In krb5 1.7 and later, the stash file (/var/kerberos/krb5kdc/.k5.$REALM
on Fedora) is created in the regular keytab format instead of the older
less-portable one. Based from comments and code in kt_file.c, here's a
change to try to recognize that case (the file starts with a magic
number) and read the master key from Python.
The KDC will still read either format, so I left the bits that set
things up on replicas alone (advice appreciated). The patch works as
expected on my 64-bit box, both on RHEL5 (krb5 1.6.1 with a traditional
stash file) and on Raw Hide (krb5 1.7 with a keytab).

I saw this with a host where I joined a host, obtained a host
principal, kinited to that principal, then deleted the host from the
IPA server. The ticket was still valid so Apache let it through but
it failed to bind to LDAP.

Previously we only filtered None values, but it turns out that's not enough.

Installing a CA that is signed by another CA is a 2-step process. The first
step is to generate a CSR for the CA and the second step is to install
the certificate issued by the external CA. To avoid asking questions
over and over (and potentially getting different answers) the answers
are cached.

Using the client IP address was a rather poor mechanism for controlling
who could request certificates for whom. Instead the client machine will
bind using the host service principal and request the certificate.
In order to do this:
* the service will need to exist
* the machine needs to be in the certadmin rolegroup
* the host needs to be in the managedBy attribute of the service
It might look something like:
admin
ipa host-add client.example.com --password=secret123
ipa service-add HTTP/client.example.com
ipa service-add-host --hosts=client.example.com HTTP/client.example.com
ipa rolegroup-add-member --hosts=client.example.com certadmin
client
ipa-client-install
ipa-join -w secret123
kinit -kt /etc/krb5.keytab host/client.example.com
ipa -d cert-request file://web.csr --principal=HTTP/client.example.com

We want to only allow a machine to request a certificate for itself, not for
other machines. I've added a new taksgroup which will allow this.
The requesting IP is resolved and compared to the subject of the CSR to
determine if they are the same host. The same is done with the service
principal. Subject alt names are not queried yet.
This does not yet grant machines actual permission to request certificates
yet, that is still limited to the taskgroup request_certs.

We were seeing a rare deadlock of DS when creating the memberOf task because
one thread was adding memberOf in a postop while another was trying to
create an index and this was causing a PRLock deadlock.

We have to replace 05rfc2247.ldif because it contains some conflicting
attributes with DNS in some older versions of 389-DS/RHDS. This fails on
some newer versions of 389-DS/RHDS so this lets it continue installing
if the new file is not needed.

Password policy entries must be a child of the entry protected by this
ACI.
Also change the format of this because in DS it was stored as:
\n(target)\n so was base64-encoded when it was retrieved.

In order to run the tests you must put your DM password into
~/.ipa/.dmpw
Some tests are expected to generate errors. Don't let any ERROR
messages from the updater fool you, watch the pass/fail of the nosetests.

The KDC ldap plugin is very picky about the format of DNs. It does
not allow spacing between elements so we can't normalize it.

- The aci plugin didn't quite work with the new ldap2 backend.
- We already walk through the target part of the ACI syntax so skip that
in the regex altogether. This now lets us handle all current ACIs in IPA
(some used to be ignored/skipped)
- Add support for user groups so one can do v1-style delegation (group A
can write attributes x,y,z in group B). It is actually quite a lot more
flexible than that but you get the idea)
- Improve error messages in the aci library
- Add a bit of documentation to the aci plugin

This will create a host service principal and may create a host entry (for
admins). A keytab will be generated, by default in /etc/krb5.keytab
If no kerberos credentails are available then enrollment over LDAPS is used
if a password is provided.
This change requires that openldap be used as our C LDAP client. It is much
easier to do SSL using openldap than mozldap (no certdb required). Otherwise
we'd have to write a slew of extra code to create a temporary cert database,
import the CA cert, ...

External CA signing is a 2-step process. You first have to run the IPA
installer which will generate a CSR. You pass this CSR to your external
CA and get back a cert. You then pass this cert and the CA cert and
re-run the installer. The CSR is always written to /root/ipa.csr.
A run would look like:
# ipa-server-install --ca --external-ca -p password -a password -r EXAMPLE.COM -u dirsrv -n example.com --hostname=ipa.example.com -U
[ sign cert request ]
# ipa-server-install --ca --external-ca -p password -a password --external_cert_file=/tmp/rob.crt --external_ca_file=/tmp/cacert.crt -U -p password -a password -r EXAMPLE.COM -u dirsrv -n example.com --hostname=ipa.example.com
This also abstracts out the RA backend plugin so the self-signed CA we
create can be used in a running server. This means that the cert plugin
can request certs (and nothing else). This should let us do online replica
creation.
To handle the self-signed CA the simple ca_serialno file now contains
additional data so we don't have overlapping serial numbers in replicas.
This isn't used yet. Currently the cert plugin will not work on self-signed
replicas.
One very important change for self-signed CAs is that the CA is no longer
held in the DS database. It is now in the Apache database.
Lots of general fixes were also made in ipaserver.install.certs including:
- better handling when multiple CA certificates are in a single file
- A temporary directory for request certs is not always created when the
class is instantiated (you have to call setup_cert_request())

If the DNS zones already exist but don't contain our own records, add
them. This patch introduces the ipalib.api into the installers. For now,
the code is still little messy. Later patches will abandon the way we
create zones now and use ipalib.api exclusively.

This patch adds options --forwarder and --no-forwarders. At least one of
them must be used if you are doing a setup with DNS server. They are
also mutually exclusive. The --forwarder option can be used more than
once to specify more servers. If the installer runs in interactive mode,
it will prompt the user if none of these option was given at the command
line.

This also adds a new option to the template system. If you include
eval(string) in a file that goes through the templater then the
string in the eval will be evaluated by the Python interpreter. This is
used so one can do $UIDSTART+1. If any errors occur during the evaluation
the original string is is returned, eval() and all so it is up to the
developer to make sure the evaluation passes.
The default value for uid and gid is now a random value between
1,000,000 and (2^31 - 1,000,000)

If you don't want to use ldapi then you can remove the ldap_uri setting
in /etc/ipa/default.conf. The default for the framework is to use

We used to use certutil -O to determine the cert chain to trust. This
behavior changed in F-11 such that untrusted CAs are not displayed.
This is only used when we import PKCS#12 files so use pk12util -l to
display the list of certs and keys in the file to determine the nickname(s)
of the CAs to trust.

sha has been replaced by hashlib. We need to support Python 2.4 - 2.6 so
this will use hashlib if available but fall back onto sha if not.
Fortunately they use the same API for the function we need.

- Add some logging so we have a better idea of what happened if things fail
- Default to self-signed CA to trust if one is not found. This will fix
the self-signed CA case where certutil doesn't return untrusted CA's in
-O output.
- Remove unused httplib import

The ipa-replica-install script will setup the DNS if user specifies the
--setup-dns option. It will only add the zone into LDAP if the
cn=dns,$SUFFIX container doesn't exist. For now, however, we do not add
the records.

Also, small cosmetic change in dns.ldif.

This involves creating a new CA instance on the replica and using pkisilent
to create a clone of the master CA.
Also generally fixes IPA to work with the latest dogtag SVN tip. A lot of
changes to ports and configuration have been done recently.
