It was future-proofing. I'm fine with changing the URI, it is

+1 for moving to /ipa/smartproxy/rest, we will want a complete REST
in ipa/rest/ in the future. I rather opened a ticket to track that:
I think I've addressed most of Petr's suggestions with the exception
global ipa handle and I stuck with *args, **options as this is
standard in IPA calls.
The gssproxy.conf.snippet just makes it easier to copy/paste. I can
drop it if
you want, I suppose it is duplication.
Note that I ran this past the Foreman design again and as a result
another interface, /realm. It was my understanding that this Foreman
wasn't set into stone but a patch is working its way through their

class handles it out of the box.
I also updated the design page a bit to reflect some of the changes
Right now there are no plans to backport python-kerberos to F20.
I will leave functional testing to others, I just read the code. I am
quite concerned about the positioning, naming and "branding" of this
1) Package name
Currently, it is a host/hostgroup smartproxy, primarily for Foreman
Packaging it as freeipa-server-smartproxy may be ok, but only if we
plan to use
this proxy for all other projects. I.e. if we one day implement user
smartproxy, it would need to be part of this otherwise it would lead
organization, like having freeipa-server-smartproxy and
freeipa-server-smartproxy-users packages. Maybe it should be named
2) ipa-rest stuff
We have ipa-rest script, ipa-rest.conf, ipa-rest.service, ipa-rest
However, I have the same concerns as above. This is too general
conflict with future core server needs (like when we implement core
interface - #4168). Let us name it consistently with package name:
The same for binary, man, ...
3) Man pages
The same point, you brand it as "IPA REST server". This is too
To sum it up - let us chose one name/brand of this feature and let's
consistently in FreeIPA infrastructure - subpackage name,
subdirectory in ipatests, man, conf, script, names in man pages.
I think it should be "host"
then we will be able to add other smart proxies and then combine them
into one ipa-smartproxy package later if needed.
This would imply we actually run separate servers for the various
commands. Given that right now we're focused on just the Foreman use
cases I think ipa-smartproxy is sufficient.
For our purposes the smartproxy is just a thin wrapper around the IPA
API. It is extensible for our needs, we just don't need to yet. But if
we did, we'd do so within the cherrypy server and everything would be
Are you saying that we will just extend this smart proxy for other use
cases like users and others?
It all depends on the use case. If we're talking Foreman then yes. If
something else, then we'll discuss it at the time, but it still may be
able to be included.
The IPA Foreman smart proxy is distinguished by a couple of things:
- listens on port 8090, only on localhost
- is unauthenticated
- uses the /realm URI namespace
I'm exposing hosts and hostgroups as well, but per the spec that
Dominic came up with only /realm/:domain is required and affects only
We can stick this behind Apache to get authentication, even on a
specific URI if we want/need to, but the basic REST stuff can still be
handled by cherrypy.
We'll need to balance complexity of mixing things vs the complexity of
code duplication in multiple servers, unless we come up with some sort
of REST server class where we just instantiate whatever we need. But
that is for the future.
But if it is specific for Foreman then it should have a generic name. I
agree with Martin here.
I have the feeling we're in basic agreement.
smartproxy is the Foreman name. I'm not pushing back against renaming, I'll
have a new patch out shortly doing just that. I'm just pushing back against
renaming it too deeply. I'm going with ipa-smartproxy.
The point is that smartproxy is a good name to be reused outside foreman. So
rather than assuming that "smartproxy" is foreman specific we can go with:
host proxy or host smart proxy - for this use case
user proxy or user smart proxy - for use cases like User provisioning systems
DNS proxy or DNS smart proxy - ...
DHCP proxy or DHCP smart proxy - ...
and so on
We need to establish a good pattern that we will be able to easily extend.
+1, this was exactly my goal. It is easy to name and organize things now,
difficult to do when it is live upstream and/or integrated with Foreman.
I think the key for the right naming is a fact if this is really specific to
Foreman or it is a truly general design usable also in other use cases. If
Foreman-specific, I would go with freeipa-server-smartproxy-host or similar.
If general, we can go with
The proxies may share the framework and only expose the requested part of the
tree - which in advance gives you an option for an API separation, as compared
to general freeipa-server-smartproxy.
I still don't get the point of this. Are you proposing having 3
different servers, each providing a unique service? Or one service that
one can turn on/off features, or something else? Do you envision this as
3 separate subpackages?
There is no "framework" in my current patch, it is a cherrypy server
that exposes parts of IPA on a given URI. It is the thinnest of layers.
