             Summary: Empty password prevents preemptive authentication headers 
from being sent
                 Key: MTOMCAT-151
                 URL: https://issues.apache.org/jira/browse/MTOMCAT-151
             Project: Apache Tomcat Maven Plugin
          Issue Type: Bug
          Components: commons-lib
    Affects Versions: 2.0-beta-1, 2.0
            Reporter: Peter lynch
            Assignee: Olivier Lamy (*$^¨%`£)


Default username for auth is *admin*, default password is "" ( empty string ).

Problem is when password is empty string, TomcatManager.java does not send auth 
headers, so deploy and deploy-only goals fail with 401 after appearing to 
upload the war successfully.

Seems to have been introduced by 
[this|http://svn.apache.org/viewvc/tomcat/maven-plugin/trunk/common-tomcat-maven-plugin/src/main/java/org/apache/tomcat/maven/common/deployer/TomcatManager.java?r1=1178619&r2=1212685&pathrev=1301824&diff_format=h].

The line in question is 171 of which decides what to do about auth.

{noformat}
if ( StringUtils.isNotEmpty( username ) && StringUtils.isNotEmpty( password ) )
{noformat}


Workaround: set a non-empty password for the user accessing /manager/text.

Expected: blank password to trigger preemptive auth headers.

{noformat:title=Proof that TomcatManager didn't send auth headers pre-emptively 
for empty password(default)}
