Update anonymous access ACI so that no users besides Trust Admins
users can read AD Trust key attributes (ipaNTTrustAuthOutgoing,
ipaNTTrustAuthIncoming). The change is applied both for updated
IPA servers and new installations.

Check to see if NSS is initialized before trying to do so again.
If we are temporarily creating a certificate be sure to delete it in order
to remove references to it and avoid NSS shutdown issues.
In the certificate load validator shut down NSS if we end up initializing
it. I'm not entirely sure why but this prevents a later shutdown issue
if we are passed the --ca-cert-file option.

Major changes ipa-client-install:
* Use GSSAPI connection to LDAP server to download CA cert (now
the default method)
* Add --ca-cert-file option to load the CA cert from a disk file.
Validate the file. If this option is used the supplied CA cert
is considered definitive.
* The insecure HTTP retrieval method is still supported but it must be
explicitly forced and a warning will be emitted.
* Remain backward compatible with unattended case (except for aberrant
condition when preexisting /etc/ipa/ca.crt differs from securely
obtained CA cert, see below)
* If /etc/ipa/ca.crt CA cert preexists the validate it matches the
securely acquired CA cert, if not:
- If --unattended and not --force abort with error
- If interactive query user to accept new CA cert, if not abort
In either case warn user.
* If interactive and LDAP retrieval fails prompt user if they want to
proceed with insecure HTTP method
* If not interactive and LDAP retrieval fails abort unless --force
* Backup preexisting /etc/ipa/ca.crt in FileStore prior to execution,
if ipa-client-install fails it will be restored.
Other changes:
* Add new exception class CertificateInvalidError
* Add utility convert_ldap_error() to ipalib.ipautil
* Replace all hardcoded instances of /etc/ipa/ca.crt in
ipa-client-install with CACERT constant (matches existing practice
elsewhere).
* ipadiscovery no longer retrieves CA cert via HTTP.
* Handle LDAP minssf failures during discovery, treat failure to check
ldap server as a warninbg in absebce of a provided CA certificate via
--ca-cert-file or though existing /etc/ipa/ca.crt file.

Define post-update plugin to upload public CA certificate to IPA LDAP server.
The plugin includes also update file that creates default container for the
certificate.
|
|
|
|
|

This will later allow clients to securely download the CA cert by
performaing mutual auth using LDAP with GSSAPI

IPA installer sometimes tries to connect to the Directory Server
via loopback address 127.0.0.1. However, the Directory Server on
pure IPv6 systems may not be listening on this address. This address
may not even be available.
Rather use the FQDN of the server when connecting to the DS to fix
this issue and make the connection consistent ldapmodify calls which
also use FQDN instead of IP address.

When either dirsrv or krb5kdc is down, named service restart in
ipa-upgradeconfig will fail and cause a crash of the whole upgrade
process.
Rather only report a failure to restart the service and continue
with the upgrade as it does not need the named service running. Do
the same precaution for pki-ca service restart.

LDAP updates were sorted by number of RDNs in DN. This, however,
sometimes caused updates to be executed before cn=schema updates.
If the update required an objectClass or attributeType added during
the cn=schema update, the update operation failed.
Fix the sorting so that the cn=schema updates are always run first
and then the other updates sorted by RDN count.

When CRL files are being migrated to a new directory, the upgrade
log may contain an error message raised during MasterCRL.bin symlink
migration. This is actually being caused by `chown' operation which
tried to chown a symlinked file that was not migrated yet.
Sort migrated files before the migration process and put symlinks
at the end of the list. Also do not run chown on the symlinks as
it is a redundant operation since the symlinked file will be
chown'ed on its own.

The Expires attribute in a cookie is supposed to follow the RFC 822
(superseded by RFC 1123) date format. That format includes a weekday
abbreviation (e.g. Tue) which must be in English according to the
RFC's.
ipapython/cookie.py has methods to parse and format the Expires
attribute but they were based on strptime() and strftime() which
respects the locale. If a non-English locale is in effect the wrong
date string will be produced and/or it won't be able to parse the date
string.
The fix is to use the date parsing and formatting functions from
email.utils which specifically follow the RFC's and are not locale
sensitive.
This patch also updates the unit test to use email.utils as well.
The patch should be applied to the following branches:

