Security-Enhanced Linux secures the systemd_logind processes via flexible mandatory access control.
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd serve for the systemd_logind_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the systemd_logind_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux systemd_logind policy is very flexible allowing users to setup their systemd_logind processes in as secure a method as possible.
The following file types are defined for systemd_logind:
systemd_logind_exec_t
- Set files with the systemd_logind_exec_t type, if you want to transition an executable to the systemd_logind_t domain.
systemd_logind_inhibit_var_run_t
- Set files with the systemd_logind_inhibit_var_run_t type, if you want to store the systemd logind inhibit files under the /run directory.
systemd_logind_sessions_t
- Set files with the systemd_logind_sessions_t type, if you want to treat the files as systemd logind sessions data.
systemd_logind_var_run_t
- Set files with the systemd_logind_var_run_t type, if you want to store the systemd logind files under the /run directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux systemd_logind policy is very flexible allowing users to setup their systemd_logind processes in as secure a method as possible.
The following process types are defined for systemd_logind:
systemd_logind_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.
The SELinux user type systemd_logind_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
