Cause

A configuração padrão monitoring-app.properties para o tamanho do cabeçalho HTTP é 8 KB. O cabeçalho HTTP padrão pode não ser suficiente para acomodar todos os cabeçalhos com configurações grandes de usuário ou grupo do Active Directory.

Resolution

Aumente a configuração do tamanho do cabeçalho HTTP monitoring-app.properties no servidor NetWorker.

  • Pare o "NetWorker Management Web UI Server" serviço:
Linux: 
sudo systemctl stop nwui
Windows: 
net stop nwui
  • Abra o monitoring-app.properties em um editor de texto:
Linux:  
sudo vi /nsr/nwui/monitoring/app/conf/monitoring-app.properties
Windows: 
notepad C:\Program Files\EMC NetWorker\nwui\monitoring\app\conf\monitoring-app.properties
  • Adicionar uma nova linha para o server.max-http-header-size com valor de 32 KB
server.max-http-header-size=32KB
  • Salve as alterações no monitoring-app.properties .
  • Inicie o "NetWorker Management Web UI Server" serviço:
Linux: 
sudo systemctl start nwui
Windows: 
net start nwui
