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 sssd read, view, and write access to kernel keys
61 with kernel_t type, you must turn on the sssd_access_kernel_keys bool‐
62 ean. Disabled by default.
63
64 setsebool -P sssd_access_kernel_keys 1
65
66
67
68 If you want to allow sssd connect to all unreserved ports, you must
69 turn on the sssd_connect_all_unreserved_ports boolean. Disabled by de‐
70 fault.
71
72 setsebool -P sssd_connect_all_unreserved_ports 1
73
74
75
76 If you want to allow all domains to execute in fips_mode, you must turn
77 on the fips_mode boolean. Enabled by default.
78
79 setsebool -P fips_mode 1
80
81
82
83 If you want to allow Apache to communicate with sssd service via dbus,
84 you must turn on the httpd_dbus_sssd boolean. Disabled by default.
85
86 setsebool -P httpd_dbus_sssd 1
87
88
89
90 If you want to allow system to run with NIS, you must turn on the
91 nis_enabled boolean. Disabled by default.
92
93 setsebool -P nis_enabled 1
94
95
96
98 The SELinux process type sssd_t can manage files labeled with the fol‐
99 lowing file types. The paths listed are the default paths for these
100 file types. Note the processes UID still need to have DAC permissions.

194 SELinux requires files to have an extended attribute to define the file
195 type.

198
199 Policy governs the access confined processes have to these files.
200 SELinux sssd policy is very flexible allowing users to setup their sssd
201 processes in as secure a method as possible.
202
203 EQUIVALENCE DIRECTORIES
204
205
206 sssd policy stores data with multiple different file context types un‐
207 der the /var/lib/sss directory. If you would like to store the data in
208 a different directory you can use the semanage command to create an
209 equivalence mapping. If you wanted to store this data under the /srv
210 directory you would execute the following command:
211
212 semanage fcontext -a -e /var/lib/sss /srv/sss
213 restorecon -R -v /srv/sss
214
215 STANDARD FILE CONTEXT
216
217 SELinux defines the file context types for the sssd, if you wanted to
218 store files with these types in a diffent paths, you need to execute
219 the semanage command to sepecify alternate labeling and then use re‐
220 storecon to put the labels on disk.
221
222 semanage fcontext -a -t sssd_unit_file_t '/srv/mysssd_content(/.*)?'
223 restorecon -R -v /srv/mysssd_content
224
225 Note: SELinux often uses regular expressions to specify labels that
226 match multiple files.
227
228 The following file types are defined for sssd:
229
230
231
232 sssd_conf_t
233
234 - Set files with the sssd_conf_t type, if you want to treat the files
235 as sssd configuration data, usually stored under the /etc directory.
236
237
238
239 sssd_exec_t
240
241 - Set files with the sssd_exec_t type, if you want to transition an ex‐
242 ecutable to the sssd_t domain.
243
244
245 Paths:
246 /usr/sbin/sssd, /usr/libexec/sssd/sssd_ifp,
247 /usr/libexec/sssd/sssd_kcm, /usr/libexec/sssd/sssd_nss,
248 /usr/libexec/sssd/sssd_pac, /usr/libexec/sssd/sssd_pam,
249 /usr/libexec/sssd/sssd_ssh, /usr/libexec/sssd/sssd_sudo,
250 /usr/libexec/sssd/sssd_autofs, /usr/libexec/sssd/sssd_secrets
251
252
253 sssd_initrc_exec_t
254
255 - Set files with the sssd_initrc_exec_t type, if you want to transition
256 an executable to the sssd_initrc_t domain.
257
258
259
260 sssd_public_t
261
262 - Set files with the sssd_public_t type, if you want to treat the files
263 as sssd public data.
264
265
266 Paths:
267 /var/lib/sss/mc(/.*)?, /var/lib/sss/pubconf(/.*)?
268
269
270 sssd_selinux_manager_exec_t
271
272 - Set files with the sssd_selinux_manager_exec_t type, if you want to
273 transition an executable to the sssd_selinux_manager_t domain.
274
275
276
277 sssd_unit_file_t
278
279 - Set files with the sssd_unit_file_t type, if you want to treat the
280 files as sssd unit content.
281
282
283
284 sssd_var_lib_t
285
286 - Set files with the sssd_var_lib_t type, if you want to store the sssd
287 files under the /var/lib directory.
288
289
290
291 sssd_var_log_t
292
293 - Set files with the sssd_var_log_t type, if you want to treat the data
294 as sssd var log data, usually stored under the /var/log directory.
295
296
297
298 sssd_var_run_t
299
300 - Set files with the sssd_var_run_t type, if you want to store the sssd
301 files under the /run or /var/run directory.
302
303
304 Paths:
305 /var/run/sssd.pid, /var/run/secrets.socket,
306 /var/run/.heim_org.h5l.kcm-socket
307
308
309 Note: File context can be temporarily modified with the chcon command.
310 If you want to permanently change the file context you need to use the
311 semanage fcontext command. This will modify the SELinux labeling data‐
312 base. You will need to use restorecon to apply the labels.
313
314
316 semanage fcontext can also be used to manipulate default file context
317 mappings.
318
319 semanage permissive can also be used to manipulate whether or not a
320 process type is permissive.
321
322 semanage module can also be used to enable/disable/install/remove pol‐
323 icy modules.
324
325 semanage boolean can also be used to manipulate the booleans
326
327
328 system-config-selinux is a GUI tool available to customize SELinux pol‐
329 icy settings.
