NAME

user_contexts - The SELinux user contexts configuration files

DESCRIPTION

These optional user context configuration files contain entries that allow SELinux-aware login applications such as PAM(8) (running in their own process context), to determine the context that a users login session should run under.

SELinux-aware login applications generally use one or more of the following libselinux functions that read these files from the active policy path:

There can be one file for each SELinux user configured on the system. The file path is formed using the path returned by selinux_user_contexts_path(3) for the active policy, with the SELinux user name appended, for example:

Where {SELINUXTYPE} is the entry from the selinux configuration file config (see selinux_config(5)).

These files contain context information as described in the FILE FORMAT section.

FILE FORMAT

Each line in the user context configuration file consists of the following:
