I'm definitely for creating a field where admin can choose a existing

possibility to create and define new time rule in dialog for creating
new HBAC. I think that mixing these two things together is like a
possibility to create a new user when you are creating a user group.
Which is mixing two different things together. I can imagine a button
like "Create HBAC and add a new time rule to it" which could store
new HBAC rule and immediately take admin to the page (or dialog)
where admin can create a new time rule with prefilled HBAC rule. But
as you write below it would be good to discuss it with some UX designer.

added a short How to Use section.
Thank you for the review! I will add some comments inline.
My idea was that we allow users prepare a few time rule objects
before filling them with the actual times.
On the high level it all makes sense.
ad LDAP schema
1) Why accessTime attribute is MAY in ipaTimeRule object class?
Does it make sense to have the object without accessTime? I do not
Also, it could be good to add description attribute to the object
incorporate it into commands (including find).
Definitely a good idea, I will work that in.
I believe that the accessTime attribute was originally brought to
IPA when there was an implementation of time policies for HBAC
objects and it's been rotting there ever since those capabilities
were removed. We may eventually use a new attribute for storage of
the time strings as accessTime by definition is multi-valued which
is not what's currently desired (although we may end up with it some
day in the future). However, I don't think any other use of
accessTime should be a problem as it's been obsoleted for a long time.
2) Besides all this, I spent few minutes in dark history of IPA. The
accessTime attribute was introduced back in 2009 in commit
"55ba300c7cb59cf05b16cc01281f51d93eb25acf" aka "Incorporate new
schema for IPAv2".
The commit does not contain any reasoning for the change but I can
the attribute is already used as MAY in old object classes
Is any of these a problem?
I'm sorry to say I have no idea. I used it for what it originally
was - a means for storing time strings at HBAC rules.
Why is it even in ipaSELinuxUserMap object class?
55512dc938eb4a9a6655e473beab587e340af55c does not mention any
reason for doing so.
I cannot see any other problem so the low-level stuff is good and
ad User interface
We need to polish the user interface so it really usable.
At least the web interface should contain some shortcuts. E.g. when
a new HBAC rule, the "time" section should contain also "something" to
immediately add new time rule so I do not need to go to time rules
then go back to HBAC page.
I'm not UX guru, but if you add button there and show dialog window to
create new timerule and then automatically assign it to the HBACrule
it may work for me :)
Similarly, dialog for rule modification should allow to easily
change all the
values, warn if time rules is shared, and also have an easy way to
'disconnect' the time rule, i.e. make a copy of it and edit only
the new copy
(instead of the shared original).
All of these points are really good.
All these are user interface things not affecting the low-level stuff.
Maybe you should sat down with some UX designer, talk about these
draw some hand-made pictures.
I will add Pavel V. to CC, we may want to discuss this.
I do not believe that this will require any changes in schema so
It definitely felt better to be writing it with all the previous
knowledge. Thank you! :-)
polish SSSD and framework implementation in meantime.
On the link below is a PROTOTYPE-patched FreeIPA that covers most
of the CLI
functionality (except for the creation of iCalendar strings from
better illustration of the design.
Honestly I did not look at the code today :-)
Overall, I'm glad to see current proposal. After so many iteration,
something which does not have any glaring problem :-)
LGTM with all previous comments
Thank you for the review, my comments are inline
(Nitpick mode enabled: True)
It may not be clear from design that client is actually SSSD, and not
IPA CLI client. Please write explicitly there that HBAC time rules are
enforced by SSSD with libical in client side sections
Did not realize that, I will add the information.
There's currently no design for the SSSD part. I think the
implementation there might be straight forward enough - add caching of
the new LDAP subtree, get the time rules from it, evaluate them at the
given HBAC rules.
Is there any design for SSSD part? If yes, it should be linked to this
(probably client section)
timerule-mod, timerule-show should show all HBAC rules that are using
it (Should be done by framework almost automatically, but explicit is
better than implicit, please make note there).
I believe framework should be already doing that but I'll check.
Perhaps just a prompt with warning showing all affected HBAC rules could
do (could it?), although I am not sure if that is kosher within the
timerule-del should prevent deletion of timerule if it is used by any
HBAC rule (we can discuss this)
WebUI: it may be nice to have warning shown when user is editing time
rule that is used by more than one HBACrule (even confirmation dialog
would be nice)
Should something like that be also in the CLI (similarly to previous point)?
(Nitpick mode enable: False)
IMO we should add timerule-test (pick correct name) to test if given
time/date value matches timerule
That seems like a reasonable idea.
Definitely, I will add that to the design, I completely forgot about
We should also extend hbac*-test with timerules (would be nice to
mention in design)
