# Synchronizing LDAP Users and Groups

The `sdb-admin sync-ldap` tool (or simply the "LDAP tool") imports users and groups from Lightweight Directory Access Protocol (LDAP) implementations, such as Active Directory into SingleStore. It also helps automatically synchronize the LDAP-implemented directory users and groups with SingleStore and thereby manage users in a central location.

The LDAP tool provides a one-way user and group synchronization from any LDAP directory to SingleStore. The LDAP server does not need to be modified in any way. It also manages LDAP user-group relationships in SingleStore. However, it does not create or manage SingleStore roles and privileges, which are internally managed in SingleStore.

> **📝 Note**: The LDAP tool uses LDAP protocol version 3. It can be used with LDAP implementations with or without Single Sign-On (SSO) support.
