The selinux user contexts configuration files
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:
get_ordered_context_list_with_level(3)
get_default_context_with_level(3)
get_default_context_with_role(3)
get_default_context_with_rolelevel(3)
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:
/etc/selinux/{SELINUXTYPE}/contexts/users/unconfined_u
/etc/selinux/{SELINUXTYPE}/contexts/users/xguest_u
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.
Each line in the user context configuration file consists of the following:
login_process user_login_process
Where:
login_process
This consists of a role:type[:range] entry that represents the login process context.
user_login_process
This consists of a role:type[:range] entry that represents the user login process context.
