[keycloak-user] Can Keycloak simulate LDAP server?

Hi all, we are interested to know if it is possible to authenticate users of pure LDAP client against Keycloak? Why? We are planning to migrate legacy user storage to Keycloak and we'd like to avoid dead end if for example some product (e.g. SaaS) does not support user authentication against Keycloak, but does against standard LDAP server. If it is impossible, has anybody succeeded to implement reverted direction of user federation synchronization (all users data from Keycloak should be copied to a fresh LDAP server installation)? Answers to these questions may be decisive for the Keycloak usage in our organization. Thank you in advance Valerij Timofeev Software Engineer Trusted Shops GmbH
