Created attachment 1097229 [details] journalctl -o cat -b output Description of problem: During boot when the nslcd service is started the following is reported from nslcd: nslcd[1555]: [8b4567] <group/member="colord"> failed to bind to LDAP server ldap://DNS/: Can't contact LDAP server: No such file or directory nslcd[1555]: [8b4567] <group/member="colord"> no available LDAP server found, sleeping 1 seconds and it continues to complain: nslcd[1555]: [7b23c6] <group/member="postfix"> failed to bind to LDAP server ldap://DNS/: Can't contact LDAP server: No such file or directory nslcd[1555]: [7b23c6] <group/member="postfix"> no available LDAP server found: Can't contact LDAP server: No such file or directory nslcd[1555]: [7b23c6] <group/member="postfix"> no available LDAP server found: Server is unavailable: No such file or directory nslcd[1555]: [3c9869] <group/member="postfix"> failed to bind to LDAP server ldap://DNS/: Can't contact LDAP server: No such file or directory nslcd[1555]: [3c9869] <group/member="postfix"> no available LDAP server found: Can't contact LDAP server: No such file or directory nslcd[1555]: [3c9869] <group/member="postfix"> no available LDAP server found: Server is unavailable: No such file or directory until I restart it after boot has completed. Version-Release number of selected component (if applicable): nss-pam-ldapd-0.8.14-5.fc23.x86_64 How reproducible: 100% Steps to Reproduce: 1. Configure a host as an IPA client 2. Boot up 3. Observe errors Actual results: nslcd fails to look up LDAP results Expected results: should successfully look up LDAP results Additional info: I wonder if this problem is one of the network not being up and available when nslcd is started, given that it works fine if I restart it once boot has completed. I have attached the output of journalctl -o cat -b output for your inspection.

(In reply to Jakub Hrozek from comment #1) > > Probably. SSSD is much better suited for this kind of environments (and > better maintained...) Isn't that what an ipa-client-install should have done? I was assuming that ipa-client-install is what installed and enabled this nslcd also. To be clear, this F23 node is/should be an IPA client.

It was always meant as a fallback for systems or distributions that don't have SSSD. > > > ipa-client-install configures sssd by default. > But it has an option to use nslcd > -S, --no-sssd Do not configure the client to use SSSD for > authentication > > > To be clear, this F23 node is/should be an IPA client.
OK. So yeah. I'm starting to see that sssd and nslcd actually overlap and that you don't need the latter and it's not actually a *required* (or even recommended) component of being an IPA client. This must have been holdover from before this node was an IPA client and I was rolling my own Kerberos/LDAP/SSO infrastucture (i.e. before I got an IPA server). I will just remove it and be done with it. I guess I want to remove the "ldap" provider configuration from my nsswitch.conf lines too then, yes? They are currently subordinate (i.e. after) to my sssd provider on all of the lines they exist on, but for consistency's sake, I can just remove 'em, yes?
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
