Got some progress with protocol transition in OpenSSH: if you login with any authentication mechanism that does not lead to creation of Kerberos tickets, now you can configure your server to generate one on the user's behalf. This uses Services For User (S4U) extensions available in Active […]

#FreeIPA at #FOSDEM :)

We are almost ready with #FreeIPA #SSSD #Keycloak stand at #FOSDEM. Come to visit us at building K!

About to leave to Brussels for #CentOSConnect and #FOSDEM. We will have a #FreeIPA / #SSSD / #Keycloak stand on Saturday (at building K level 1 group C) and Identity and Access Management devroom (H.2214).

Come to see and discuss!

2) 🇨🇿 The Czech National Film Archive uses a similat setup to #EU_OS: #AlmaLinux #bootc with #freeIPA for some of their staff. Now Czechia is on the map! nfa.cz/en

I’ve documented a clean, native way to join FreeBSD 15 to a FreeIPA realm. Pure Kerberos (GSSAPI). Lightweight LDAP (nslcd). No local user management.

Keep your base system sane.

Past week was busy. We released #FreeIPA 4.12.5 with the fix for CVE-2025-7493. I think we ended up doing 13 downstream releases (RHEL+Fedora) and anticipate several weeks of busy freeipa-users@ traffic.

New FreeIPA Web UI support was merged upstream but building it on the […]

#YesterdayAtWork:

- #FreeIPA and #Samba 4.23 interop fixes pushed to #Fedora 43 updates stable. Not sure they are part of the Fedora 43 beta iso image, though.

#YesterdayAtWork:
- the new #Samba 4.23 release candidates found a bug I had in #FreeIPA for a decade. MS-DRSR spec forces version of ForestTrustInfo structure to be set to 1 (the only supported type) and Samba started enforcing it. FreeIPA saved the structure with a default (0) version number […]
