Tomcat Manager - Active Directory Authentication

Question

I want to know how it's possible to use Active directory, for access roles on tomcat manager app?

The idea is to make possible accees to http://localhost:8080/manager application for specific LDAP Group.

I browsed the net, but ahven't find a complete solution.

Best regards

I found solution; I had created a JNDIRealm t ask my AD for authentication

      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.JNDIRealm" 
             debug="99"
             connectionURL="ldap://LDAPSERVER:PORT"
             connectionName="LDAP_USER"
             connectionPassword="LDAP_PWD" 
             adcompat="true"
             referrals="follow"
             userBase="OU=Users,DC=company,DC=com" 
             userSearch="(sAMAccountName={0})"
             userSubtree="true"
             userRoleName="memberOf"
             roleBase="OU=Groups,DC=company,DC=com"
             roleName="cn" 
             roleSearch="(member={0})" 
             roleSubtree="true"
             roleNested="true"
             authentication="simple"
             />
    </Realm>

Then, I modified the web.xml of my tomcat Manager application, the idea is to add the desired AD Group that should have access to the application:
