: set the registry entry NoDefaultKeyContainer in HKLM\SOFTWARE\Aladdin\eToken\MIDDLEWARE\CAPI\IEXPLORE.EXE (or create one, if you don’t have it) to the DWORD value 00000000:

That always solved the problem for me.
