Active Directory syncer

The Active Directory syncer pulls users from Microsoft Active Directory into Casdoor over LDAP or LDAPS and keeps the directory in sync.

Prerequisites

You need:

• An Active Directory domain controller accessible via network
• A service account with read permissions to the user directory
• The Base DN (search base) for your user directory
• Network connectivity on LDAP port 389 (or LDAPS port 636 for secure connection)

Configuration

To create an Active Directory syncer in Casdoor:

1. Navigate to the Syncers tab
2. Click Add to create a new syncer
3. Fill in the following required fields:

Field	Description	Example
Organization	The Casdoor organization where users will be imported	my-org
Name	A unique identifier for this syncer	ad-syncer
Type	Select "Active Directory"	Active Directory
Server	Hostname or IP address of your AD domain controller	dc.example.com
LDAP Port	LDAP port (389 for LDAP, 636 for LDAPS)	389
Bind DN	Distinguished name of the service account	CN=Service Account,CN=Users,DC=example,DC=com
Password	Password for the service account	your-password
Base DN	Search base for users	DC=example,DC=com

Leave database-related fields (Database type, Database, Table) empty for the Active Directory syncer.

For production environments, it's recommended to use LDAPS (port 636) for secure communication with Active Directory.

Field Mappings

The syncer automatically maps Active Directory user attributes to Casdoor user fields:

Active Directory Field	Casdoor Field	Description
objectGUID	Id	User's unique identifier (GUID)
sAMAccountName	Name	Username (login name)
displayName	DisplayName	Display name
givenName	FirstName	First name
sn	LastName	Last name
mail	Email	Email address
mobile	Phone	Mobile phone number
title	Title	Job title
department	Affiliation	Department
userAccountControl	IsForbidden	Account status

bilgi

userAccountControl bit 2 indicates a disabled account; those users are marked as forbidden in Casdoor.

Running the syncer

1. Click Test Connection to verify connectivity and credentials.
2. Toggle Is enabled and click Sync for an immediate run.
3. The syncer fetches all user accounts under the Base DN using the filter (&(objectClass=user)(objectCategory=person)) (computers and other AD objects are excluded).

Troubleshooting

If the syncer fails to connect or retrieve users, check the following:

• Verify network connectivity to the AD domain controller on the LDAP port
• Ensure the Bind DN and password are correct
• Confirm the service account has read permissions on the Base DN
• Check that the Base DN is correctly formatted (e.g., DC=example,DC=com)
• Verify firewall rules allow LDAP traffic from Casdoor to the domain controller
