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
12 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
16 For example:
17
18 ps -eZ | grep nslcd_t
19
20
21
23 The nslcd_t SELinux type can be entered via the nslcd_exec_t file type.
24
25 The default entrypoint paths for the nslcd_t domain are the following:
26
27 /usr/sbin/nslcd
28
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 nslcd policy is very flexible allowing users to setup their nslcd pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for nslcd:
40
41 nslcd_t
42
43 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
48
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
54
55
56 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
63 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65
66 setsebool -P nis_enabled 1
67
68
69
71 The SELinux process type nslcd_t can manage files labeled with the fol‐
72 lowing file types. The paths listed are the default paths for these
73 file types. Note the processes UID still need to have DAC permissions.

131 SELinux requires files to have an extended attribute to define the file
132 type.
133
134 You can see the context of a file using the -Z option to ls
135
136 Policy governs the access confined processes have to these files.
137 SELinux nslcd policy is very flexible allowing users to setup their
138 nslcd processes in as secure a method as possible.
139
140 STANDARD FILE CONTEXT
141
142 SELinux defines the file context types for the nslcd, if you wanted to
143 store files with these types in a diffent paths, you need to execute
144 the semanage command to specify alternate labeling and then use re‐
145 storecon to put the labels on disk.
146
147 semanage fcontext -a -t nslcd_conf_t '/srv/mynslcd_content(/.*)?'
148 restorecon -R -v /srv/mynslcd_content
149
150 Note: SELinux often uses regular expressions to specify labels that
151 match multiple files.
152
153 The following file types are defined for nslcd:
154
155
156
157 nslcd_conf_t
158
159 - Set files with the nslcd_conf_t type, if you want to treat the files
160 as nslcd configuration data, usually stored under the /etc directory.
161
162
163
164 nslcd_exec_t
165
166 - Set files with the nslcd_exec_t type, if you want to transition an
167 executable to the nslcd_t domain.
168
169
170
171 nslcd_initrc_exec_t
172
173 - Set files with the nslcd_initrc_exec_t type, if you want to transi‐
174 tion an executable to the nslcd_initrc_t domain.
175
176
177
178 nslcd_var_run_t
179
180 - Set files with the nslcd_var_run_t type, if you want to store the
181 nslcd files under the /run or /var/run directory.
182
183
184
185 Note: File context can be temporarily modified with the chcon command.
186 If you want to permanently change the file context you need to use the
187 semanage fcontext command. This will modify the SELinux labeling data‐
188 base. You will need to use restorecon to apply the labels.
189
190
192 semanage fcontext can also be used to manipulate default file context
193 mappings.
194
195 semanage permissive can also be used to manipulate whether or not a
196 process type is permissive.
197
198 semanage module can also be used to enable/disable/install/remove pol‐
199 icy modules.
200
201 semanage boolean can also be used to manipulate the booleans
202
203
204 system-config-selinux is a GUI tool available to customize SELinux pol‐
205 icy settings.
