6 sssd_selinux - Security Enhanced Linux Policy for the sssd processes
7
9 Security-Enhanced Linux secures the sssd processes via flexible manda‐
10 tory access control.
11
12 The sssd processes execute with the sssd_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep sssd_t
19
20
21
23 The sssd_t SELinux type can be entered via the sssd_exec_t file type.
24
25 The default entrypoint paths for the sssd_t domain are the following:
26
27 /usr/sbin/sssd, /usr/libexec/sssd/sssd_ifp, /usr/libexec/sssd/sssd_kcm,
28 /usr/libexec/sssd/sssd_nss, /usr/libexec/sssd/sssd_pac,
29 /usr/libexec/sssd/sssd_pam, /usr/libexec/sssd/sssd_ssh,
30 /usr/libexec/sssd/sssd_sudo, /usr/libexec/sssd/sssd_autofs,
31 /usr/libexec/sssd/sssd_secrets
32
34 SELinux defines process types (domains) for each process running on the
35 system
36
37 You can see the context of a process using the -Z option to ps
38
39 Policy governs the access confined processes have to files. SELinux
40 sssd policy is very flexible allowing users to setup their sssd pro‐
41 cesses in as secure a method as possible.
42
43 The following process types are defined for sssd:
44
45 sssd_t, sssd_selinux_manager_t
46
47 Note: semanage permissive -a sssd_t can be used to make the process
48 type sssd_t permissive. SELinux does not deny access to permissive
49 process types, but the AVC (SELinux denials) messages are still gener‐
50 ated.
51
52
54 SELinux policy is customizable based on least access required. sssd
55 policy is extremely flexible and has several booleans that allow you to
56 manipulate the policy and run sssd with the tightest access possible.
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 Apache to communicate with sssd service via dbus,
76 you must turn on the httpd_dbus_sssd boolean. Disabled by default.
77
78 setsebool -P httpd_dbus_sssd 1
79
80
81
82 If you want to allow confined applications to run with kerberos, you
83 must turn on the kerberos_enabled boolean. Enabled by default.
84
85 setsebool -P kerberos_enabled 1
86
87
88
89 If you want to allow system to run with NIS, you must turn on the
90 nis_enabled boolean. Disabled by default.
91
92 setsebool -P nis_enabled 1
93
94
95
96 If you want to allow confined applications to use nscd shared memory,
97 you must turn on the nscd_use_shm boolean. Disabled by default.
98
99 setsebool -P nscd_use_shm 1
100
101
102
104 The SELinux process type sssd_t can manage files labeled with the fol‐
105 lowing file types. The paths listed are the default paths for these
106 file types. Note the processes UID still need to have DAC permissions.

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 sssd policy is very flexible allowing users to setup their sssd
239 processes in as secure a method as possible.
240
241 EQUIVALENCE DIRECTORIES
242
243
244 sssd policy stores data with multiple different file context types
245 under the /var/lib/sss directory. If you would like to store the data
246 in a different directory you can use the semanage command to create an
247 equivalence mapping. If you wanted to store this data under the /srv
248 dirctory you would execute the following command:
249
250 semanage fcontext -a -e /var/lib/sss /srv/sss
251 restorecon -R -v /srv/sss
252
253 STANDARD FILE CONTEXT
254
255 SELinux defines the file context types for the sssd, if you wanted to
256 store files with these types in a diffent paths, you need to execute
257 the semanage command to sepecify alternate labeling and then use
258 restorecon to put the labels on disk.
259
260 semanage fcontext -a -t sssd_unit_file_t '/srv/mysssd_content(/.*)?'
261 restorecon -R -v /srv/mysssd_content
262
263 Note: SELinux often uses regular expressions to specify labels that
264 match multiple files.
265
266 The following file types are defined for sssd:
267
268
269
270 sssd_conf_t
271
272 - Set files with the sssd_conf_t type, if you want to treat the files
273 as sssd configuration data, usually stored under the /etc directory.
274
275
276
277 sssd_exec_t
278
279 - Set files with the sssd_exec_t type, if you want to transition an
280 executable to the sssd_t domain.
281
282
283 Paths:
284 /usr/sbin/sssd, /usr/libexec/sssd/sssd_ifp,
285 /usr/libexec/sssd/sssd_kcm, /usr/libexec/sssd/sssd_nss,
286 /usr/libexec/sssd/sssd_pac, /usr/libexec/sssd/sssd_pam,
287 /usr/libexec/sssd/sssd_ssh, /usr/libexec/sssd/sssd_sudo,
288 /usr/libexec/sssd/sssd_autofs, /usr/libexec/sssd/sssd_secrets
289
290
291 sssd_initrc_exec_t
292
293 - Set files with the sssd_initrc_exec_t type, if you want to transition
294 an executable to the sssd_initrc_t domain.
295
296
297
298 sssd_public_t
299
300 - Set files with the sssd_public_t type, if you want to treat the files
301 as sssd public data.
302
303
304 Paths:
305 /var/lib/sss/mc(/.*)?, /var/lib/sss/pubconf(/.*)?
306
307
308 sssd_selinux_manager_exec_t
309
310 - Set files with the sssd_selinux_manager_exec_t type, if you want to
311 transition an executable to the sssd_selinux_manager_t domain.
312
313
314
315 sssd_unit_file_t
316
317 - Set files with the sssd_unit_file_t type, if you want to treat the
318 files as sssd unit content.
319
320
321
322 sssd_var_lib_t
323
324 - Set files with the sssd_var_lib_t type, if you want to store the sssd
325 files under the /var/lib directory.
326
327
328
329 sssd_var_log_t
330
331 - Set files with the sssd_var_log_t type, if you want to treat the data
332 as sssd var log data, usually stored under the /var/log directory.
333
334
335
336 sssd_var_run_t
337
338 - Set files with the sssd_var_run_t type, if you want to store the sssd
339 files under the /run or /var/run directory.
340
341
342 Paths:
343 /var/run/sssd.pid, /var/run/secrets.socket,
344 /var/run/.heim_org.h5l.kcm-socket
345
346
347 Note: File context can be temporarily modified with the chcon command.
348 If you want to permanently change the file context you need to use the
349 semanage fcontext command. This will modify the SELinux labeling data‐
350 base. You will need to use restorecon to apply the labels.
351
352
354 semanage fcontext can also be used to manipulate default file context
355 mappings.
356
357 semanage permissive can also be used to manipulate whether or not a
358 process type is permissive.
359
360 semanage module can also be used to enable/disable/install/remove pol‐
361 icy modules.
362
363 semanage boolean can also be used to manipulate the booleans
364
365
366 system-config-selinux is a GUI tool available to customize SELinux pol‐
367 icy settings.
