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 allow all domains to execute in fips_mode, you must turn
68 on the fips_mode boolean. Enabled by default.
69
70 setsebool -P fips_mode 1
71
72
73
74 If you want to allow confined applications to run with kerberos, you
75 must turn on the kerberos_enabled boolean. Enabled by default.
76
77 setsebool -P kerberos_enabled 1
78
79
80
81 If you want to allow system to run with NIS, you must turn on the
82 nis_enabled boolean. Disabled by default.
83
84 setsebool -P nis_enabled 1
85
86
87
89 The SELinux process type saslauthd_t can manage files labeled with the
90 following file types. The paths listed are the default paths for these
91 file types. Note the processes UID still need to have DAC permissions.

165 SELinux requires files to have an extended attribute to define the file
166 type.
167
168 You can see the context of a file using the -Z option to ls
169
170 Policy governs the access confined processes have to these files.
171 SELinux saslauthd policy is very flexible allowing users to setup their
172 saslauthd processes in as secure a method as possible.
173
174 STANDARD FILE CONTEXT
175
176 SELinux defines the file context types for the saslauthd, if you wanted
177 to store files with these types in a diffent paths, you need to execute
178 the semanage command to specify alternate labeling and then use re‐
179 storecon to put the labels on disk.
180
181 semanage fcontext -a -t saslauthd_var_run_t '/srv/mysaslauthd_con‐
182 tent(/.*)?'
183 restorecon -R -v /srv/mysaslauthd_content
184
185 Note: SELinux often uses regular expressions to specify labels that
186 match multiple files.
187
188 The following file types are defined for saslauthd:
189
190
191
192 saslauthd_exec_t
193
194 - Set files with the saslauthd_exec_t type, if you want to transition
195 an executable to the saslauthd_t domain.
196
197
198
199 saslauthd_initrc_exec_t
200
201 - Set files with the saslauthd_initrc_exec_t type, if you want to tran‐
202 sition an executable to the saslauthd_initrc_t domain.
203
204
205
206 saslauthd_keytab_t
207
208 - Set files with the saslauthd_keytab_t type, if you want to treat the
209 files as kerberos keytab files.
210
211
212
213 saslauthd_var_run_t
214
215 - Set files with the saslauthd_var_run_t type, if you want to store the
216 saslauthd files under the /run or /var/run directory.
217
218
219 Paths:
220 /var/lib/sasl2(/.*)?, /var/run/saslauthd(/.*)?
221
222
223 Note: File context can be temporarily modified with the chcon command.
224 If you want to permanently change the file context you need to use the
225 semanage fcontext command. This will modify the SELinux labeling data‐
226 base. You will need to use restorecon to apply the labels.
227
228
230 semanage fcontext can also be used to manipulate default file context
231 mappings.
232
233 semanage permissive can also be used to manipulate whether or not a
234 process type is permissive.
235
236 semanage module can also be used to enable/disable/install/remove pol‐
237 icy modules.
238
239 semanage boolean can also be used to manipulate the booleans
240
241
242 system-config-selinux is a GUI tool available to customize SELinux pol‐
243 icy settings.
