Later in the patch you seem to be changing from needing

why that
was changed. not saying it is necessarily wrong, but why the
original
check is not right anymore ?
The original check is wrong, see
<https://fedorahosted.org/freeipa/ticket/3977#comment:23>.
The check in my patch allows SAN only if the requesting host has write
access to all of the SAN services. I'm not entirely sure if this is
right, but even if it is not, I think we should still check for write
access to the SAN services, so that access control can be (partially)
handled by ACIs.
Right, I remembered that comment, but it just says to check the right
object's managed-by, here instead you changed it to check if you can
write the usercertificate.
I guess it is the same *if* there is an ACI that gives write permission
when the host is in the managed-by attribute, is that the reasoning ?
Exactly. The ACIs that allow this by default are named "Hosts can manage
service Certificates and kerberos keys" and "Hosts can manage other host
Certificates and kerberos keys".
I think the check can be extended to users as well, so that requesting
certificate with SAN is allowed only to users which have write access to
the SAN services.
I have done the modification, see attached patches.
Sounds good to me then, thanks for explaining.
The patches also look good, but I would like someone to give them a try
for a formal ack.
OK, thanks.
Bump.
I have added stricter validation of subject alt names as well as certificate
extensions in general to the second patch.
Thanks!
Updated patches attached.
Note that you will need python-nss 0.15 in order to test, you can get a RPM for
Fedora here: <http://koji.fedoraproject.org/koji/buildinfo?buildID=514739>.
John, do you think we could build python-nss 0.15 also for Fedora 20? The fix
incorporated in it is pretty important to warrant bugfix update in bodhi. It
would also allow FreeIPA 4.0 to be installed on Fedora 20.
Also, resubmitting HTTP and LDAP Server-Cert certmonger requests does not work,
because <https://fedorahosted.org/freeipa/ticket/4370>.
This worked for me, I suspect this is a DS bug. More info in the ticket.
Now back to review of the patch:
210.4: looks ok
234.4:
1) Virtual operation "request certificate with subjectaltname" should be a
member of Certificate Administrators privilege
OK.
2) I would write "Request Certificate With SubjectAltName" with "with" instead
of "With". I.e.:
Request Certificate with SubjectAltName
OK.
3) Why is the extension check only enforced for non-hosts?
+ if not bind_principal.startswith('host/'):
+ for ext in extensions:
+ operation = self._allowed_extensions.get(ext)
+ if operation:
+ self.check_access(operation)
My tricky certmonger request passed:
# ipa-getcert request -d /etc/pki/nssdb/ -n test-san-1 -I test-san-1 -g 2048 -r
-N "cn=`hostname`" -K host/`hostname` -D test1.example.com -D test2.example.com
-E mko...@redhat.com
while when I posted the same CSR as privileged user, it was rejected:
$ klist
Ticket cache: KEYRING:persistent:962000003:962000003
Default principal: f...@idm.lab.eng.brq.redhat.com
$ ipa cert-request --principal test/`hostname` certmonger.csr
ipa: ERROR: invalid 'csr': subject alt name type RFC822 Name is forbidden
Right, I meant to NACK myself, but you were faster. Fixed.
4) Regular users cannot read Virtual Operations, so even if I assign them a
permission, command is refused:
$ ipa cert-request --principal test/`hostname` openssl.csr
ipa: ERROR: Insufficient access: No such virtual command
I think we will need to create new managed permission "Read Virtual Operations"
and assign it to "Certificate Administrators" privilege by default as this
privilege has the virtual operation permissions assigned. Petr3, what is your
take on this?
Otherwise the patch worked well for me, the authorization part looked OK. My
biggest concern was just the host/user differentiation wrt unknown
subjectaltname types.

1) I could not compile the patch set:
$ make rpms
...
if [ "" != "yes" ]; then \
./makeapi --validate; \
./makeaci --validate; \
fi
Traceback (most recent call last):

...
The rest of the notes are thus only from reading.
Sorry, last minute change gone wrong.
2) There are lines like
+ if name_type == 'Other Name (OID.1.3.6.1.5.2.2)':
or
+ if name_type not in ('DNS name',
+ 'Other Name (OID.1.3.6.1.4.1.311.20.2.3)',
+ 'Other Name (OID.1.3.6.1.5.2.2)'):
or
+ elif name_type in ('Other Name (OID.1.3.6.1.4.1.311.20.2.3)',
+ 'Other Name (OID.1.3.6.1.5.2.2)'):
Can we do something better? Getting the extension type based on it's
description seems extremely unstable to me.
These are SAN types, not extension types. Unfortunately the textual
descriptions are the only SAN type representation available in
python-nss which includes OIDs of other names.
Can we for example modify get_subjectaltname to get the type based on
CertificateExtension object's oid or oid_tag attributes?
No, see above.
I would rather see get_subjectaltname return solid type like
CERT_EXTENSION_DNS_NAME defined in pkcs10.py than consumers comparing
descriptions. It would be more readable, too.
Done.

For each SAN in a request there must be a matching service entry writable by
