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 users to resolve user passwd entries directly from
68 ldap rather then using a sssd server, you must turn on the authlo‐
69 gin_nsswitch_use_ldap boolean. Disabled by default.
70
71 setsebool -P authlogin_nsswitch_use_ldap 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
96 If you want to allow confined applications to use nscd shared memory,
97 you must turn on the nscd_use_shm boolean. Disabled by default.
98
99 setsebool -P nscd_use_shm 1
100
101
102
104 The SELinux process type saslauthd_t can manage files labeled with the
105 following file types. The paths listed are the default paths for these
106 file types. Note the processes UID still need to have DAC permissions.

178 SELinux requires files to have an extended attribute to define the file
179 type.
180
181 You can see the context of a file using the -Z option to ls
182
183 Policy governs the access confined processes have to these files.
184 SELinux saslauthd policy is very flexible allowing users to setup their
185 saslauthd processes in as secure a method as possible.
186
187 STANDARD FILE CONTEXT
188
189 SELinux defines the file context types for the saslauthd, if you wanted
190 to store files with these types in a diffent paths, you need to execute
191 the semanage command to sepecify alternate labeling and then use
192 restorecon to put the labels on disk.
193
194 semanage fcontext -a -t saslauthd_var_run_t '/srv/mysaslauthd_con‐
195 tent(/.*)?'
196 restorecon -R -v /srv/mysaslauthd_content
197
198 Note: SELinux often uses regular expressions to specify labels that
199 match multiple files.
200
201 The following file types are defined for saslauthd:
202
203
204
205 saslauthd_exec_t
206
207 - Set files with the saslauthd_exec_t type, if you want to transition
208 an executable to the saslauthd_t domain.
209
210
211
212 saslauthd_initrc_exec_t
213
214 - Set files with the saslauthd_initrc_exec_t type, if you want to tran‐
215 sition an executable to the saslauthd_initrc_t domain.
216
217
218
219 saslauthd_keytab_t
220
221 - Set files with the saslauthd_keytab_t type, if you want to treat the
222 files as kerberos keytab files.
223
224
225
226 saslauthd_var_run_t
227
228 - Set files with the saslauthd_var_run_t type, if you want to store the
229 saslauthd files under the /run or /var/run directory.
230
231
232 Paths:
233 /var/lib/sasl2(/.*)?, /var/run/saslauthd(/.*)?
234
235
236 Note: File context can be temporarily modified with the chcon command.
237 If you want to permanently change the file context you need to use the
238 semanage fcontext command. This will modify the SELinux labeling data‐
239 base. You will need to use restorecon to apply the labels.
240
241
243 semanage fcontext can also be used to manipulate default file context
244 mappings.
245
246 semanage permissive can also be used to manipulate whether or not a
247 process type is permissive.
248
249 semanage module can also be used to enable/disable/install/remove pol‐
250 icy modules.
251
252 semanage boolean can also be used to manipulate the booleans
253
254
255 system-config-selinux is a GUI tool available to customize SELinux pol‐
256 icy settings.
