# ldapdock
*_a configurable container running openLDAP_*

Step by step approach on how to setup and run the openLDAP server on a classic systemd-less Docker image container

## _Creating the ldapdock image container_

build ldapdock
```
> docker build -t ldapdock /path/to/dockerfile
```

after build, check the docker image has been created properly with the given REPOSITORY name
```
> docker images
REPOSITORY    TAG       IMAGE ID       CREATED       SIZE
ldapdock      latest    0e4a1521b346   6 hours ago   138MB
```

run into the container to setup openLDAP
```
> docker run -h example.com -i -t ldapdock /bin/bash
```
## _Inside the ldapdock image container_

make sure to use the following command to start openLDAP
```
root@example:/# slapd -h "ldap:/// ldapi:///" -g openldap -u openldap -F /etc/ldap/slapd.d
```

test connectivity to slapd
```
root@example:/# ldapsearch -x -H ldap://localhost -b "dc=example,dc=com" -s base "(objectclass=*)"
# extended LDIF
#
# LDAPv3
# base <dc=example,dc=com> with scope baseObject
...
```

make new test LDAP directories (LDAP OU) and create two attributes/branches with People and Group 
```
root@example:/# vim base.ldif
```

```
dn: ou=People,dc=example,dc=com
objectClass: organizationalUnit
ou: People

dn: ou=Groups,dc=example,dc=com
objectClass: organizationalUnit
ou: Group
```

create the test directory in our LDAP server, the password in the dockerfile by default is _admin_
```
root@example:/# ldapadd -x -D cn=admin,dc=example,dc=com -W -f base.ldif
Enter LDAP Password:
adding new entry "ou=People,dc=example,dc=com"

adding new entry "ou=Groups,dc=example,dc=com"
```

verify the entries in the LDAP server
```
root@example:/# ldapsearch -x -LLL -b dc=example,dc=com 'ou=People' dn
dn: ou=People,dc=example,dc=com
root@example:/# ldapsearch -x -LLL -b dc=example,dc=com 'ou=Groups' dn
dn: ou=Groups,dc=example,dc=com
```
now we have an **Organizational Unit (ou=People, ou=Group, etc.)** with users and groups within an LDAP directory structure correctly created

## _Users administrative tasks_

create a new LDAP directory called Supergirls (LDAP OU) with the following data
```
root@example:/# vim add_ou.ldif
dn: ou=Supergirls,dc=example,dc=com
objectClass: organizationalUnit
ou: Supergirls
```

create it in our LDAP server, when asked for the root password, remember in the dockerfile by default is _admin_
```
root@example:/# ldapadd -x -D "cn=admin,dc=example,dc=com" -W -f add_ou.ldif
Enter LDAP Password:
adding new entry "ou=Supergirls,dc=example,dc=com"
```

verify the entry in the LDAP server
```
root@example:/# ldapsearch -x -LLL -b "dc=example,dc=com" "(ou=Supergirls)" dn
dn: ou=Supergirls,dc=example,dc=com

root@example:/#
```

create a new LDAP password to manage our new directory, and annotate the result hashed password
```
root@example:/# slappasswd
New password:
Re-enter new password:
{SSHA}hashedpasswd
```

create a .ldif file with the necessary attributes to insert in our Supergirls directory
```
root@example:/# vim add_user_supergirls.ldif
dn: uid=marisa,ou=Supergirls,dc=example,dc=com
objectClass: inetOrgPerson
objectClass: posixAccount
cn: Marisa
sn: Kirisame
givenName: Marisa
displayName: Marisa Kirisame
uid: marisa
uidNumber: 1001
gidNumber: 5000
homeDirectory: /home/marisa
loginShell: /bin/bash
userPassword: {SSHA}hashedpasswd
mail: marisa@example.com
```

insert the new user (marisa) in our Supergirls directory (LDAP OU), still using the root password _admin_
```
root@example:/# ldapadd -x -D "cn=admin,dc=example,dc=com" -W -f add_user_supergirls.ldif
Enter LDAP Password:
adding new entry "uid=marisa,ou=Supergirls,dc=example,dc=com"
```

verify the user (marisa) has been added tp tje Supergirls OU
```
root@example:/# ldapsearch -x -LLL -b "dc=example,dc=com" "(uid=marisa)" dn
dn: uid=marisa,ou=Supergirls,dc=example,dc=com
```
