# ldapdock
|
|
*_a configurable container running openLDAP_*
|
|
|
|
Step by step approach on how to setup and run an openLDAP server on a systemd-less docker image container
|
|
|
|
## _1- Creating the ldapdock image container_
|
|
|
|
build ldapdock from the dockerfile and run into it
|
|
|
|
```
|
|
> docker build -t ldapdock /path/to/dockerfile
|
|
```
|
|
|
|
```
|
|
> docker run -h example.com -i -t -v ldap_data:/var/lib/ldap -v ldap_config:/etc/ldap/slapd.d ldapdock /bin/bash
|
|
```
|
|
|
|
## _2- Run the openLDAP server and create an admin user_
|
|
|
|
Use the following command to start openLDAP
|
|
```
|
|
root@example:/# slapd -h "ldap:/// ldapi:///" -g openldap -u openldap -F /etc/ldap/slapd.d
|
|
```
|
|
Generate a password hash for our administrator user, 1234 here being the password
|
|
```
|
|
root@example:/# slappasswd -s 1234
|
|
{SSHA}yxIgYTzcuRRdlesjfWkIN6K97/8jOrZF
|
|
```
|
|
Create the .ldif file that will create the admin user, edit the _userPassword_ attribute with our password hash\
|
|
(you can copy & paste the entire command until userPassword, copy your password hash with the mouse, and paste it directly)
|
|
```
|
|
root@example:/# cat > create_admin.ldif << EOL
|
|
dn: cn=admin,dc=example,dc=com
|
|
changetype: add
|
|
objectClass: organizationalRole
|
|
objectClass: simpleSecurityObject
|
|
cn: admin
|
|
description: LDAP administrator
|
|
userPassword: {SSHA}yxIgYTzcuRRdlesjfWkIN6K97/8jOrZF # Replace with the hash of your password
|
|
EOL
|
|
```
|
|
```
|
|
root@example:/# ldapadd -x -H ldap:/// -D "cn=admin,dc=example,dc=com" -w admin -f create_admin.ldif
|
|
adding new entry "cn=admin,dc=example,dc=com"
|
|
```
|
|
That's all, our administrator user was properly done.
|
|
|
|
## _3- Load and enable policy modules_
|
|
|
|
We need to make use of new schemas and **policies**, which in large part exists in /usr/lib/ppolicy.so -since the module exists, we are going to create modify_ppolicy_module.ldif to be able to make use of it:
|
|
```
|
|
root@example:/# cat > modify_ppolicy_module.ldif << EOL
|
|
dn: cn=module{0},cn=config
|
|
changetype: modify
|
|
add: olcModuleLoad
|
|
olcModuleLoad: ppolicy.so
|
|
EOL
|
|
```
|
|
```
|
|
root@example:/# ldapmodify -Q -Y EXTERNAL -H ldapi:/// -f modify_ppolicy_module.ldif
|
|
modifying entry "cn=module{0},cn=config"
|
|
```
|
|
Reset slapd (openLDAP server)
|
|
```
|
|
root@example:/# kill $(pidof slapd)
|
|
root@example:/# slapd -h "ldap:/// ldapi:///" -g openldap -u openldap -F /etc/ldap/slapd.d
|
|
```
|
|
Now that we restarted our openLDAP server, we can load the new module, so we create the following .ldif file:
|
|
```
|
|
root@example:/# cat > enable_ppolicy.ldif << EOL
|
|
dn: olcOverlay=ppolicy,olcDatabase={1}mdb,cn=config
|
|
changetype: add
|
|
objectClass: olcOverlayConfig
|
|
objectClass: olcPPolicyConfig
|
|
olcOverlay: ppolicy
|
|
olcPPolicyDefault: cn=default,ou=policies,dc=example,dc=com
|
|
EOL
|
|
```
|
|
```
|
|
root@example:/# ldapadd -Q -Y EXTERNAL -H ldapi:/// -f enable_ppolicy.ldif
|
|
adding new entry "olcOverlay=ppolicy,olcDatabase={1}mdb,cn=config"
|
|
```
|
|
The policies module has been loaded and we can begin to configure password schemas and ACLs.
