Security-Enhanced Linux secures the policykit 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 policykit_grant_t, policykit_auth_t, policykit_t, policykit_resolve_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 policykit_grant_t, policykit_auth_t, policykit_t, policykit_resolve_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 policykit policy is very flexible allowing users to setup their policykit processes in as secure a method as possible.
The following file types are defined for policykit:
policykit_auth_exec_t
- Set files with the policykit_auth_exec_t type, if you want to transition an executable to the policykit_auth_t domain.
policykit_exec_t
- Set files with the policykit_exec_t type, if you want to transition an executable to the policykit_t domain.
policykit_grant_exec_t
- Set files with the policykit_grant_exec_t type, if you want to transition an executable to the policykit_grant_t domain.
policykit_reload_t
- Set files with the policykit_reload_t type, if you want to treat the files as policykit reload data.
policykit_resolve_exec_t
- Set files with the policykit_resolve_exec_t type, if you want to transition an executable to the policykit_resolve_t domain.
policykit_tmp_t
- Set files with the policykit_tmp_t type, if you want to store policykit temporary files in the /tmp directories.
policykit_var_lib_t
- Set files with the policykit_var_lib_t type, if you want to store the policykit files under the /var/lib directory.
policykit_var_run_t
- Set files with the policykit_var_run_t type, if you want to store the policykit 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 policykit policy is very flexible allowing users to setup their policykit processes in as secure a method as possible.
The following process types are defined for policykit:
policykit_grant_t, policykit_auth_t, policykit_t, policykit_resolve_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are
