Use the browser to delete dual key certs from an ActivCard token.
Close the browser.
Open the card using the ActivCard utility. The utility shows that there are
still keys on the card.
If you delete certs using the utility everyting goes away.

Note that it doesn't matter whether the certs were generated on the card or
imported from a p12 file.

WFM with an iButton. Deleting a 1K dual cert from AOL deletes the cert, and it 
does not display in the Admin Utility.

Question: Stephan, do you have copies of those certs in your NSS database?

NSS does not destroy the key if it still finds certificates associated with that
key. This can happen one of two ways: 1) the card still reports the existance of
a cert with the same CKA_ID, or 2) we find a cert with the same subject in the
database. I believe the latter is a bug in NSS, which I'll supply a patch for. I
want to make sure the former is not happening as well.

Don't lookup the certs elsewhere if we can't find them on the token

This code is used for 2 things: extracting a public key from a private key, and
deciding if we are going to delete the private key from a token. The former 1)
is only used by out utilities 2) has fallbacks if the cert is not found and 3)
is depending on code that was likely to find the wrong cert anyway (the code
deleted in the patch).	For the former we want to succede only if we don't find
any certs in the token we are searching.

This patch is fine.  It may be a good idea to
before returning NULL, but I am not sure if that's
the right error code.

So Bob has a patch and Wan-Teh likes the patch.
Will you check it in?
The patch is completely within NSS, so it looks like a NSS bug.
Reassining to NSS.
Comment 9 User image Robert Relyea 2002-07-16 16:33:45 PDT
This patch has been in NSS since Feb 2002. As such is has already been moved
into NSS 3.5 long ago. I think the bug was left open waiting for a tag move.

Bob is right.  This bug is fixed in rev. 1.64 of
