Unable to view Server Status,Manager App page in Tomcat : Doesn't accept the username and password,why is it so?

Question

I am unable to view the server status and Manager App page in Tomcat.

Though I configured the username and password in tomcat-users.xml,it doesn't accept the combination and shows this message :

401 Unauthorized

You are not authorized to view this page. If you have not changed any configuration  files, please examine the file conf/tomcat-users.xml in your installation. That file must contain the credentials to let you use this webapp.

For example, to add the manager-gui role to a user named tomcat with a password of s3cret, add the following to the config file listed above.

<role rolename="manager-gui"/>
<user username="tomcat" password="s3cret" roles="manager-gui"/>

Note that for Tomcat 7 onwards, the roles required to use the manager application were changed from the single manager role to the following four roles. You will need to assign the role(s) required for the functionality you wish to access.

manager-gui - allows access to the HTML GUI and the status pages
manager-script - allows access to the text interface and the status pages
manager-jmx - allows access to the JMX proxy and the status pages
manager-status - allows access to the status pages only

The HTML interface is protected against CSRF but the text and JMX interfaces are not. To maintain the CSRF protection:

Users with the manager-gui role should not be granted either the manager-script or manager-jmx roles.
If the text or jmx interfaces are accessed through a browser (e.g. for testing since these interfaces are intended for tools not humans) then the browser must be closed afterwards to terminate the session.

I edited tomcat-users.xml as :

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

I put the username and password as suhail. Why doesn't it accept the combination ?

Answer 1

I also struggled a lot. This one worked for me. Copy paste the below to tomcat-users.xml

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

<tomcat-users>
<role rolename="tomcat"/>
<role rolename="role1"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="role1" password="tomcat" roles="role1"/>
 -->
<role rolename="manager-gui" />
<user username="jeril" password="1" roles="manager-gui"/>
</tomcat-users>

Answer 2

add the below line in your tomcat-users.xml to check server status and manager app.

<user username="username" password="password" roles="admin-gui,manager-gui"/>
