<code>
### loading the module is mostly not required - it's already loaded
# ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/openldap/schema/ppolicy.ldif

### lets create a new OU for policies
$ cat >polou.ldif<<EOF
dn: ou=policies,dc=fluxcoil,dc=net
objectClass: top
objectClass: organizationalUnit
ou: policies
description: My Organization policies come here
EOF
$ ldapadd -D cn=manager,dc=fluxcoil,dc=net -w secret -f polou.ldif

### add ppolicy
$ cat >ppmodule.ldif<<EOF 
dn: cn=module,cn=config
objectClass: olcModuleList
cn: module
olcModuleLoad: ppolicy
EOF
$ ldapadd -Y EXTERNAL -H ldapi:/// -f ppmodule.ldif

### add the pwdoverlay, our database here is bdb
$ cat >pwdpolicyoverlay.ldif<<EOT
dn: olcOverlay={0}ppolicy,olcDatabase={2}bdb,cn=config
objectClass: olcOverlayConfig
objectClass: olcPPolicyConfig
olcOverlay: {0}ppolicy
olcPPolicyDefault: cn=default,ou=policies,dc=fluxcoil,dc=net
EOT
$ ldapadd -Y EXTERNAL -H ldapi:/// -f pwdpolicyoverlay.ldif
