rlm_unix(5)

💖 NAME 💖

okay bestie, meet rlm_unix — the FreeRADIUS Module and the star of this rlm_unix(5) page. main character energy fr fr 💅

---

🦋 DESCRIPTION 🦋

So the rlm_unix module reads crypt(3) passwords from the system password file and lets the server use them for authentication. It also gives FreeRADIUS an interface into a radwtmp file — the one used by radlast — when it's added to the accounting section. slay ✨

This module should be listed in the "authenticate" section. Please see the default radiusd.conf shipped with the server for an example of the correct usage of this module. iykyk 🫶

As of FreeRADIUS 1.1.0, the module no longer reads, or caches, /etc/passwd, /etc/shadow, or /etc/group. If you wish to cache those files, see rlm_passwd. Most, if not all, configurations should not need those files to be cached. no cap, that's the vibe now 🌸

The main configuration items to be aware of are:

• radwtmp — the path to the system wtmp file that's used for keeping the database of online users as read by the radlast program. lowkey important 👑
