NAME

6       kadmind_selinux  -  Security Enhanced Linux Policy for the kadmind pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

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/(local/)?(kerberos/)?sbin/kadmind, /usr/kerberos/sbin/kadmin.local
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       kadmind  policy  is very flexible allowing users to setup their kadmind
40       processes in as secure a method as possible.
41
42       The following process types are defined for kadmind:
43
44       kadmind_t
45
46       Note: semanage permissive -a kadmind_t can be used to make the  process
47       type  kadmind_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.  kadmind
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run kadmind with the tightest access possi‐
56       ble.

FILE CONTEXTS

238       SELinux requires files to have an extended attribute to define the file
239       type.
240
241       You can see the context of a file using the -Z option to ls
242
243       Policy governs the access  confined  processes  have  to  these  files.
244       SELinux  kadmind  policy is very flexible allowing users to setup their
245       kadmind processes in as secure a method as possible.
246
247       STANDARD FILE CONTEXT
248
249       SELinux defines the file context types for the kadmind, if  you  wanted
250       to store files with these types in a diffent paths, you need to execute
251       the semanage command  to  sepecify  alternate  labeling  and  then  use
252       restorecon to put the labels on disk.
253
254       semanage   fcontext   -a   -t   kadmind_var_run_t  '/srv/mykadmind_con‐
255       tent(/.*)?'
256       restorecon -R -v /srv/mykadmind_content
257
258       Note: SELinux often uses regular expressions  to  specify  labels  that
259       match multiple files.
260
261       The following file types are defined for kadmind:
262
263
264
265       kadmind_exec_t
266
267       -  Set files with the kadmind_exec_t type, if you want to transition an
268       executable to the kadmind_t domain.
269
270
271       Paths:
272            /usr/(local/)?(kerberos/)?sbin/kadmind,    /usr/kerberos/sbin/kad‐
273            min.local
274
275
276       kadmind_log_t
277
278       -  Set files with the kadmind_log_t type, if you want to treat the data
279       as kadmind log data, usually stored under the /var/log directory.
280
281
282
283       kadmind_tmp_t
284
285       - Set files with the kadmind_tmp_t type, if you want to  store  kadmind
286       temporary files in the /tmp directories.
287
288
289       Paths:
290            /var/tmp/kadmin_0, /var/tmp/kiprop_0
291
292
293       kadmind_var_run_t
294
295       -  Set  files with the kadmind_var_run_t type, if you want to store the
296       kadmind files under the /run or /var/run directory.
297
298
299
300       Note: File context can be temporarily modified with the chcon  command.
301       If  you want to permanently change the file context you need to use the
302       semanage fcontext command.  This will modify the SELinux labeling data‐
303       base.  You will need to use restorecon to apply the labels.
304
305

COMMANDS

307       semanage  fcontext  can also be used to manipulate default file context
308       mappings.
309
310       semanage permissive can also be used to manipulate  whether  or  not  a
311       process type is permissive.
312
313       semanage  module can also be used to enable/disable/install/remove pol‐
314       icy modules.
315
316       semanage boolean can also be used to manipulate the booleans
317
318
319       system-config-selinux is a GUI tool available to customize SELinux pol‐
320       icy settings.
