#### Nested groups usage in LDAP/AD
If you are using Active directory with nested groups you have to add LDAP_MATCHING_RULE_IN_CHAIN: :1.2.840.113556.1.4.1941: to your query.
For example:
```shell
group_search_filter: (&(objectClass=group)(member:1.2.840.113556.1.4.1941:=%d))

streaming_max_pub_acks_in_flight  (number)    number of messages to publish without waiting for ACKs
streaming_cluster_id              (string)    unique ID for NATS streaming cluster
cert_authority                    (string)    path to certificate chain of the target NATS server
client_cert                       (string)    client cert for NATS mTLS auth
client_key                        (string)    client cert key for NATS mTLS auth

```

> NOTE: if MinIO distributed setup is already configured to run under TLS, FTP will automatically use the relevant
> certs from the server certificate chain, this is mainly to add simplicity of setup. However if you wish to terminate
