Hello @(Arasun) Murugarasan Muthukrishnan
Apparently Keycloak is a 3rd Party software for Identity Management that can be integrated with an LDAP infrastructure such as Active Directory. This should not be a problem, but however you should contact the manufacturer of the software or their community forums, to understand what are the specific features, requisites, and configurations to deploy it over Active Directory.
Hope this helps with your query,
