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 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

MANAGED FILES

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.

FILE CONTEXTS

148       SELinux requires files to have an extended attribute to define the file
149       type.
150
151       You can see the context of a file using the -Z option to ls
152
153       Policy governs the access  confined  processes  have  to  these  files.
154       SELinux  kadmind  policy is very flexible allowing users to setup their
155       kadmind processes in as secure a method as possible.
156
157       STANDARD FILE CONTEXT
158
159       SELinux defines the file context types for the kadmind, if  you  wanted
160       to store files with these types in a diffent paths, you need to execute
161       the semanage command  to  sepecify  alternate  labeling  and  then  use
162       restorecon to put the labels on disk.
163
164       semanage   fcontext   -a   -t   kadmind_var_run_t  '/srv/mykadmind_con‐
165       tent(/.*)?'
166       restorecon -R -v /srv/mykadmind_content
167
168       Note: SELinux often uses regular expressions  to  specify  labels  that
169       match multiple files.
170
171       The following file types are defined for kadmind:
172
173
174
175       kadmind_exec_t
176
177       -  Set files with the kadmind_exec_t type, if you want to transition an
178       executable to the kadmind_t domain.
179
180
181       Paths:
182            /usr/(kerberos/)?sbin/kadmind,     /usr/(kerberos/)?sbin/_kadmind,
183            /usr/kerberos/sbin/kadmin.local
184
185
186       kadmind_log_t
187
188       -  Set files with the kadmind_log_t type, if you want to treat the data
189       as kadmind log data, usually stored under the /var/log directory.
190
191
192
193       kadmind_tmp_t
194
195       - Set files with the kadmind_tmp_t type, if you want to  store  kadmind
196       temporary files in the /tmp directories.
197
198
199       Paths:
200            /var/tmp/kadmin_0, /var/tmp/kiprop_0
201
202
203       kadmind_var_run_t
204
205       -  Set  files with the kadmind_var_run_t type, if you want to store the
206       kadmind files under the /run or /var/run directory.
207
208
209
210       Note: File context can be temporarily modified with the chcon  command.
211       If  you want to permanently change the file context you need to use the
212       semanage fcontext command.  This will modify the SELinux labeling data‐
213       base.  You will need to use restorecon to apply the labels.
214
215

COMMANDS

217       semanage  fcontext  can also be used to manipulate default file context
218       mappings.
219
220       semanage permissive can also be used to manipulate  whether  or  not  a
221       process type is permissive.
222
223       semanage  module can also be used to enable/disable/install/remove pol‐
224       icy modules.
225
226       semanage boolean can also be used to manipulate the booleans
227
228
229       system-config-selinux is a GUI tool available to customize SELinux pol‐
230       icy settings.
