What did you do?

I was add 3 line to cassandra.yaml

authenticator: LDAPAuthenticator authorizer: CassandraAuthorizer role_manager: LDAPCassandraRoleManager

I was built mvn with this project, and then copy file cassandra-ldap-4.1.0-1.1.0.jar to /usr/share/cassandra/lib/ -> /usr/share/cassandra/lib/cassandra-ldap-4.1.0-1.1.0.jar
I also created ldap.properties in /etc/cassandra/conf ( im use Oracle ) here is detail

# Ldap server URI. Specify ldaps when using a secure LDAP port (strongly recommended)
# ldap_uri: ldaps://127.0.0.1:636/dc=example,dc=org
ldap_uri=ldaps://xxx-xxx-xxx:389

# Service user distinguished name. This user will be a SUPERUSER and be used for looking up
# user details on authentication
service_dn=serviceaccount@domain (1)

# Service user password
service_password=xxxxxxxxxx

# filter used for searching in LDAP, "%s" is placeholder, it will be replaced by login name
filter_template=(cn=%s)

# True by default, tells whether internal cache of user -> password combination will be used
# This option is irrelevant for Cassandra version <= 3.0
#auth_cache_enabled: false

# if you set this property, Cassandra will internally consider 'dba` to be same as 'cassandra'.
# so you might get rid of `cassandra` role (not recommended) or you might make it unable to log in at least.
# You need to create this admin role beforehand, it has to be super user.
cassandra_ldap_admin_user=serviceaccount@domain ( same as (1))
# consistency level to use for retrieval of a role to check if it can log in - defaults to LOCAL_ONE
#consistency_for_role: LOCAL_ONE

# Default role for new users to be added to
default_role_membership=default_role

What did you expect to see?

After config everything, and i ran systemctl restart casssandra.services for apply new config. I detected the port 9042 doesn't open anymore. I use cmd to check netstat -tln and don't see port 9042 open. So that i cannot use command cqlsh -u user1 -p xxx --ssl for login or cannot do some thing else.

What did you see instead?

Error: Connection error: ('Unable to connect to any servers', {'12.345.678.910:9042': ConnectionRefusedError(111, "Tried connecting to [('12.345.678.910', 9042)]. Last error: Connection refused")})
