"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:
get_default_context (3)
get_ordered_context_list (3)
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)
query_user_context (3)
manual_user_enter_context (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:
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:
login_process user_login_process
Where:
login_process
This consists of a role:type[:range] entry that represents the login process context.
This consists of a role:type[:range] entry that represents the user login process context.
