LDAPAuthenticator.java 168 NullPointerException #5

Closed ghost closed 5 years ago

ghost commented 5 years ago

Hi,

I have followed the steps under "Configuration". When starting cassandra, I am getting the below NPE (apache-cassandra-3.11.3 $ bin/cassandra -f).

Any idea? Not sure when/where private static ClientState state; is initialized.

Best regards, Bernhard

+1 on this. Would like to understand as well how ClientState state gets instantiated.

Hi @bkk2918 and @migscabral

please use the current branch 3.11. We will get rid of master soon as there is a bug which prevents you from running this successfully.

I have tested the current branch 3.11 which goes against Cassandra 3.11.4 with OpenLDAP server (setup is in the README) and I was able to connect without problems. Please let me know if you have any problems.
