NAME

6       winbind_selinux  -  Security Enhanced Linux Policy for the winbind pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  winbind  processes  via  flexible
11       mandatory access control.
12
13       The  winbind processes execute with the winbind_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep winbind_t
20
21
22

ENTRYPOINTS

24       The  winbind_t  SELinux type can be entered via the winbind_exec_t file
25       type.
26
27       The default entrypoint paths for the winbind_t domain are  the  follow‐
28       ing:
29
30       /usr/sbin/winbindd
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       winbind  policy  is very flexible allowing users to setup their winbind
40       processes in as secure a method as possible.
41
42       The following process types are defined for winbind:
43
44       winbind_t, winbind_helper_t
45
46       Note: semanage permissive -a winbind_t can be used to make the  process
47       type  winbind_t  permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux policy is customizable based on least access required.  winbind
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run winbind with the tightest access possi‐
56       ble.
57
58
59
60       If you want to allow users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       If you want to allow all domains to execute in fips_mode, you must turn
69       on the fips_mode boolean. Enabled by default.
70
71       setsebool -P fips_mode 1
72
73
74
75       If  you  want  to allow confined applications to run with kerberos, you
76       must turn on the kerberos_enabled boolean. Enabled by default.
77
78       setsebool -P kerberos_enabled 1
79
80
81
82       If you want to allow system to run with  NIS,  you  must  turn  on  the
83       nis_enabled boolean. Disabled by default.
84
85       setsebool -P nis_enabled 1
86
87
88
89       If  you  want to allow confined applications to use nscd shared memory,
90       you must turn on the nscd_use_shm boolean. Disabled by default.
91
92       setsebool -P nscd_use_shm 1
93

MANAGED FILES

97       The SELinux process type winbind_t can manage files  labeled  with  the
98       following file types.  The paths listed are the default paths for these
99       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

232       SELinux requires files to have an extended attribute to define the file
233       type.
234
235       You can see the context of a file using the -Z option to ls
236
237       Policy  governs  the  access  confined  processes  have to these files.
238       SELinux winbind policy is very flexible allowing users to  setup  their
239       winbind processes in as secure a method as possible.
240
241       STANDARD FILE CONTEXT
242
243       SELinux  defines  the file context types for the winbind, if you wanted
244       to store files with these types in a diffent paths, you need to execute
245       the  semanage  command  to  sepecify  alternate  labeling  and then use
246       restorecon to put the labels on disk.
247
248       semanage  fcontext   -a   -t   winbind_var_run_t   '/srv/mywinbind_con‐
249       tent(/.*)?'
250       restorecon -R -v /srv/mywinbind_content
251
252       Note:  SELinux  often  uses  regular expressions to specify labels that
253       match multiple files.
254
255       The following file types are defined for winbind:
256
257
258
259       winbind_exec_t
260
261       - Set files with the winbind_exec_t type, if you want to transition  an
262       executable to the winbind_t domain.
263
264
265
266       winbind_helper_exec_t
267
268       - Set files with the winbind_helper_exec_t type, if you want to transi‐
269       tion an executable to the winbind_helper_t domain.
270
271
272
273       winbind_log_t
274
275       - Set files with the winbind_log_t type, if you want to treat the  data
276       as winbind log data, usually stored under the /var/log directory.
277
278
279
280       winbind_var_run_t
281
282       -  Set  files with the winbind_var_run_t type, if you want to store the
283       winbind files under the /run or /var/run directory.
284
285
286       Paths:
287            /var/run/winbindd(/.*)?,            /var/run/samba/winbindd(/.*)?,
288            /var/lib/samba/winbindd_privileged(/.*)?,    /var/cache/samba/win‐
289            bindd_privileged(/.*)?
290
291
292       Note: File context can be temporarily modified with the chcon  command.
293       If  you want to permanently change the file context you need to use the
294       semanage fcontext command.  This will modify the SELinux labeling data‐
295       base.  You will need to use restorecon to apply the labels.
296
297

COMMANDS

299       semanage  fcontext  can also be used to manipulate default file context
300       mappings.
301
302       semanage permissive can also be used to manipulate  whether  or  not  a
303       process type is permissive.
304
305       semanage  module can also be used to enable/disable/install/remove pol‐
306       icy modules.
307
308       semanage boolean can also be used to manipulate the booleans
309
310
311       system-config-selinux is a GUI tool available to customize SELinux pol‐
312       icy settings.
