Tomcat não autentica usuário

Front-end
#1

Pessoal,

Eu consigo levantar o servidor dentro do Eclipse, mas o Tomcat 7.0.25 não está autenticando o usuário.
Segue, abaixo, o arquivo tomcat-users.xml

<?xml version='1.0' encoding='utf-8'?>

</tomcat-users>

Eu consigo dar “start” no server dentro do Eclipse Indigo.
Quando tento usar o comando

http://localhost:8080/admin

e preencho os campos com o username e a password do arquivo tomcat-users.xml, ele não só não autentica, como fica na mesma caixa de diálogo, solicitando usuário e senha, não consegue autenticar e não saí disto.

Agradeço a quem puder me ajudar.

Erro de escrita na linha 30.
Basta mudar para:

  <role rolename="manager"/>
