Renew Certificate from Windows NDES get pkcs7 failure

[jmccanta]

I can get a certiifcate against a Windows NDES server (with one-time passords) using:

scepclient-linux-amd64 -server-url https://ndes.example.com/certsrv/mscep/mscep.dll/pkiclient.exe -private-key $PWD/local.key -certificate $PWD/me2.crt -debug -cn $(hostname -f) -country US -locality Seattle -organization 'example' -province 'Washington' -ca-fingerprint '71AC3A84 DAAEC5B5 FDDCCD64 3ED6B79D' --challenge 48D232ED9EEC123D

However, I am unable to renew this certificate. I have tried:

scepclient-linux-amd64 -server-url https://ndes.example.com/certsrv/mscep/mscep.dll/pkiclient.exe -private-key $PWD/local.key -certificate $PWD/me2.crt -debug

badMessageCheck means the server didn't like the renewal request for whatever reason. The server is probably logging the actual reason for the failure, which would be useful in debugging here.

@jmccanta were you able to get more information/logs from the NDES server?
