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 all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58 setsebool -P fips_mode 1
60 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65 setsebool -P nis_enabled 1
67
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.

116 SELinux requires files to have an extended attribute to define the file
117 type.
118 You can see the context of a file using the -Z option to ls
120 Policy governs the access confined processes have to these files.
122 SELinux nslcd policy is very flexible allowing users to setup their
123 nslcd processes in as secure a method as possible.
124 STANDARD FILE CONTEXT
126 SELinux defines the file context types for the nslcd, if you wanted to
128 store files with these types in a diffent paths, you need to execute
129 the semanage command to sepecify alternate labeling and then use
130 restorecon to put the labels on disk.
131 semanage fcontext -a -t nslcd_conf_t '/srv/mynslcd_content(/.*)?'
133 restorecon -R -v /srv/mynslcd_content
134 Note: SELinux often uses regular expressions to specify labels that
136 match multiple files.
137 The following file types are defined for nslcd:
139 nslcd_conf_t
143 - Set files with the nslcd_conf_t type, if you want to treat the files
145 as nslcd configuration data, usually stored under the /etc directory.
146 nslcd_exec_t
150 - Set files with the nslcd_exec_t type, if you want to transition an
152 executable to the nslcd_t domain.
153 nslcd_initrc_exec_t
157 - Set files with the nslcd_initrc_exec_t type, if you want to transi‐
159 tion an executable to the nslcd_initrc_t domain.
160 nslcd_var_run_t
164 - Set files with the nslcd_var_run_t type, if you want to store the
166 nslcd files under the /run or /var/run directory.
167 Note: File context can be temporarily modified with the chcon command.
171 If you want to permanently change the file context you need to use the
172 semanage fcontext command. This will modify the SELinux labeling data‐
173 base. You will need to use restorecon to apply the labels.
174
177 semanage fcontext can also be used to manipulate default file context
178 mappings.
179 semanage permissive can also be used to manipulate whether or not a
181 process type is permissive.
182 semanage module can also be used to enable/disable/install/remove pol‐
184 icy modules.
185 semanage boolean can also be used to manipulate the booleans
187 system-config-selinux is a GUI tool available to customize SELinux pol‐
190 icy settings.
