SSL/TLS servers don't automatically check for cert revocation. You need
to add the CRL to the 389-ds NSS database periodically. I don't know for
sure but I don't think 389-ds can use OCSP to validate incoming client
certs. There is an IPA ticket in the backlog to investigate this for the
web and ldap servers: https://fedorahosted.org/freeipa/ticket/3542

And yeah, as you discovered, managing the value of CmapLdapAttr is a
poor man's revocation.

By the way, revoking the certificate does not block applications using it
from ldap.

I can still access the ldap server using this cert/key pair *after*
revoking the certificate using ipa cert-revoke . In order to
block it I need to remove the seeAlso value of the user account, or the
certificate attribute.

I do not know if this is a security issue, but maybe worthwhile documenting
just in case.

Ah right. Because all the subjects are the same base the same map will
be used for both DS and the CA.

ok, I got it working  but it took some effort.

Let's see, in certmap.conf the config is like this out of the box:

certmap default default
#default:DNComps
#default:FilterCompse, uid
#default:verifycert on
#default:CmapLdapAttr   certSubjectDN
#default:library
#default:InitFn 
default:DNComps
default:FilterComps uid
certmap ipaca   CN=Certificate Authority,O=SUB.DOMAIN.TLD
ipaca:CmapLdapAttr  seeAlso
ipaca:verifycerton

So, there is an additional mapping for ipaca, which is handy. But the
CmapLdapAttr points to 'seeAlso', and if you change that to
usercertificate;binary (where the usercertificates are), the tomcat pki
service will no longer start because

DN: uid=pkidbuser,ou=people,o=ipaca

has this seealso attribute: CN=CA Subsystem,O=SUB.DOMAIN.TLD

so we cannot change te cmapldapattr to something else, but we can add a
seealso attribute to the user account, like cn=username,o=SUB.DOMAIN.TLD .
And then it works.

This could be very handy for web applications.

Nice. Thanks for the pointer.

Natxo

Hmm, I'm not sure if realm name "myinc.LOCAL" is a obfuscation artifact or
real configuration. As usual, attempts to obfuscate things make debugging
harder :-)

Generally it is not a good idea to have realm != uppercase primary IPA DNS 
domain.

It seems that for some reason client is failing to find KDC's addresses.

Try to run kinit in debug mode. Before you try that you might need to replace
krb5.conf on the client with following values (taken form client install log):

[libdefaults]
  default_realm = myinc.LOCAL
  dns_lookup_realm = true
  dns_lookup_kdc = true
  rdns = false
  ticket_lifetime = 24h
  forwardable = yes
  udp_preference_limit = 0
  default_ccache_name = KEYRING:persistent:%{uid}


[realms]
  myinc.LOCAL = {
pkinit_anchors = FILE:/etc/ipa/ca.crt

  }


[domain_realm]
  .prod.cloud.myinc.local = myinc.LOCAL
  prod.cloud.myinc.local = myinc.LOCAL


Then you might try following command on the not-yet-enrolled host:

Why has the naming structure changed from

Hello,

I do not know why this change was done in centos, please ask directly on 
centos related lists.


However, version ipa-server-4.2.0-15.el7_2.6.x86_64 is the latest
