Getting Started With Apacheds

RedHat Enterprise Linux 8 does not include the OpenLDAP server package. To install ApacheDS instead:

    sudo yum install -y java-1.8.0-openjdk
    curl -OL https://dlcdn.apache.org//directory/apacheds/dist/2.0.0.AM26/apacheds-2.0.0.AM26-x86_64.rpm
    sudo rpm -i apacheds-2.0.0.AM26-x86_64.rpm
    sudo vi /opt/apacheds-2.0.0.AM26/conf/wrapper.conf  #Put Java path
    sudo /etc/init.d/apacheds-2.0.0.AM26-default start

Then, install the LDAP client utility to connect to the server:

    sudo yum install -y openldap-clients
    sudo yum install -y vim-enhanced
    ldapsearch -h $(hostname -f):10389 -D 'uid=admin,ou=system' -w 'secret' -b '' -s base

The server contains the example.com partition by default, so we create the user and group with an LDIF:

    echo '
    dn: ou=people,dc=example,dc=com
    objectClass: organizationalUnit
    ou: people

    dn: ou=groups,dc=example,dc=com
    objectClass: organizationalUnit
    ou: groups
    ' > basedn.ldif
    echo '
    dn: uid=user1,ou=people,dc=example,dc=com
    objectClass: inetOrgPerson
    cn: user1
    sn: Person1
    echo "userPassword: $(sudo slappasswd -s 1)" >> ldapUser.ldif
    echo '
    dn: cn=admins,ou=groups,dc=example,dc=com
    objectClass: groupofnames
    cn: admins
    description: Admin users
    member: cn=user1,ou=groups,dc=example,dc=com
    ' >> ldapUser.ldif
    ldapadd -h $(hostname -f):10389 -D 'uid=admin,ou=system' -w 'secret' -f basedn.ldif
    ldapadd -h $(hostname -f):10389 -D 'uid=admin,ou=system' -w 'secret' -f ldapUser.ldif

Fetch the self-signed certificate with:

    openssl s_client -showcerts -connect localhost:10636 </dev/null
