The authc service has started but is unresponsive to authentication requests.
Resolution
Before any steps are taken to resolve the issue, confirm that the installation drive is not at 100% capacity. If the installation drive is full, or nearing capacity, increase disk space accordingly.The authcdb needs to be reconfigured.
Linux:
1. Shutdown NetWorker services: nsr_shutdown2. Rename the authc directory: mv /nsr/authc /nsr/authc`date -I`.bak3. Run the authc configuration script: /opt/nsr/authc-server/scripts/authc_configure.sh
Note: You are prompted to reconfigure the authc keystore and NetWorker Administrator password.
4. Start NetWorker services: systemctl start networker5. Confirm NetWorker services come up: ps -ef | grep nsr6. Confirm port 9090 connections succeed: nsrports -t localhost -p 9090
Note: The authc service appears as a jsvc.exe process for nsrtomcat+. This can be observed with `ps -ef | grep jsvc`
