Directory Sync Tool

Synchronise multiple directories & build a global directory easily with UnitySync.

Active Directory is not the only directory...

The reality is that most enterprises have several incompatible or separate directories that underpin myriad corporate messaging, application access and security systems.

There are many technical and business reasons why you'd want to keep these directories in sync with each other.  Equally there are many reasons - often political - why you'd want these directories to remain separate. 

UnitySync is an easy directory synchronisation tool that provides a centrally managed service via which you can keep content in different directories, resource databases - even spreadsheets - in step with each other.

Virtually all LDAP directories, cloud directories and databases can be synchronised.

UnitySync does not itself become the main directory and it doesn't create a central, master directory.  It simply synchronises directory information, so there's no issues over politics or maintaining yet another directory!

It’s also incredibly easy to configure and can save months of effort in say, building a global directory, using Microsoft's Azure Active Directory Connect tool (formerly DirSync) and other 3rd party tools.

You can also use UnitySync in combination with other tools like Active Directory Migration Tool (ADMT) and Azure AD Sync Services.

Independent MVP Review

"I have seen UnitySync in use at a range of customers, from government to manufacturing companies.  It’s a fairly compact, easy to install and easy to configure package...The difference between UnitySync and the alternatives I’ve seen and used is that it makes the task of building a global directory very simple and straightforward...UnitySync didn’t disappoint."

- Steve Goodman, Product Review: UnitySync

Why would you need a directory synchronisation tool?

Secure, Inter-company Updates

For large organisations that have disparate messaging systems, or
communicate regularly with ‘partner’ organisations, keeping inter-domain directory services up-to-date can be challenging.

For example companies often won’t agree to a single schema or allow write access to their directories. UnitySync eliminates these issues: each party keeps their own directory, and UnitySync automatically synchronises the relevant data. Where encrypted messaging is used, UnitySync can also synchronise Public Keys.

Provisioning User Accounts

Each time an employee is added to your HR or ERP database (e.g. PeopleSoft, Sage Group, Kronos, SAP, Oracle, ABRA, ADP), UnitySync can automatically propagate their details into Active Directory (AD) in order to provision an account on-premises or in Office 365.  You can also update other business systems such as a PABX system or company phone book (white pages).

Similarly user accounts can be amended, disabled or deleted when employee records are updated.

This is vital, as failing to de-provision a user account in AD in a timely fashion when a member of staff leaves can create a huge security risk.


Hybrid Exchange Services, Contingency & Co-Existence

UnitySync eases Exchange migrations and long-term co-existence of say, onsite and hosted (Office 365) services, by synchronising AD domains, or multiple AD Forests (and enabling cross forest migrations).

You can also use UnitySync to create ‘Mail Enabled User Objects’ in a separate AD Forest that can be activated as an emergency server.

Maintaining a Common Domain Name

Sometimes it’s useful to standardise on a corporate email address but still have multiple ‘internal’ domains, e.g. following a takeover, merger or acquisition.

UnitySync’s Swap Proxy function can be used to update Exchange primary email addresses for the 'outside world', switching the old address into the secondary or‘proxy’ address list. Other approaches to handling email address unification are also available.

We have recently merged with another company and we are both running our own domain/Exchange environments and are under increasing pressure to have all users appear in both companies (sic) address books. We were initially looking at using the MS tools (IIFP) to do this, but after seeing what UnitySync can do, the solution looks a lot easier and would allow us to both keep control of our own environments (something I’m sure both IT departments are keen to do, I know we are!)

We have been using UnitySync for a number of years and have been extremely happy with the product and quality of service we have been provided with. It is extremely easy to configure and to set up any new connections with a variety of different directory types. Any issues or questions are promptly addressed and answered to our satisfaction. Due to this we have actually recommended the usage of UnitySync to our colleagues and clients as they have identified new requirements. This has resulted in an increased usage of the product within our department.
