NAME

6       groupadd_selinux - Security Enhanced Linux Policy for the groupadd pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  groupadd  processes  via  flexible
11       mandatory access control.
12
13       The  groupadd  processes  execute with the groupadd_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 groupadd_t
20
21
22

ENTRYPOINTS

24       The groupadd_t SELinux type can be entered via the groupadd_exec_t file
25       type.
26
27       The default entrypoint paths for the groupadd_t domain are the  follow‐
28       ing:
29
30       /usr/bin/gpasswd,         /usr/sbin/gpasswd,        /usr/sbin/groupadd,
31       /usr/sbin/groupdel, /usr/sbin/groupmod
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       groupadd policy is very flexible allowing users to setup their groupadd
41       processes in as secure a method as possible.
42
43       The following process types are defined for groupadd:
44
45       groupadd_t
46
47       Note: semanage permissive -a groupadd_t can be used to make the process
48       type groupadd_t permissive. SELinux does not deny access to  permissive
49       process  types, but the AVC (SELinux denials) messages are still gener‐
50       ated.
51
52

BOOLEANS

54       SELinux  policy  is  customizable  based  on  least  access   required.
55       groupadd  policy  is  extremely  flexible and has several booleans that
56       allow you to manipulate the policy and run groupadd with  the  tightest
57       access possible.
58
59
60
61       If you want to allow users to resolve user passwd entries directly from
62       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
63       gin_nsswitch_use_ldap boolean. Disabled by default.
64
65       setsebool -P authlogin_nsswitch_use_ldap 1
66
67
68
69       If you want to allow all domains to execute in fips_mode, you must turn
70       on the fips_mode boolean. Enabled by default.
71
72       setsebool -P fips_mode 1
73
74
75
76       If you want to allow confined applications to run  with  kerberos,  you
77       must turn on the kerberos_enabled boolean. Enabled by default.
78
79       setsebool -P kerberos_enabled 1
80
81
82
83       If  you  want  to  allow  system  to run with NIS, you must turn on the
84       nis_enabled boolean. Disabled by default.
85
86       setsebool -P nis_enabled 1
87
88
89
90       If you want to allow confined applications to use nscd  shared  memory,
91       you must turn on the nscd_use_shm boolean. Disabled by default.
92
93       setsebool -P nscd_use_shm 1
94
95
96
97       If  you want to allow samba to act as the domain controller, add users,
98       groups and change passwords, you must  turn  on  the  samba_domain_con‐
99       troller boolean. Disabled by default.
100
101       setsebool -P samba_domain_controller 1

MANAGED FILES

106       The  SELinux  process type groupadd_t can manage files labeled with the
107       following file types.  The paths listed are the default paths for these
108       file types.  Note the processes UID still need to have DAC permissions.
109
110       faillog_t
111
112            /var/log/btmp.*
113            /var/log/faillog.*
114            /var/log/tallylog.*
115            /var/run/faillock(/.*)?
116
117       lastlog_t
118

FILE CONTEXTS

156       SELinux requires files to have an extended attribute to define the file
157       type.
158
159       You can see the context of a file using the -Z option to ls
160
161       Policy governs the access  confined  processes  have  to  these  files.
162       SELinux  groupadd policy is very flexible allowing users to setup their
163       groupadd processes in as secure a method as possible.
164
165       The following file types are defined for groupadd:
166
167
168
169       groupadd_exec_t
170
171       - Set files with the groupadd_exec_t type, if you want to transition an
172       executable to the groupadd_t domain.
173
174
175       Paths:
176            /usr/bin/gpasswd,      /usr/sbin/gpasswd,      /usr/sbin/groupadd,
177            /usr/sbin/groupdel, /usr/sbin/groupmod
178
179
180       Note: File context can be temporarily modified with the chcon  command.
181       If  you want to permanently change the file context you need to use the
182       semanage fcontext command.  This will modify the SELinux labeling data‐
183       base.  You will need to use restorecon to apply the labels.
184
185

COMMANDS

187       semanage  fcontext  can also be used to manipulate default file context
188       mappings.
189
190       semanage permissive can also be used to manipulate  whether  or  not  a
191       process type is permissive.
192
193       semanage  module can also be used to enable/disable/install/remove pol‐
194       icy modules.
195
196       semanage boolean can also be used to manipulate the booleans
197
198
199       system-config-selinux is a GUI tool available to customize SELinux pol‐
200       icy settings.
