user_contexts(5)                                SELinux configuration                                user_contexts(5)



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.

       xguest_r:xguest_t:s0          xguest_r:xguest_t:s0
