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 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 For example:
18 ps -eZ | grep saslauthd_t
20
24 The saslauthd_t SELinux type can be entered via the saslauthd_exec_t
25 file type.
26 The default entrypoint paths for the saslauthd_t domain are the follow‐
28 ing:
29 /usr/sbin/saslauthd
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for saslauthd:
43 saslauthd_t
45 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
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 If you want to allow sasl to read shadow, you must turn on the saslau‐
61 thd_read_shadow boolean. Disabled by default.
62 setsebool -P saslauthd_read_shadow 1
64 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 setsebool -P fips_mode 1
71 If you want to allow confined applications to run with kerberos, you
75 must turn on the kerberos_enabled boolean. Disabled by default.
76 setsebool -P kerberos_enabled 1
78 If you want to allow system to run with NIS, you must turn on the
82 nis_enabled boolean. Disabled by default.
83 setsebool -P nis_enabled 1
85
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.

150 SELinux requires files to have an extended attribute to define the file
151 type.
152 You can see the context of a file using the -Z option to ls
154 Policy governs the access confined processes have to these files.
156 SELinux saslauthd policy is very flexible allowing users to setup their
157 saslauthd processes in as secure a method as possible.
158 STANDARD FILE CONTEXT
160 SELinux defines the file context types for the saslauthd, if you wanted
162 to store files with these types in a diffent paths, you need to execute
163 the semanage command to sepecify alternate labeling and then use
164 restorecon to put the labels on disk.
165 semanage fcontext -a -t saslauthd_var_run_t '/srv/mysaslauthd_con‐
167 tent(/.*)?'
168 restorecon -R -v /srv/mysaslauthd_content
169 Note: SELinux often uses regular expressions to specify labels that
171 match multiple files.
172 The following file types are defined for saslauthd:
174 saslauthd_exec_t
178 - Set files with the saslauthd_exec_t type, if you want to transition
180 an executable to the saslauthd_t domain.
181 saslauthd_initrc_exec_t
185 - Set files with the saslauthd_initrc_exec_t type, if you want to tran‐
187 sition an executable to the saslauthd_initrc_t domain.
188 saslauthd_keytab_t
192 - Set files with the saslauthd_keytab_t type, if you want to treat the
194 files as kerberos keytab files.
195 saslauthd_var_run_t
199 - Set files with the saslauthd_var_run_t type, if you want to store the
201 saslauthd files under the /run or /var/run directory.
202 Paths:
205 /var/lib/sasl2(/.*)?, /var/run/saslauthd(/.*)?
206 Note: File context can be temporarily modified with the chcon command.
209 If you want to permanently change the file context you need to use the
210 semanage fcontext command. This will modify the SELinux labeling data‐
211 base. You will need to use restorecon to apply the labels.
212
215 semanage fcontext can also be used to manipulate default file context
216 mappings.
217 semanage permissive can also be used to manipulate whether or not a
219 process type is permissive.
220 semanage module can also be used to enable/disable/install/remove pol‐
222 icy modules.
223 semanage boolean can also be used to manipulate the booleans
225 system-config-selinux is a GUI tool available to customize SELinux pol‐
228 icy settings.
