NAME

6       slapd_selinux - Security Enhanced Linux Policy for the slapd processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The slapd_t SELinux type can be entered via the slapd_exec_t file type.
24
25       The default entrypoint paths for the slapd_t domain are the following:
26
27       /usr/lib/slapd, /usr/sbin/slapd, /usr/lib/openldap/slapd
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       slapd policy is very flexible allowing users to setup their slapd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for slapd:
40
41       slapd_t
42
43       Note:  semanage  permissive  -a slapd_t can be used to make the process
44       type slapd_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.   slapd
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run slapd with the tightest access possible.

MANAGED FILES

167       The SELinux process type slapd_t can manage files labeled with the fol‐
168       lowing  file  types.   The paths listed are the default paths for these
169       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

264       SELinux requires files to have an extended attribute to define the file
265       type.
266
267       You can see the context of a file using the -Z option to ls
268
269       Policy  governs  the  access  confined  processes  have to these files.
270       SELinux slapd policy is very flexible allowing  users  to  setup  their
271       slapd processes in as secure a method as possible.
272
273       EQUIVALENCE DIRECTORIES
274
275
276       slapd  policy  stores  data  with multiple different file context types
277       under the /var/lib/ldap directory.  If you would like to store the data
278       in  a different directory you can use the semanage command to create an
279       equivalence mapping.  If you wanted to store this data under  the  /srv
280       dirctory you would execute the following command:
281
282       semanage fcontext -a -e /var/lib/ldap /srv/ldap
283       restorecon -R -v /srv/ldap
284
285       STANDARD FILE CONTEXT
286
287       SELinux  defines the file context types for the slapd, if you wanted to
288       store files with these types in a diffent paths, you  need  to  execute
289       the  semanage  command  to  sepecify  alternate  labeling  and then use
290       restorecon to put the labels on disk.
291
292       semanage fcontext -a -t slapd_var_run_t '/srv/myslapd_content(/.*)?'
293       restorecon -R -v /srv/myslapd_content
294
295       Note: SELinux often uses regular expressions  to  specify  labels  that
296       match multiple files.
297
298       The following file types are defined for slapd:
299
300
301
302       slapd_cert_t
303
304       -  Set files with the slapd_cert_t type, if you want to treat the files
305       as slapd certificate data.

345       slapd_keytab_t

350
351
352       slapd_lock_t
353
354       -  Set files with the slapd_lock_t type, if you want to treat the files
355       as slapd lock data, stored under the /var/lock directory
356

358       Paths:
359            /var/lock/subsys/ldap, /var/lock/subsys/slapd
360
361
362       slapd_log_t
363

371
372       slapd_replog_t

409
410
411       Note:  File context can be temporarily modified with the chcon command.
412       If you want to permanently change the file context you need to use  the
413       semanage fcontext command.  This will modify the SELinux labeling data‐
414       base.  You will need to use restorecon to apply the labels.
415
416

COMMANDS

418       semanage fcontext can also be used to manipulate default  file  context
419       mappings.
420
421       semanage  permissive  can  also  be used to manipulate whether or not a
422       process type is permissive.
423
424       semanage module can also be used to enable/disable/install/remove  pol‐
425       icy modules.
426
427       semanage boolean can also be used to manipulate the booleans
428
429
430       system-config-selinux is a GUI tool available to customize SELinux pol‐
431       icy settings.
