Per usare piu di uno LDAP server oppure piu di uno userBase dello stesso LDAP server, in /opt/tomcat8/conf/Catalina/localhost/ creare un file DocWay4.xml con questo contenuto:

<?xml version='1.0' encoding='utf-8'?>
<Context displayName="DocWay4" path="/DocWay4" privileged="true" workDir="work/Catalina/localhost/DocWay4">
 
<Realm className="org.apache.catalina.realm.CombinedRealm">
        <Realm className="org.apache.catalina.realm.JNDIRealm"
                connectionURL="ldap://192.168.92.140:389"
                connectionName="CN=Ldap,CN=Users,DC=esempio,DC=it"
                connectionPassword="password"
                referrals="follow"
                userBase="OU=altri,dc=esempio,dc=it"
                userSearch="(sAMAccountName={0})"
                userSubtree="true"
                commonRole="jspuser" />
 
        <Realm className="org.apache.catalina.realm.JNDIRealm"
                connectionURL="ldap://192.168.92.140:389"
                connectionName="CN=Ldap,CN=Users,DC=esempio,DC=it"
                connectionPassword="password"
                referrals="follow"
                userBase="cn=Users,dc=esempio,dc=it"
                userSearch="(sAMAccountName={0})"
                userSubtree="true"
                commonRole="jspuser" />
 
</Realm>
 
</Context>
