terminal - 401 Unauthorized error while logging in Manager-App of Tomcat

Question

I am trying to log in to the Manager App in Tomcat 7.0.22 for Mac OS X 10.7. Here is the error I am getting: http://f.cl.ly/items/421q1K3f1i0X1H1M181v/so.tiff

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"/>

I have added this in my tomcat-users.xml, still its not taking the same username/password.

<tomcat-users>
<role rolename="manager-gui"/>
<user name="tomcat" password="s3cret" roles="standard,manager-gui"/>
</tomcat-users>

Answer 1

OK, I had this error too. Couldn't find the bug, couldn't find the bug, couldn't find the bug. My "tomcat-users" block looked just like this.

<tomcat-users>
<role rolename="manager-gui"/>
<user name="tomcat" password="s3cret" roles="standard,manager-gui"/>
</tomcat-users>

FINALLY FOUND THE BUG. I kept editing the XML inside the XML comment block:

<!--
<tomcat-users>
<role rolename="manager-gui"/>
<user name="tomcat" password="s3cret" roles="standard,manager-gui"/>
</tomcat-users>
-->

DOH!

So: don't forget to remove the "<!--" and "-->".
