Bug 1740702

We need to hook this into CA/KRA uninstaller but also a cleanup job could be done in ipa-server-upgrade.

Adding dependency on 1740697.

Re-opening as the related BZ didn't address the security domain cleanup.

Sorry about that. The CA has its own authentication system outside of IPA.

This should do the trick:

pki -d /var/lib/pki/pki-tomcat/alias -n 'subsystemCert cert-pki-ca' -C /var/lib/pki/pki-tomcat/alias/pwdfile.txt securitydomain-host-del 'CA ipa.example.test 443'

These options authenticate using the certificate that the CA uses for its LDAP binds. It has permissions to do this removal.

Take care when executing this as removing the wrong host may require re-installation of that host. I'm not aware of a way to re-create these entries.

the issue is when a replica with a CA or KRA role is uninstalled, the IPA LDAP backend keeps that replica roles references under cn=masters,cn=ipa,cn=etc,dc=idm,dc=example,dc=test so IPA and the ipa-healthcheck 's IPADogtagCertsMatchCheck test think the is a configured CA

could be tested with

cat << EOF > ~/test.api
api.Command.ping()
from ipaserver.install import cainstance
ca=cainstance.CAInstance(api.env.realm)
ca.is_configured()
EOF

cat ~/test.api | ipa console



./freeipa-healthcheck/src/ipahealthcheck/ipa/certs.py
@registry
class IPADogtagCertsMatchCheck(IPAPlugin):
...
    @duration
    def check(self):
        if not self.ca.is_configured():  <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< finds a CA role from ipaConfigString in cn=CA,cn=some-replica-hostname,cn=masters,cn=ipa,cn=etc,dc=xx
            logger.debug('CA is not configured, skipping connectivity check')
            return

        def match_ldap_nss_cert(plugin, ldap, db, cert_dn, attr, cert_nick):
            try:
                entry = ldap.get_entry(cert_dn)
...
            if not cert_matched:
                yield Result(plugin, constants.ERROR,
                             key=cert_nick,
                             nickname=cert_nick,
                             dbdir=db.secdir,
                             msg=('{nickname} certificate in NSS DB {dbdir} '
                                  'does not match entry in LDAP'))
                return False
            return True



for example on an ipaserver1 where ipaserver was removed/uninstalled:

ipa server-role-find --role="CA server"
----------------------
2 server roles matched
----------------------
  Server name: ipaserver1.idm.example.test
  Role name: CA server
  Role status: enabled

  Server name: ipaserver2.idm.example.test <<<<<<<<<<<<<<<<<<
  Role name: CA server   <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 
  Role status: configured  <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
----------------------------
Number of entries returned 2
----------------------------
[root@ipaserver1 ~]# 


ldapsearch -o ldif-wrap=no -LLLx -D "cn=directory manager" -w password -b cn=masters,cn=ipa,cn=etc,dc=idm,dc=example,dc=test cn=CA cn ipaConfigString
dn: cn=CA,cn=ipaserver1.idm.example.test,cn=masters,cn=ipa,cn=etc,dc=idm,dc=example,dc=test
cn: CA
ipaConfigString: startOrder 50
ipaConfigString: caRenewalMaster
ipaConfigString: enabledService

dn: cn=CA,cn=ipaserver2.idm.example.test,cn=masters,cn=ipa,cn=etc,dc=idm,dc=example,dc=test  <<<<<<<<<<<
cn: CA
ipaConfigString: configuredService  <<<<<<<<<<<<<<<<<
ipaConfigString: startOrder 50       <<<<<<<<<<<<<<<<<<<<<



as a workaround, the entry 
cn=CA,cn=ipaserver2.idm.example.test,cn=masters,cn=ipa,cn=etc,dc=idm,dc=example,dc=test
could probably be removed with a ldapdelete if there is really no CA installed


and there are left overs under o=ipaca for the either uninstalled or CA role removed from ipaserver2, specially in the "PKI registry" / "PKI security domain"

ldapsearch -o ldif-wrap=no -LLLx -D "cn=directory manager" -w password -b o=ipaca cn=*ipaserver2* dn
dn: uid=CA-ipaserver2.idm.example.test-8443,ou=people,o=ipaca

dn: cn=ipaserver2.idm.example.test:443,cn=CAList,ou=Security Domain,o=ipaca

dn: uid=acme-ipaserver2.idm.example.test,ou=people,o=ipaca

Marc, this is a completely different issue altogether. I've not reproduced it myself. It could have to do with the way the IPA server is being removed from rotation. `ipa server-del <host>` should clean these up.

This bug is about the dogtag-specific securitydomain capability which is what triggers the healthcheck errors because we weren't cleaning it up on uninstall.
