Gladly ;-)

ok, so I restarted the httpd service then I could use ipa service-show:

$ ipa service-show ldap/kdc01.unix.iriszorg.nl |grep Serial
  Serial Number: 175
  Serial Number (hex): 0xAF
bash-4.1$ ipa service-mod --certificate= ldap/kdc01.unix.iriszorg.nl

bash-4.1$ sudo ipa-getcert resubmit -i

"IPA".
bash-4.1$ sudo getcert list

the certificate is gone:
$ ipa service-show ldap/kdc01.unix.iriszorg.nl

But then I thought, what the hell, let's try again, restarted httpd,
resubmitted it, and now it did work ;-)

$ ipa service-show ldap/kdc01.unix.iriszorg.nl

So I could revoke the old one:

$ ipa cert-revoke 175
  Revoked: True

and now getcert list shows the certificate is ok:

Number of certificates and requests being tracked: 8.
Request ID '20121107212513':
        status: MONITORING
        stuck: no

        certificate:

        pre-save command:
        post-save command: /usr/lib/ipa/certmonger/restart_dirsrv
UNIX-IRISZORG-NL
        track: yes
        auto-renew: yes

So one down, two to go, it seems.
