 - customized SimpleLDAPAuthentication using LDAPS simple bind for authentication
-- customized SimpleACLAuthorizer using LDAPS compare-matched for group membership verification
+- In release 1.1.0 we have had support for authorization which is compatible to Kafka 2.8.1
+- The authorization feature was removed due to incompatibilites with latest Kafka versions (3.0 onwards) starting with release 2.0.0.
 
 Thus, moving authentication from user and passwords in JAAS context file on kafka brokers to LDAP server
 
-By defining Read/Write allowance with LDAP groups, authorization is moved from
-Zookeeper Access Control Lists to group membership verification.
-
 Binding and group membership information is cached (limited lifetime after write),
 giving minor performance penalty and reduced LDAPS traffic.
