Windows – Tomcat authentification failed – 401 Unauthorized

I have an error when trying to access to Tomcat management console (Apache Tomcat/8.0.50).

WARNING [http-apr-8080-exec-7]
org.apache.catalina.realm.LockOutRealm.filterLockedAccounts An attempt
was made to authenticate the locked user "admin"

I changed configuration file "tomcat-users.xml" and restarted tomcat

<tomcat-users xmlns="http://tomcat.apache.org/xml"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd"
              version="1.0">
<user username="admin" password="!w@B@#7XTFj" roles="manager-gui,admin-gui" />

Information about "realm" in server.xml

<Realm className="org.apache.catalina.realm.LockOutRealm">
        <!-- This Realm uses the UserDatabase configured in the global JNDI
             resources under the key "UserDatabase".  Any edits

        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"

I added loglvel : org.apache.catalina.realm.level = FINE and I have this information:

But it's still impossible to access on console.

Any ideas ?
