Professional, low-risk migration services from Apple Open Directory (macOS Server LDAP) to enterprise-grade open-source LDAP solutions — OpenLDAP, 389 Directory Server, or FreeIPA/Red Hat Identity Management. Preserve users, groups, macOS client bindings, and Kerberos authentication with minimal disruption.
Start Your Migration ConsultationOur Open Directory to LDAP Migration Services
Apple discontinued macOS Server's Open Directory features years ago, leaving many organizations with aging, unsupported directory services. Zwiegnet helps you migrate safely to modern, actively maintained Linux-based LDAP platforms — leveraging our deep expertise in OpenLDAP and enterprise directories.
We handle the full process: assessment, data export, schema mapping, user/group/principal migration, macOS client rebinding, Kerberos integration, and post-migration support — with zero or near-zero downtime strategies.
Our migration services include:
- Assessment & Planning – Audit your current Open Directory setup (users, groups, policies, macOS bindings, Kerberos principals), identify custom schemas/extensions, and design the target LDAP topology (OpenLDAP multi-master, 389 DS, FreeIPA).
- Data Export & Mapping – Safe LDIF export from Open Directory, schema translation (Apple-specific attributes → standard LDAP), and attribute/objectclass mapping to avoid data loss.
- User, Group & Authentication Migration – Transfer accounts, groups, POSIX attributes, and Kerberos principals; password migration strategies (reset on next login or secure hash transfer where possible).
- macOS Client Rebinding – Reconfigure macOS clients (Directory Utility) to bind to the new LDAP/Kerberos server — automated profiles via MDM or scripts, preserving login, home directories, and policies.
- Kerberos & SSO Integration – Set up cross-realm trusts or new Kerberos realms; ensure single sign-on for macOS, Linux, and mixed environments.
- High Availability & Replication – Build multi-master replication (OpenLDAP MMR / syncrepl, 389 DS), failover, and backup/restore plans.
- Security Hardening & Compliance – TLS/LDAPS, SASL/GSSAPI, ACLs, password policies, and alignment with NIST/CIS standards.
- Testing & Cutover – Staged testing, dry-run migrations, parallel operation, and monitored cutover with rollback options.
- Post-Migration Support – Troubleshooting macOS-specific issues, performance tuning, monitoring integration, and ongoing managed services.
Perfect for schools, creative agencies, research labs, small-to-medium businesses, and enterprises still running legacy macOS Server Open Directory — especially those integrating Macs with Linux servers or moving to modern identity management.
