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/(kerberos/)?sbin/kadmind,          /usr/(kerberos/)?sbin/_kadmind,
31       /usr/kerberos/sbin/kadmin.local
32

PROCESS TYPES

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

BOOLEANS

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  dontaudit all daemons scheduling requests (setsched,
62       sys_nice), you must turn on the  daemons_dontaudit_scheduling  boolean.
63       Enabled by default.
64
65       setsebool -P daemons_dontaudit_scheduling 1
66
67
68
69       If you want to allow all domains to execute in fips_mode, you must turn
70       on the fips_mode boolean. Enabled by default.
71
72       setsebool -P fips_mode 1
73
74
75
76       If you want to allow system to run with  NIS,  you  must  turn  on  the
77       nis_enabled boolean. Disabled by default.
78
79       setsebool -P nis_enabled 1

MANAGED FILES

84       The  SELinux  process  type kadmind_t can manage files labeled with the
85       following file types.  The paths listed are the default paths for these
86       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

173       SELinux requires files to have an extended attribute to define the file
174       type.
175
176       You can see the context of a file using the -Z option to ls
177
178       Policy governs the access  confined  processes  have  to  these  files.
179       SELinux  kadmind  policy is very flexible allowing users to setup their
180       kadmind processes in as secure a method as possible.
181
182       STANDARD FILE CONTEXT
183
184       SELinux defines the file context types for the kadmind, if  you  wanted
185       to  store files with these types in a different paths, you need to exe‐
186       cute the semanage command to specify alternate labeling  and  then  use
187       restorecon to put the labels on disk.
188
189       semanage fcontext -a -t kadmind_exec_t '/srv/kadmind/content(/.*)?'
190       restorecon -R -v /srv/mykadmind_content
191
192       Note:  SELinux  often  uses  regular expressions to specify labels that
193       match multiple files.
194
195       The following file types are defined for kadmind:
196
197
198
199       kadmind_exec_t
200
201       - Set files with the kadmind_exec_t type, if you want to transition  an
202       executable to the kadmind_t domain.
203
204
205       Paths:
206            /usr/(kerberos/)?sbin/kadmind,     /usr/(kerberos/)?sbin/_kadmind,
207            /usr/kerberos/sbin/kadmin.local
208
209
210       kadmind_log_t
211
212       - Set files with the kadmind_log_t type, if you want to treat the  data
213       as kadmind log data, usually stored under the /var/log directory.
214
215
216
217       kadmind_tmp_t
218
219       -  Set  files with the kadmind_tmp_t type, if you want to store kadmind
220       temporary files in the /tmp directories.
221
222
223       Paths:
224            /var/tmp/kadmin_0, /var/tmp/kiprop_0
225
226
227       kadmind_var_run_t
228
229       - Set files with the kadmind_var_run_t type, if you want to  store  the
230       kadmind files under the /run or /var/run directory.
231
232
233
234       Note:  File context can be temporarily modified with the chcon command.
235       If you want to permanently change the file context you need to use  the
236       semanage fcontext command.  This will modify the SELinux labeling data‐
237       base.  You will need to use restorecon to apply the labels.
238
239

COMMANDS

241       semanage fcontext can also be used to manipulate default  file  context
242       mappings.
243
244       semanage  permissive  can  also  be used to manipulate whether or not a
245       process type is permissive.
246
247       semanage module can also be used to enable/disable/install/remove  pol‐
248       icy modules.
249
250       semanage boolean can also be used to manipulate the booleans
251
252
253       system-config-selinux is a GUI tool available to customize SELinux pol‐
254       icy settings.
