> 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)}
