This "how-to-connect" documentation will explain the initial configuration of an example connection from Active Directory to a SharePoint Online List in Office 365. We will be synchronizing data stored in Active Directory.
This guide presupposes that you have installed the Layer2 Cloud Connector and that you are familiar with its basic functionality. The Layer2 Cloud Connector User Documentation will provide you with all necessary information.
2. Configuring the Layer2 Cloud Connector
2.2 Configuring the Data Entity 1
2.3 Configuring the Data Entity 2
To connect to Active Directory, you are going to need the server name and the domain controller name. You can find this information in your Server Manager/Local Server.
We also need the Base DN. The Base DN is based on the directory you want to set to be the root directory for searches and the DC. In our case, Users will be the root directory.
The last we need is an user account with the rights to access the Active Directory. If you are reading and writing, make sure your user has the rights to.
Create a new connection by using the Create New Connection option in the Actions pane (right-hand side). The new connection will appear at the bottom of the Connection Manager List (left-hand side). Click on your newly created connection to open the connection configuration settings.
Choose a meaningful name for your connection and replace the current "New Connection" Connection Title with it.
Connections to Active Directory can be bi-directional. An initial connection should always be uni-directional to assure that both data entities are identical before switching to bi-directional. Therefore, choose Left to Right as Direction. You can change this setting after your initial synchronisation finished successfully.
We will now set up our Data Entities. Go to the data entity “Data Entity 1” to open the configuration settings.
Choose a Data Entity Title. It is recommended to give your entities meaningful names to maintain an overview when you decide to set up multiple connections.
Select the Data Provider for Active Directory from the data provider list. You can search for Active Directory by typing into the selection box.
For the Connection String, we need the information mentioned in step 1. You can copy the below connection string and adjust it to match your gathered information. Use the Verify Connection String option to evaluate if the provided connection string is valid.
Server=srv;Port=389;User="l2-dev-sp2016\Administrator";BaseDN="CN=Users,DC=l2-dev-sp2016,DC=local";Other="DefaultColumnSize=8000";
Enter the user account's password into the Password field. The field masks the value for better security.
The Select Statement text box is used to define specific data queries. We will be gathering all information from the User table. You can copy the below select statement and adjust it to match your needs. Save your changes by using the right-hand pane option Save Changes.
SELECT * FROM User
To check if all necessary columns are received, you can use the Preview Data option on the right-hand pane which will provide you with a pop-up window showing your sample data from your Active Directory entity.
We are going to send the data to a custom SharePoint Online list. It's required that you set up this list prior to the next steps. Your list should contain matching columns according to your source entity.
Use the left-hand pane to switch to the data entity "Data Entity 2". We will be using the Layer2 SharePoint Provider for this setup.
For more information about the SharePoint provider visit:
https://www.layer2solutions.com/support/cloud-connector-faqs/layer2-csom-sharepoint-ado-net-provider.
You can copy the below Connection String which contains the minimum of required properties to connect to your custom SharePoint Online list.
URL=https://your_custom_sharepoint_list_url/AllItems.aspx;Authentication=Office365;[email protected];
Enter the password that belongs to the user account used in the connection string into the Password field. Save your changes by using the right-hand pane option Save Changes.
In the next step, we will configure our mapping settings. Click on the Mappings option on the left-hand pane. If your fields from SharePoint are named identical to the fields from your source system, the Enable Auto Mapping option will match those columns. Disabling this option allows you to match your columns as needed. Save your changes by using the right-hand pane option Save Changes.
To run your connection switch back to the main connection configuration node and use the Run Now Button located on the bottom of the setup page. The Run Synchronization Toolbox will also display the synchronization process.
Below is a data preview of the information we have accessed in our source entity:
This will be the result in our SharePoint Online list after our initial successful synchronization:
If you want to use a bi-directional synchronization, you can now switch your connection direction after our first initial synchronization run finished successfully. See section 3.1 for further information.
As far as tested, this connection supports uni-directional as well as bi-directional synchronizations.
After adjusting the direction to bi-directional, you should check your Mappings settings again because some systems might include read-only columns that cannot be mapped directly: CanonicalName and MemberOf should not be set in bi-directional connections. These fields are set automatically through or can only be set in the Active Directory.
We also recommend choosing a Conflict Resolution that matches your environment's needs. You can find out more about the different conflict resolutions in our Layer2 Cloud Connector User Documentation.
To see all the tables and views you can access with the Active Directory provider, use these queries in the Select Statement:
SELECT * FROM sys_tables
SELECT * FROM sys_views
If there are more tables or views available, you can load them with the option "load more" in the popup window.
Some columns from Active Directory are very large. If you get some error about the size of a returned value, try to increase the size of the columns through the property Other="DefaultColumnSize=8000". The default value for the column is 2000.
