Hi again:
Sorry, i misunderstood the stack trace below. It appears the TDS is
trying to access a password-protected opendap server, possibly itself?

Dear support,
I'd like to control the access to my datasets (thredds version 3.8.03). I tried
to configure Tomcat Users. Now all seems to works but I can't get ascii data
(after the authentication). I can see an empty web page and and I can read this
error in catalina.out:
OUCH! IOException: Server returned HTTP response code: 401 for URL:

In my ${tomcat_home}/webapps/thredds/WEB-INF/web.xml I added this
security-constraint:
<security-constraint>
<display-name>User thredds</display-name>
<web-resource-collection>
<web-resource-name>thredds allowed</web-resource-name>
<url-pattern>/dodsC/*</url-pattern>

<role-name>thredds</role-name>
</auth-constraint>
<user-data-constraint>
<transport-guarantee>NONE</transport-guarantee>
</user-data-constraint>
</security-constraint>
I'd like to know how to limit data access.
Best regards, Luca
