NSS-CACHE-OSLOGIN(8)

NSS-CACHE-OSLOGIN 💖✨

okay bestie, so this is the System Manager's Manual page for nss-cache-oslogin (and its whole other name, libnss_cache_oslogin.so.2) — it's the UNIX implementation for OS Login Users and Groups with local caching. yes that's a lot of words, we'll get there 🫶

🌸 NAME 🌸

nss-cache-oslogin, libnss_cache_oslogin.so.2 — UNIX implementation for OS Login Users and Groups with local caching.

✨ SYNOPSIS ✨

libnss_cache_oslogin.so.2

💅 DESCRIPTION 💅

so nss-cache-oslogin is a plug-in module for the GNU Name Service Switch (NSS) functionality of the GNU C Library (glibc). lowkey iconic of it.

what it does: this module provides UNIX name resolution from a local cache of users and groups that are configured in the Google Cloud OS Login system. it's giving "i know these people, i have them written down." 📝

the services supported by this module are the passwd and group services. those two, and only those two.

to actually use the NSS module, you gotta add cache_oslogin to the appropriate service lines in nsswitch.conf.

and here's the recommendation, listen up: place cache_oslogin after any system provided modules and before the oslogin module, because it is a pass-through cache. order matters bestie, it's a whole vibe. 💖

fr fr, don't skip the ordering bit. it's a pass-through cache, so it wants to sit in that exact spot.

🎀 FILES 🎀
