 "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:


 /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.
.

 "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.


 user_login_process 

This consists of a role:type[:range] entry that represents the user login process context.
