I ran into problem when trying to view the deployed apps on the tomcat server.
When i tried to view the web applications i was prompted to enter a user name and password in the Authentication
Required dialog.
When i clicked cancel i was told that i can use the Tomcat customizer in the Servers manager to set the correct username
and password for manager role.

I open Servers manager and I see the tomcat user name and change the password. I click Close.
I restart Tomcat.
I try to view deployed applications in Services window and i see the same Authentication Required dialog.
I type in the username and new password.
Dialog closes and reopens again prompting for username and password.
I look in customizer and the user and pw are the new user and pw that i typed. 

There is no way to view the deployed apps.
There is no way to set the username and password.
The username and pw fields in the Tomcat customizer do not seem to do anything.
The panel says that the user and pw are the credentials of existing user in manager role, but modifying the fields does
not appear to create a user or modify a password.
So either the tomcat customizer is broken, or the wording of customizer and dialog are incorrect, or both.


If i look in tomcat-users.xml in my userdir i can see a user and pw for manager role and if i use that i can view the
deployed files.
