NAME

6       saslauthd_selinux  -  Security  Enhanced Linux Policy for the saslauthd
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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.

MANAGED FILES

178       The  SELinux process type saslauthd_t can manage files labeled with the
179       following file types.  The paths listed are the default paths for these
180       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

252       SELinux requires files to have an extended attribute to define the file
253       type.
254
255       You can see the context of a file using the -Z option to ls
256
257       Policy governs the access  confined  processes  have  to  these  files.
258       SELinux saslauthd policy is very flexible allowing users to setup their
259       saslauthd processes in as secure a method as possible.
260
261       STANDARD FILE CONTEXT
262
263       SELinux defines the file context types for the saslauthd, if you wanted
264       to store files with these types in a diffent paths, you need to execute
265       the semanage command  to  sepecify  alternate  labeling  and  then  use
266       restorecon to put the labels on disk.
267
268       semanage  fcontext  -a  -t  saslauthd_var_run_t  '/srv/mysaslauthd_con‐
269       tent(/.*)?'
270       restorecon -R -v /srv/mysaslauthd_content
271
272       Note: SELinux often uses regular expressions  to  specify  labels  that
273       match multiple files.
274
275       The following file types are defined for saslauthd:
276
277
278
279       saslauthd_exec_t
280
281       -  Set  files with the saslauthd_exec_t type, if you want to transition
282       an executable to the saslauthd_t domain.
283
284
285
286       saslauthd_initrc_exec_t
287
288       - Set files with the saslauthd_initrc_exec_t type, if you want to tran‐
289       sition an executable to the saslauthd_initrc_t domain.
290
291
292
293       saslauthd_keytab_t
294
295       -  Set files with the saslauthd_keytab_t type, if you want to treat the
296       files as kerberos keytab files.
297
298
299
300       saslauthd_var_run_t
301
302       - Set files with the saslauthd_var_run_t type, if you want to store the
303       saslauthd files under the /run or /var/run directory.
304
305
306       Paths:
307            /var/lib/sasl2(/.*)?, /var/run/saslauthd(/.*)?
308
309
310       Note:  File context can be temporarily modified with the chcon command.
311       If you want to permanently change the file context you need to use  the
312       semanage fcontext command.  This will modify the SELinux labeling data‐
313       base.  You will need to use restorecon to apply the labels.
314
315

COMMANDS

317       semanage fcontext can also be used to manipulate default  file  context
318       mappings.
319
320       semanage  permissive  can  also  be used to manipulate whether or not a
321       process type is permissive.
322
323       semanage module can also be used to enable/disable/install/remove  pol‐
324       icy modules.
325
326       semanage boolean can also be used to manipulate the booleans
327
328
329       system-config-selinux is a GUI tool available to customize SELinux pol‐
330       icy settings.