In summary this patch does:
* Follow the defined rules for cookies when:
- receiving a cookie (process the attributes)
- storing a cookie (store cookie + attributes)
- sending a cookie
+ validate the cookie domain against the request URL
+ validate the cookie path against the request URL
+ validate the cookie expiration
+ if valid then send only the cookie, no attribtues
* Modifies how a request URL is stored during a XMLRPC
request/response sequence.
* Refactors a bit of the request/response logic to allow for making
the decision whether to send a session cookie instead of full
Kerberous auth easier.
* The server now includes expiration information in the session cookie
it sends to the client. The server always had the information
available to prevent using an expired session cookie. Now that
expiration timestamp is returned to the client as well and now the
client will not send an expired session cookie back to the server.
* Adds a new module and unit test for cookies (see below)
Formerly we were always returning the session cookie no matter what
the domain or path was in the URL. We were also sending the cookie
attributes which are for the client only (used to determine if to
return a cookie). The attributes are not meant to be sent to the
server and the previous behavior was a protocol violation. We also
were not checking the cookie expiration.
Cookie library issues:
We need a library to create, parse, manipulate and format cookies both
in a client context and a server context. Core Python has two cookie
libraries, Cookie.py and cookielib.py. Why did we add a new cookie
module instead of using either of these two core Python libaries?
Cookie.py is designed for server side generation but can be used to
parse cookies on the client. It's the library we were using in the
server. However when I tried to use it in the client I discovered it
has some serious bugs. There are 7 defined cookie elements, it fails
to correctly parse 3 of the 7 elements which makes it unusable because
we depend on those elements. Since Cookie.py was designed for server
side cookie processing it's not hard to understand how fails to
correctly parse a cookie because that's a client side need. (Cookie.py
also has an awkward baroque API and is missing some useful
functionality we would have to build on top of it).
cookielib.py is designed for client side. It's fully featured and obeys
all the RFC's. It would be great to use however it's tightly coupled
with another core library, urllib2.py. The http request and response
objects must be urllib2 objects. But we don't use urllib2, rather we use
httplib because xmlrpclib uses httplib. I don't see a reason why a
cookie library should be so tightly coupled to a protocol library, but
it is and that means we can't use it (I tried to just pick some isolated
entrypoints for our use but I kept hitting interaction/dependency problems).
I decided to solve the cookie library problems by writing a minimal
cookie library that does what we need and no more than that. It is a
new module in ipapython shared by both client and server and comes
with a new unit test. The module has plenty of documentation, no need
to repeat it here.
Request URL issues:
We also had problems in rpc.py whereby information from the request
which is needed when we process the response is not available. Most
important was the requesting URL. It turns out that the way the class
and object relationships are structured it's impossible to get this
information. Someone else must have run into the same issue because
there was a routine called reconstruct_url() which attempted to
recreate the request URL from other available
information. Unfortunately reconstruct_url() was not callable from
inside the response handler. So I decided to store the information in
the thread context and when the request is received extract it from
the thread context. It's perhaps not an ideal solution but we do
similar things elsewhere so at least it's consistent. I removed the
reconstruct_url() function because the exact information is now in the
context and trying to apply heuristics to recreate the url is probably
not robust.

Fedora 16 introduced chrony as default client time&date synchronization
service:
http://fedoraproject.org/wiki/Features/ChronyDefaultNTP
Thus, there may be people already using chrony as their time and date
synchronization service before installing IPA.
However, installing IPA server or client on such machine may lead to
unexpected behavior, as the IPA installer would configure ntpd and leave
the machine with both ntpd and chronyd enabled. However, since the OS
does not allow both chronyd and ntpd to be running concurrently and chronyd
has the precedence, ntpd would not be run on that system at all.
Make sure, that user is warned when trying to install IPA on such
system and is given a possibility to either not to let IPA configure
ntpd at all or to let the installer stop and disable chronyd.

Modify the default IPA CA certificate profile to include CRL and
OCSP extensions which will add URIs to IPA CRL&OCSP to published
certificates.
Both CRL and OCSP extensions have 2 URIs, one pointing directly to
the IPA CA which published the certificate and one to a new CNAME
ipa-ca.$DOMAIN which was introduced as a general CNAME pointing
to all IPA replicas which have CA configured.
The new CNAME is added either during new IPA server/replica/CA
installation or during upgrade.
