Tomcat 7.0.x Manager login problem

I'm trying to access the manager app, but I can't login. I get the logon screen, but when I enter the username and password, the login screen keeps coming back. Any suggestions?

This is what I'开发者_StackOverflow中文版ve done: The manager app is deployed in $CATALINA_BASE/webapps/manager

Part of the server.xml file:

<Resource name="UserDatabase" auth="Container"
  type="org.apache.catalina.UserDatabase"
  description="User database that can be updated and saved"
  factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
  pathname="$CATALINA_BASE/conf/tomcat-users.xml" />
...
<Realm className="org.apache.catalina.realm.LockOutRealm">
  <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
    resourceName="UserDatabase"/>
</Realm>

tomcat-users.xml:

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
  <role rolename="manager-script"/>
  <role rolename="manager-gui"/>
  <user username="tomcat-user" password="tomcat" roles="manager-gui,manager-script"/>
  <user username="tocmat2" password="tomcat" roles="manager-script"/>
</tomcat-users>

In $CATALINA_BASE/conf/Catalina/localhost/manager.xml:

<Context privileged="true"
     docBase="path/to/webapps/manager">
</Context>

Change

pathname="$CATALINA_BASE/conf/tomcat-users.xml" />

to

pathname="conf/tomcat-users.xml" />
