Question

I want to develop an Java application that can detect the user logged on a Windows Domain. These credentials are going to be used to logging on the Java application running on Tomcat.

How can I do this? I want to know the remote user accessing my web app. This user is logged on in Active Directory.

Answer 1

This is my solution:

Put jcifs-1.2.7.jar on [TOMCAT_HOME]/common/lib directory.

Modify application’s web.xml adding the followin text to section webapp:

<filter>     <filter-name>NtlmHttpFilter</filter-name>     <filter-class>jcifs.http.NtlmHttpFilter</filter-class>     <init-param>         <param-name>jcifs.http.domainController</param-name>         <param-value>xx.xx.xx.xxx</param-value>  --> Domain Controller IP     </init-param>     <init-param>         <param-name>jcifs.util.loglevel</param-name>         <param-value>2</param-value>     </init-param>   </filter>   <filter-mapping>        <filter-name>NtlmHttpFilter</filter-name>        <url-pattern>/*</url-pattern>   </filter-mapping> 

And the you can get the remote user using request.getRemoteUser() whithout prompt.

See you.
