I'm trying to get PIV working again after i erased everything from my yk4.

I ran into some problems after testing all different things and erasing slot 1 & 2
Before i ran into troubles i found the tutorial on http://www.jupiterbroadcasting.com/8506 ... y-las-373/ and had SSH auth. with PIV working.

After i erased both slots, i imported the certificate again (yubico-piv-tool -a import-certificate -s 9a -i cert.pem ), and everything looked okay.
Code:
ssh-add -L
gives me the same public key as before
Code:
ssh-keygen -D /usr/local/lib/opensc-pkcs11.so
gives also the same pubkey
Code:
→ opensc-tool --list-readers
# Detected readers (pcsc)
Nr.  Card  Features  Name
0    Yes             Yubico Yubikey 4 OTP+U2F+CCID

Code:
→ opensc-tool -n
Using reader with a card: Yubico Yubikey 4 OTP+U2F+CCID
PIV-II card


In
Code:
/etc/ssh/ssh_config
the last line is.

Does anyone have any tips to get it working again?

I've erased everything again according to http://forum.yubico.com/viewtopic.php?f=26&t=1941
rebooted
imported pem
but now it's telling me this:

C_Sign failed: 32
no such identity: /Users/jasper/.ssh/id_ed25519: No such file or directory

When i'm passing in a wrong pin, it gives me:

I solved it.

It probably has something todo with the fact that i was importing my 'old' certificate and using cli-tools and gui through one another.

Here was my solution:
I've started
Code:
yubico PIV manager 1.1.1

tried to delete the certificate that was loaded, somehow it complained about the management while it was asking for my pin.
Then i entered a wrong for few times because i was fed up with that..
after resetting it, (all within the gui), setting a new pin, i generated a new certificate.
In terminal i tried
Code:
ssh-keygen -D /usr/local/lib/opensc-pkcs11.so
and it gave me a new pubkey.
I added that to my server and everything worked.
