Simo, Adam and I had a long discussion on IRC regarding the time rules
today (complete log attached).
The short version is that we're going to continue (mostly) with the
current grammar for the time rules, with a few changes.
1) We need to replace week-of-the-month with day-of-the-septet. This day
should not be a range or multi-valued to eliminate confusion
2) We need to replace the time range with a duration
3) We should add startDate and endDate as attributes on the HBAC object
(separate from the accessTime). I propose these should be in LDAP
generalizedTime so that it's possible to construct filters around them.
This effectively sets the beginning and end of a periodic schedule.
I've drawn up a new grammar definition and published it to the SSSD wiki
(not currently linked from anywhere):

Please review and give feedback.

Proposed changes to the HBAC grammar
by Stephen Gallagher
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
During a discussion today about how to represent the HBAC grammar in the
FreeIPA GUI, it became apparent that there was a limitation in the
grammar. Specifically, it's not possible to describe in a non-ambiguous
way "The first Wednesday of the month".
Right now, this would be described by:
accessTime: periodic monthly week 1 day 3 0800-1700
However, this literally means "Wednesdays that appear as the first week
on a wall calendar". Meaning that if the month began on a Thursday, this
rule would not fire this month. Thus it's not behaving in a way that
would be reasonably expected by a user.
After extended discussion, Simo, Ben and I discussed replacing this
week-of-the-month concept with a septet-of-the-month concept instead.
This would be described by:
accessTime: periodic monthly septet 1 day 3 0800-1700
and would literally translate as "The wednesday that exists within the
first septet of the month". The first septet being the range of day 1
through day 7, the second septet being day 8 through 14, and so forth.
We all feel that this would map closer to a user's expectation when
describing "the Nth Wednesday of the month", since it's a guarantee that
Wednesday will appear only once within a septet.
This will require two changes to the HBAC schema. First of all, we plan
to drop the week-of-the-month concept entirely and replace it with
septet-of-the-month. This is being done to eliminate the ambiguity
entirely. Secondly, we will need to describe day-of-the-septet in the
grammar (where the day of the septet describes the name of the weekday,
and not its numerical position within the septet, as that would be a
useless and complex duplication of the day-of-the-month concept).
In a related note, we also discussed how to handle describing activity
windows that cross the midnight boundary. It's my recommendation that we
should handle examples like the following by breaking them into two
separate accessTime attributes, one that describes the portion preceding
midnight and describes the set of days wherein the block starts, and a
second accessTime attribute that is offset by one day and describes the
portion taking place after midnight.
Second-shift (17:00-01:59, M-S*) *starts Monday, ends Saturday morning
becomes
accessTime: periodic weekly day 1-5 1700-2359
accessTime: periodic weekly day 2-6 0000-0159

[PATCH] Fix authentication queue code for proxy auth
by Stephen Gallagher
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
We weren't decrementing the count of in-progress authentication
request child processes when they completed successfully. With
this patch, we will now guarantee that the process count is
accurate and that queued requests will be started when a slot is
freed up.
