6 kadmind_selinux - Security Enhanced Linux Policy for the kadmind pro‐
7 cesses
8
10 Security-Enhanced Linux secures the kadmind processes via flexible
11 mandatory access control.
12
13 The kadmind processes execute with the kadmind_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 kadmind_t
20
21
22
24 The kadmind_t SELinux type can be entered via the kadmind_exec_t file
25 type.
26
27 The default entrypoint paths for the kadmind_t domain are the follow‐
28 ing:
29
30 /usr/(kerberos/)?sbin/kadmind, /usr/(kerberos/)?sbin/_kadmind,
31 /usr/kerberos/sbin/kadmin.local
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 kadmind policy is very flexible allowing users to setup their kadmind
41 processes in as secure a method as possible.
42
43 The following process types are defined for kadmind:
44
45 kadmind_t
46
47 Note: semanage permissive -a kadmind_t can be used to make the process
48 type kadmind_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. kadmind
55 policy is extremely flexible and has several booleans that allow you to
56 manipulate the policy and run kadmind with the tightest access possi‐
57 ble.
58
59
60
61 If you want to allow all domains to execute in fips_mode, you must turn
62 on the fips_mode boolean. Enabled by default.
63
64 setsebool -P fips_mode 1
65
66
67
68 If you want to allow system to run with NIS, you must turn on the
69 nis_enabled boolean. Disabled by default.
70
71 setsebool -P nis_enabled 1
72
73
74
76 The SELinux process type kadmind_t can manage files labeled with the
77 following file types. The paths listed are the default paths for these
78 file types. Note the processes UID still need to have DAC permissions.

165 SELinux requires files to have an extended attribute to define the file
166 type.
167
168 You can see the context of a file using the -Z option to ls
169
170 Policy governs the access confined processes have to these files.
171 SELinux kadmind policy is very flexible allowing users to setup their
172 kadmind processes in as secure a method as possible.
173
174 STANDARD FILE CONTEXT
175
176 SELinux defines the file context types for the kadmind, if you wanted
177 to store files with these types in a diffent paths, you need to execute
178 the semanage command to specify alternate labeling and then use re‐
179 storecon to put the labels on disk.
180
181 semanage fcontext -a -t kadmind_var_run_t '/srv/mykadmind_con‐
182 tent(/.*)?'
183 restorecon -R -v /srv/mykadmind_content
184
185 Note: SELinux often uses regular expressions to specify labels that
186 match multiple files.
187
188 The following file types are defined for kadmind:
189
190
191
192 kadmind_exec_t
193
194 - Set files with the kadmind_exec_t type, if you want to transition an
195 executable to the kadmind_t domain.
196
197
198 Paths:
199 /usr/(kerberos/)?sbin/kadmind, /usr/(kerberos/)?sbin/_kadmind,
200 /usr/kerberos/sbin/kadmin.local
201
202
203 kadmind_log_t
204
205 - Set files with the kadmind_log_t type, if you want to treat the data
206 as kadmind log data, usually stored under the /var/log directory.
207
208
209
210 kadmind_tmp_t
211
212 - Set files with the kadmind_tmp_t type, if you want to store kadmind
213 temporary files in the /tmp directories.
214
215
216 Paths:
217 /var/tmp/kadmin_0, /var/tmp/kiprop_0
218
219
220 kadmind_var_run_t
221
222 - Set files with the kadmind_var_run_t type, if you want to store the
223 kadmind files under the /run or /var/run directory.
224
225
226
227 Note: File context can be temporarily modified with the chcon command.
228 If you want to permanently change the file context you need to use the
229 semanage fcontext command. This will modify the SELinux labeling data‐
230 base. You will need to use restorecon to apply the labels.
231
232
234 semanage fcontext can also be used to manipulate default file context
235 mappings.
236
237 semanage permissive can also be used to manipulate whether or not a
238 process type is permissive.
239
240 semanage module can also be used to enable/disable/install/remove pol‐
241 icy modules.
242
243 semanage boolean can also be used to manipulate the booleans
244
245
246 system-config-selinux is a GUI tool available to customize SELinux pol‐
247 icy settings.
