All the 3 ipa servers return u,u,Pu for auditSigningCert

# certutil -L -d /var/lib/pki-ca/alias/

I have restarted the dirsrv for PKI-IPA, and the pki-cad service on all 3 IPA servers.

After I restarted dirsrv, pki-cad and then the httpd on ipa01 the status of the request is now:

Request ID '20120119194518':
	status: CA_UNREACHABLE
	ca-error: Server failed request, will retry: 907 (RPC failed at server.  cannot connect to
'https://ipa01.dns.domain:443/ca/agent/ca/displayBySerial': [Errno -12269]
(SSL_ERROR_EXPIRED_CERT_ALERT) SSL peer rejected your certificate as expired.).
	stuck: yes
	key pair storage:
type=NSSDB,location='/etc/dirsrv/slapd-DNS-DOMAIN',nickname='Server-Cert',token='NSS Certificate
DB',pinfile='/etc/dirsrv/slapd-DNS-DOMAIN//pwdfile.txt'
	certificate: type=NSSDB,location='/etc/dirsrv/slapd-DNS-DOMAIN',nickname='Server-Cert',token='NSS
Certificate DB'
	CA: IPA
	issuer: CN=Certificate Authority,O=DNS-DOMAIN
	subject: CN=ipa01.dns.domain,O=DNS-DOMAIN
	expires: 2014-01-19 19:45:18 UTC
	eku: id-kp-serverAuth,id-kp-clientAuth
	pre-save command:
	post-save command:
	track: yes
	auto-renew: yes

However I cannot find the certificate that's expired?
