6 sysadm_passwd_selinux - Security Enhanced Linux Policy for the
7 sysadm_passwd processes
8
10 Security-Enhanced Linux secures the sysadm_passwd processes via flexi‐
11 ble mandatory access control.
12
13 The sysadm_passwd processes execute with the sysadm_passwd_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep sysadm_passwd_t
20
21
22
24 The sysadm_passwd_t SELinux type can be entered via the
25 admin_passwd_exec_t file type.
26
27 The default entrypoint paths for the sysadm_passwd_t domain are the
28 following:
29
30 /usr/bin/vigr, /usr/bin/vipw, /usr/sbin/vigr, /usr/sbin/vipw,
31 /usr/sbin/pwconv, /usr/sbin/grpconv, /usr/sbin/pwunconv,
32 /usr/sbin/grpunconv
33
35 SELinux defines process types (domains) for each process running on the
36 system
37
38 You can see the context of a process using the -Z option to ps
39
40 Policy governs the access confined processes have to files. SELinux
41 sysadm_passwd policy is very flexible allowing users to setup their
42 sysadm_passwd processes in as secure a method as possible.
43
44 The following process types are defined for sysadm_passwd:
45
46 sysadm_passwd_t
47
48 Note: semanage permissive -a sysadm_passwd_t can be used to make the
49 process type sysadm_passwd_t permissive. SELinux does not deny access
50 to permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
53
55 SELinux policy is customizable based on least access required.
56 sysadm_passwd policy is extremely flexible and has several booleans
57 that allow you to manipulate the policy and run sysadm_passwd with the
58 tightest access possible.

61
62 If you want to allow users to resolve user passwd entries directly from
63 ldap rather then using a sssd server, you must turn on the authlo‐
64 gin_nsswitch_use_ldap boolean. Disabled by default.
65
66 setsebool -P authlogin_nsswitch_use_ldap 1
67
68
69
70 If you want to allow all domains to execute in fips_mode, you must turn
71 on the fips_mode boolean. Enabled by default.
72
73 setsebool -P fips_mode 1
74
75
76
77 If you want to allow confined applications to run with kerberos, you
78 must turn on the kerberos_enabled boolean. Enabled by default.
79
80 setsebool -P kerberos_enabled 1
81
82
83
84 If you want to allow system to run with NIS, you must turn on the
85 nis_enabled boolean. Disabled by default.
86
87 setsebool -P nis_enabled 1
88
89
90
91 If you want to allow confined applications to use nscd shared memory,
92 you must turn on the nscd_use_shm boolean. Disabled by default.
93
94 setsebool -P nscd_use_shm 1
95
96
97
99 The SELinux process type sysadm_passwd_t can manage files labeled with
100 the following file types. The paths listed are the default paths for
101 these file types. Note the processes UID still need to have DAC per‐
102 missions.

107 /etc/passwd[-+]?

133 semanage fcontext can also be used to manipulate default file context
134 mappings.
135
136 semanage permissive can also be used to manipulate whether or not a
137 process type is permissive.
138
139 semanage module can also be used to enable/disable/install/remove pol‐
140 icy modules.
141
142 semanage boolean can also be used to manipulate the booleans
143
144
145 system-config-selinux is a GUI tool available to customize SELinux pol‐
146 icy settings.
