Start

# Create shared network
docker network create ldap-shared-network 2>/dev/null || true

docker compose up -d

# Wait for initialization
sleep 30

Run Tests

./test-password-policy.sh

The script validates:

1. 1 Overlay loaded — ppolicy overlay exists in cn=config
2. 2 Policy OU exists — ou=Policies,dc=test,dc=com is created
3. 3 Default policy exists — cn=default,ou=Policies,dc=test,dc=com with all attributes
4. 4 Policy enforcement — weak passwords rejected, strong passwords accepted

Default Policy

Manual Testing

Check Policy Configuration

ldapsearch -x -H ldap://localhost:391 \
  -D "cn=Manager,dc=test,dc=com" -w admin123 \
  -b "cn=default,ou=Policies,dc=test,dc=com" -s base

Test Weak Password (Should Fail)

ldapadd -x -H ldap://localhost:391 \
  -D "cn=Manager,dc=test,dc=com" -w admin123 <<EOF
dn: uid=weakuser,ou=People,dc=test,dc=com
objectClass: inetOrgPerson
uid: weakuser
cn: Weak User
sn: User
userPassword: 123
EOF

Test Strong Password (Should Succeed)

ldapadd -x -H ldap://localhost:391 \
  -D "cn=Manager,dc=test,dc=com" -w admin123 <<EOF
dn: uid=stronguser,ou=People,dc=test,dc=com
objectClass: inetOrgPerson
uid: stronguser
cn: Strong User
sn: User
userPassword: MySecurePass123!
EOF

Connection Details

Troubleshooting

Policy not enforced — Verify overlay is loaded:

ldapsearch -x -H ldap://localhost:391 \
  -D "cn=Manager,dc=test,dc=com" -w admin123 \
  -b "cn=config" "(objectClass=olcPPolicyConfig)"

Policy entry missing — Check the OU:

ldapsearch -x -H ldap://localhost:391 \
  -D "cn=Manager,dc=test,dc=com" -w admin123 \
  -b "ou=Policies,dc=test,dc=com"

Cleanup

docker compose down -v
