Tomcat 7 Manager can't login

Question

Trying to log in but can\'t. My tomcat-users.xml, modified as I saw it here.

Answer 1

Ubuntu Server 14.04.3 tomcat7 installed from repo

What worked for me was removing the role definitions from the tomcat-users.xml file. and then restarting tomcat.

my file now looks like this:

Notice the instructions tell you to define the user who belongs to manager-gui but it does not tell you to define the role "manager-gui"
