Are you using Windchill 10.2? There was a change in the way authentication works on 10.2 in an effort to increase security. This change will result in double authentication prompts if you use an alias (any hostname other than the hostname defined in the wt.rmi.server.hostname property) to access Windchill. This includes the 'localhost' alias. But, if you use the exact URL defined in the wt.server.codebase property to access Windchill, then you should only get prompted for authentication once.
