| Fixed In Version: | sssd-1.5.1-46.el6 | Doc Type: | Bug Fix | ||||
| Doc Text: |
Cause: SSSD did not keep a copy of the list of supported LDAP controls during the whole LDAP operation. At the same time, it used the list of controls to determine if password expiration controls were available
Consequence: Password expiration warnings did not work because SSSD thought they were not available
Fix: SSSD always requests the expiration controls and only acts upon the controls actually being created or not.
Result: Password expiration warnings are displayed

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.
