726438 – sssd doesn't honor ldap supportedControls

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Joshua Roys 2011-07-28 15:16:21 UTC

Created attachment 515750 [details]
sssd debug logs

Description of problem:
sssd forgets about the supportedControls retrieved from the rootDSE.


Version-Release number of selected component (if applicable):
sssd-1.5.1-34.el6.2.x86_64


How reproducible:
setup a ldap server with server-side password controls.


Steps to Reproduce:
1. setup 389-ds w/server-side pw controls
2. create an account and set the password
3. change the expiration date to within the expiration warning period
4. turn sssd debugging way up

  
Actual results:
see attached log


Expected results:
things like password expiration warnings should work


Additional info:
irc.freenode.net/#sssd:
<roysjosh> hello all.  I'm having some trouble with LDAP server-side password policy.  with debugging on, I get: [sdap_control_create] (3): Server does not support the requested control [1.3.6.1.4.1.42.2.27.8.5.1].  but a search of supportedControls on the rootDSE shows this control.  this means that I don't get warnings when passwords are about to expire, etc.
<roysjosh> and further debugging shows sssd getting that control: [sdap_set_rootdse_supported_lists] (1):  10 : 1.3.6.1.4.1.42.2.27.8.5.1
<roysjosh> sssd-1.5.1-34.el6.2, by the way
<roysjosh> also, for a possible future enhancement, 389-ds returns a control for expiration notification that sssd doesn't handle: [simple_bind_done] (9): Server returned control [2.16.840.1.113730.3.4.5].
<roysjosh> I don't think the supported controls are ever copied from the main connection to the binding connection...?
<roysjosh> I also have debugging in the loop in sdap_check_sup_list which doesn't print out anything
<sgallagh> sdap_connect_send() is *supposed* to re-request the RootDSE, I think.
<sgallagh> Let me check
<roysjosh> sdap_cli_connect_send does
<roysjosh> sgallagh, ^
<sgallagh> Ahh, ok.
<sgallagh> I see the problem, then.
<sgallagh> You're right, we should be either re-requesting the RootDSE or copying it from the original connection.
<sgallagh> roysjosh: Please file a Bugzilla with this information and we'll get it fixed.
