koji rebuild refuses due to sslv3 certificate expire

[Mamoru Tasaka]

Hello.

I want to send a build queue of jd to koji, however
it is refused with returning error messages below:

---------------------------------------------------
[tasaka1 at localhost devel]$ LANG=C make build
<class 'OpenSSL.SSL.Error'>: [('SSL routines', 'SSL3_READ_BYTES', 'sslv3 alert certificate
expired'), ('SSL routines', 'SSL3_WRITE_BYTES', 'ssl handshake failure')]
make: *** [koji] Error 1
---------------------------------------------------

I even re-downloaded a new client certificate and
now my ~/.fedora.cert says:
---------------------------------------------------
        Issuer: C=US, ST=North Carolina, L=Raleigh, O=Fedora Project, OU=Upload Files,
CN=cvs.fedora.redhat.com/emailAddress=webmaster at fedora.redhat.com
        Validity
            Not Before: May 15 05:36:04 2007 GMT
            Not After : May 14 05:36:04 2008 GMT

CN=mtasaka/emailAddress=mtasaka at ioa.s.u-tokyo.ac.jp
---------------------------------------------------

What can I do for this failure?
