filter_users using user id
by Francois Rigault 22 Mar '25

22 Mar '25

Greetings, we run some podman containers that come with their own local users, such as this one: ironic-inspector:x:42461:42461::/var/lib/ironic-inspector:/usr/sbin/nologin when running a top on the server, top tries to resolve the user name for that id and fails, however there is still a BE_REQ_USER request sent: (2022-12-30 22:42:33): [be[MY.DOMAIN.NET]] [dp_get_account_info_send] (0x0200): Got request for [0x1][BE_REQ_USER][idnumber=42461] I would hope to get rid of these requests against the domain. unfortunately in MY.DOMAIN.NET there are uids below and above this number, so I cannot rely on the "min_id" parameter to filter users. I would like to know if it is possible to support using user ids in the [nss] filter_users to prevent those user requests to the domain, or if anyone has any other suggestion. I increased the entry_negative_timeout to reduce the number of queries, but filtering them out entirely would be even better. Thank you!

Starting SSSD without root
by Tero Saarni 09 Apr '24

09 Apr '24

Hi, I'm trying to run SSSD inside docker container without root user. The container is executed in OpenShift cluster which does not allow running as root inside container. SSSD requires root and checks for this specifically. Is there any workaround for this? I believe the limitation is implemented for security reasons, in order to have most critical parts executed as root and have it drop privileges for other parts but this now completely blocks using SSSD in the above environment. -- Tero

sssd-pac.service fails to start after Debian 12 upgrade (fatal error setting up backend connector)

Doubt about integration between Samba 4 and OpenLDAP
by Cairo Campos 11 Aug '23

11 Aug '23

I need to continuously synchronize OpenLDAP users and passwords with a Samba 4 DC. However, this doesn't seem to be a good idea due to incompatibilities. Searching the internet, I saw some pages mentioning SSSD, so that I can use OpenLDAP as the basis of authentication for Samba 4. Currently, my production Samba 4 domain uses internal LDAP and DNS. I wanted material or documentation that showed me how to make the switch to using SSSD robustly. Can you help me?

best practice, using machine-account keytab for service SPNs
by Stefan Bauer 08 Aug '23

08 Aug '23

Dear Users, i really love SSSD and also the auto-renewal of the host-keytab file. On many hosts we add the SPNs HTTP/ SQL/... directly to the machine-account in Active-Directory. This is all fine and works. However i have a bad feeling about letting services read the keytab file as it gives access to the machine-account. Opinions? How do you handle service keytabs and it's rotation? Thank you. Stefan
