6 saslauthd_selinux - Security Enhanced Linux Policy for the saslauthd
7 processes
8
10 Security-Enhanced Linux secures the saslauthd processes via flexible
11 mandatory access control.
12
13 The saslauthd processes execute with the saslauthd_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep saslauthd_t
20
21
22
24 The saslauthd_t SELinux type can be entered via the saslauthd_exec_t
25 file type.
26
27 The default entrypoint paths for the saslauthd_t domain are the follow‐
28 ing:
29
30 /usr/sbin/saslauthd
31
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 saslauthd policy is very flexible allowing users to setup their saslau‐
40 thd processes in as secure a method as possible.
41
42 The following process types are defined for saslauthd:
43
44 saslauthd_t
45
46 Note: semanage permissive -a saslauthd_t can be used to make the
47 process type saslauthd_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. saslau‐
54 thd policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run saslauthd with the tightest access
56 possible.
57
58
59
60 If you want to allow sasl to read shadow, you must turn on the saslau‐
61 thd_read_shadow boolean. Disabled by default.
62
63 setsebool -P saslauthd_read_shadow 1
64
65
66
67 If you want to dontaudit all daemons scheduling requests (setsched,
68 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
69 Enabled by default.
70
71 setsebool -P daemons_dontaudit_scheduling 1
72
73
74
75 If you want to allow all domains to execute in fips_mode, you must turn
76 on the fips_mode boolean. Enabled by default.
77
78 setsebool -P fips_mode 1
79
80
81
82 If you want to allow confined applications to run with kerberos, you
83 must turn on the kerberos_enabled boolean. Enabled by default.
84
85 setsebool -P kerberos_enabled 1
86
87
88
89 If you want to allow system to run with NIS, you must turn on the
90 nis_enabled boolean. Disabled by default.
91
92 setsebool -P nis_enabled 1
93
94
95
97 The SELinux process type saslauthd_t can manage files labeled with the
98 following file types. The paths listed are the default paths for these
99 file types. Note the processes UID still need to have DAC permissions.

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 saslauthd policy is very flexible allowing users to setup their
180 saslauthd processes in as secure a method as possible.
181
182 STANDARD FILE CONTEXT
183
184 SELinux defines the file context types for the saslauthd, 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 saslauthd_exec_t '/srv/saslauthd/content(/.*)?'
190 restorecon -R -v /srv/mysaslauthd_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 saslauthd:
196
197
198
199 saslauthd_exec_t
200
201 - Set files with the saslauthd_exec_t type, if you want to transition
202 an executable to the saslauthd_t domain.
203
204
205
206 saslauthd_initrc_exec_t
207
208 - Set files with the saslauthd_initrc_exec_t type, if you want to tran‐
209 sition an executable to the saslauthd_initrc_t domain.
210
211
212
213 saslauthd_keytab_t
214
215 - Set files with the saslauthd_keytab_t type, if you want to treat the
216 files as kerberos keytab files.
217
218
219
220 saslauthd_var_run_t
221
222 - Set files with the saslauthd_var_run_t type, if you want to store the
223 saslauthd files under the /run or /var/run directory.
224
225
226 Paths:
227 /var/lib/sasl2(/.*)?, /var/run/saslauthd(/.*)?
228
229
230 Note: File context can be temporarily modified with the chcon command.
231 If you want to permanently change the file context you need to use the
232 semanage fcontext command. This will modify the SELinux labeling data‐
233 base. You will need to use restorecon to apply the labels.
234
235
237 semanage fcontext can also be used to manipulate default file context
238 mappings.
239
240 semanage permissive can also be used to manipulate whether or not a
241 process type is permissive.
242
243 semanage module can also be used to enable/disable/install/remove pol‐
244 icy modules.
245
246 semanage boolean can also be used to manipulate the booleans
247
248
249 system-config-selinux is a GUI tool available to customize SELinux pol‐
250 icy settings.
