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 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 For example:
18 ps -eZ | grep kadmind_t
20
24 The kadmind_t SELinux type can be entered via the kadmind_exec_t file
25 type.
26 The default entrypoint paths for the kadmind_t domain are the follow‐
28 ing:
29 /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 You can see the context of a process using the -Z option to ps
38 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 The following process types are defined for kadmind:
44 kadmind_t
46 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
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 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 setsebool -P fips_mode 1
65 If you want to allow system to run with NIS, you must turn on the
69 nis_enabled boolean. Disabled by default.
70 setsebool -P nis_enabled 1
72
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.

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