winbind_selinux(8) winbind SELinux Policy documentation winbind_selinux(8)NAMEwinbind_selinux - Security Enhanced Linux Policy for the winbind pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the winbind processes via flexible
mandatory access control.
BOOLEANS
SELinux policy is customizable based on least access required. winbind
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run winbind with the tightest access possi‐
ble.
If you want to allow Apache to use mod_auth_ntlm_winbin, you must turn
on the allow_httpd_mod_auth_ntlm_winbind boolean.
setsebool -P allow_httpd_mod_auth_ntlm_winbind 1
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the win‐
bind_helper_t, winbind_t, you must turn on the authlogin_nss‐
witch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
winbind_helper_t, winbind_t, you must turn on the allow_kerberos bool‐
ean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the winbind_helper_t,
winbind_t, you must turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files.
SELinux winbind policy is very flexible allowing users to setup their
winbind processes in as secure a method as possible.
The following file types are defined for winbind:
winbind_exec_t
- Set files with the winbind_exec_t type, if you want to transition an
executable to the winbind_t domain.
winbind_helper_exec_t
- Set files with the winbind_helper_exec_t type, if you want to transi‐
tion an executable to the winbind_helper_t domain.
winbind_log_t
- Set files with the winbind_log_t type, if you want to treat the data
as winbind log data, usually stored under the /var/log directory.
winbind_var_run_t
- Set files with the winbind_var_run_t type, if you want to store the
winbind files under the /run directory.
Paths:
/var/cache/samba/winbindd_privileged(/.*)?, /var/lib/samba/win‐
bindd_privileged(/.*)?, /var/run/winbindd(/.*)?,
/var/run/samba/winbindd(/.*)?
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux
winbind policy is very flexible allowing users to setup their winbind
processes in as secure a method as possible.
The following process types are defined for winbind:
winbind_helper_t, winbind_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.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
