6 nslcd_selinux - Security Enhanced Linux Policy for the nslcd processes
7
9 Security-Enhanced Linux secures the nslcd processes via flexible manda‐
10 tory access control.
11 The nslcd processes execute with the nslcd_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep nslcd_t
19
23 The nslcd_t SELinux type can be entered via the nslcd_exec_t file type.
24 The default entrypoint paths for the nslcd_t domain are the following:
26 /usr/sbin/nslcd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 nslcd policy is very flexible allowing users to setup their nslcd pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for nslcd:
40 nslcd_t
42 Note: semanage permissive -a nslcd_t can be used to make the process
44 type nslcd_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. nslcd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run nslcd with the tightest access possible.
53 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59 setsebool -P authlogin_nsswitch_use_ldap 1
61 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66 setsebool -P fips_mode 1
68 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73 setsebool -P kerberos_enabled 1
75 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80 setsebool -P nis_enabled 1
82 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Enabled by default.
87 setsebool -P nscd_use_shm 1

93 The SELinux process type nslcd_t can manage files labeled with the fol‐
94 lowing file types. The paths listed are the default paths for these
95 file types. Note the processes UID still need to have DAC permissions.

138 SELinux requires files to have an extended attribute to define the file
139 type.
140 You can see the context of a file using the -Z option to ls
142 Policy governs the access confined processes have to these files.
144 SELinux nslcd policy is very flexible allowing users to setup their
145 nslcd processes in as secure a method as possible.
146 STANDARD FILE CONTEXT
148 SELinux defines the file context types for the nslcd, if you wanted to
150 store files with these types in a diffent paths, you need to execute
151 the semanage command to sepecify alternate labeling and then use
152 restorecon to put the labels on disk.
153 semanage fcontext -a -t nslcd_conf_t '/srv/mynslcd_content(/.*)?'
155 restorecon -R -v /srv/mynslcd_content
156 Note: SELinux often uses regular expressions to specify labels that
158 match multiple files.
159 The following file types are defined for nslcd:
161 nslcd_conf_t
165 - Set files with the nslcd_conf_t type, if you want to treat the files
167 as nslcd configuration data, usually stored under the /etc directory.
168 nslcd_exec_t
172 - Set files with the nslcd_exec_t type, if you want to transition an
174 executable to the nslcd_t domain.
175 nslcd_initrc_exec_t
179 - Set files with the nslcd_initrc_exec_t type, if you want to transi‐
181 tion an executable to the nslcd_initrc_t domain.
182 nslcd_var_run_t
186 - Set files with the nslcd_var_run_t type, if you want to store the
188 nslcd files under the /run or /var/run directory.
189 Note: File context can be temporarily modified with the chcon command.
193 If you want to permanently change the file context you need to use the
194 semanage fcontext command. This will modify the SELinux labeling data‐
195 base. You will need to use restorecon to apply the labels.
196
199 semanage fcontext can also be used to manipulate default file context
200 mappings.
201 semanage permissive can also be used to manipulate whether or not a
203 process type is permissive.
204 semanage module can also be used to enable/disable/install/remove pol‐
206 icy modules.
207 semanage boolean can also be used to manipulate the booleans
209 system-config-selinux is a GUI tool available to customize SELinux pol‐
212 icy settings.
