NAME

6       sssd_selinux - Security Enhanced Linux Policy for the sssd processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the sssd processes via flexible manda‐
10       tory access control.
11
12       The sssd processes execute with the sssd_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep sssd_t
19
20
21

ENTRYPOINTS

23       The sssd_t SELinux type can be entered via the sssd_exec_t file type.
24
25       The default entrypoint paths for the sssd_t domain are the following:
26
27       /usr/sbin/sssd
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       sssd policy is very flexible allowing users to setup  their  sssd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for sssd:
40
41       sssd_t, sssd_selinux_manager_t
42
43       Note:  semanage  permissive  -a  sssd_t can be used to make the process
44       type sssd_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   sssd
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run sssd with the tightest access possible.

MANAGED FILES

178       The  SELinux process type sssd_t can manage files labeled with the fol‐
179       lowing 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

294       SELinux requires files to have an extended attribute to define the file
295       type.
296
297       You can see the context of a file using the -Z option to ls
298
299       Policy governs the access  confined  processes  have  to  these  files.
300       SELinux sssd policy is very flexible allowing users to setup their sssd
301       processes in as secure a method as possible.
302
303       EQUIVALENCE DIRECTORIES
304
305
306       sssd policy stores data with  multiple  different  file  context  types
307       under  the /var/lib/sss directory.  If you would like to store the data
308       in a different directory you can use the semanage command to create  an
309       equivalence  mapping.   If you wanted to store this data under the /srv
310       dirctory you would execute the following command:
311
312       semanage fcontext -a -e /var/lib/sss /srv/sss
313       restorecon -R -v /srv/sss
314
315       STANDARD FILE CONTEXT
316
317       SELinux defines the file context types for the sssd, if you  wanted  to
318       store  files  with  these types in a diffent paths, you need to execute
319       the semanage command  to  sepecify  alternate  labeling  and  then  use
320       restorecon to put the labels on disk.
321
322       semanage fcontext -a -t sssd_var_run_t '/srv/mysssd_content(/.*)?'
323       restorecon -R -v /srv/mysssd_content
324
325       Note:  SELinux  often  uses  regular expressions to specify labels that
326       match multiple files.
327
328       The following file types are defined for sssd:
329
330
331
332       sssd_exec_t
333
334       - Set files with the sssd_exec_t type, if you  want  to  transition  an
335       executable to the sssd_t domain.
336
337
338
339       sssd_initrc_exec_t
340
341       - Set files with the sssd_initrc_exec_t type, if you want to transition
342       an executable to the sssd_initrc_t domain.
343
344
345
346       sssd_public_t
347
348       - Set files with the sssd_public_t type, if you want to treat the files
349       as sssd public data.
350
351
352       Paths:
353            /var/lib/sss/mc(/.*)?, /var/lib/sss/pubconf(/.*)?
354
355
356       sssd_selinux_manager_exec_t
357
358       -  Set  files with the sssd_selinux_manager_exec_t type, if you want to
359       transition an executable to the sssd_selinux_manager_t domain.
360
361
362
363       sssd_var_lib_t
364
365       - Set files with the sssd_var_lib_t type, if you want to store the sssd
366       files under the /var/lib directory.
367
368
369
370       sssd_var_log_t
371
372       - Set files with the sssd_var_log_t type, if you want to treat the data
373       as sssd var log data, usually stored under the /var/log directory.
374
375
376
377       sssd_var_run_t
378
379       - Set files with the sssd_var_run_t type, if you want to store the sssd
380       files under the /run or /var/run directory.
381
382
383
384       Note:  File context can be temporarily modified with the chcon command.
385       If you want to permanently change the file context you need to use  the
386       semanage fcontext command.  This will modify the SELinux labeling data‐
387       base.  You will need to use restorecon to apply the labels.
388
389

COMMANDS

391       semanage fcontext can also be used to manipulate default  file  context
392       mappings.
393
394       semanage  permissive  can  also  be used to manipulate whether or not a
395       process type is permissive.
396
397       semanage module can also be used to enable/disable/install/remove  pol‐
398       icy modules.
399
400       semanage boolean can also be used to manipulate the booleans
401
402
403       system-config-selinux is a GUI tool available to customize SELinux pol‐
404       icy settings.
