Yes, MikroTik RouterOS is capable of integrating with external directory systems, including Microsoft Active Directory (AD) and Lightweight Directory Access Protocol (LDAP). This integration allows MikroTik devices to use centralized user databases for authentication, authorization and accounting, making it easier to manage users and enforce security policies on large networks.

To configure Active Directory integration, you generally need to adjust the RADIUS settings on the MikroTik RouterOS, since AD ​​can act as a RADIUS server with the proper configuration and complementary services. This allows user authentication based on credentials stored in the Active Directory.

For LDAP, the configuration may vary depending on the specific needs and structure of your network. MikroTik RouterOS can be configured to query an LDAP server for user authentication. This is especially useful in environments where LDAP is already used for identity and access management.

Implementing these integrations may require advanced knowledge of MikroTik RouterOS, as well as a solid understanding of Active Directory or LDAP. It is advisable to review the official MikroTik documentation and possibly consult with an experienced MikroTik and directory systems professional to ensure a successful implementation.
