Had the same problem. Created a header with soapUI.
Unfortunately I am only allowed to post URLs to other sites after a have made 15 posts or more.
So I replaced http colon slash slash with HTTP
<wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="HTTPdocs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
<wsse:UsernameToken wsu:Id="UsernameToken-27777511" xmlns:wsu="HTTPdocs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
<wsse:Username>Bert</wsse:Username>
<wsse:Password Type="HTTPdocs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">Ernie</wsse:Password>
</wsse:UsernameToken>
</wsse:Security>
The password type attribute solved the problem.
