Tomcat Version 7, unable to log in
===

In my tomcat-users.xml, I have



    <tomcat-users>
    <role rolename="admin-gui"/>
    <role rolename="manager-gui"/>
    <user username="admin" password="pass" roles='admin-gui,manager-gui'/>
    </tomcat-users>

When I try to access `http://localhost:8080/manager/html` using the username and password, it does not log me in. The same authentication box appears again.
