What's wrong with this SOAP header?

Question

Greetings. I'm trying to update our application to support the v6 API, but I'm getting authentication errors ( when using credentials that work fine with v5.1 API ).

Our SOAP header looks like this ( with credentials and stuff removed ):

<SOAP-ENV:Header>
    <DeveloperToken xmlns="https://adcenter.microsoft.com/api/advertiser/v6">xxxxx</DeveloperToken>
    <CustomerAccountID xmlns="https://adcenter.microsoft.com/api/advertiser/v6">666</CustomerAccountID>
    <CustomerID xmlns="https://adcenter.microsoft.com/api/advertiser/v6">666</CustomerID>
    <ApplicationToken xmlns="https://adcenter.microsoft.com/api/advertiser/v6" xsi:nil="true"/>
    <Password xmlns="https://adcenter.microsoft.com/api/advertiser/v6">xxxxx</Password>
    <UserName xmlns="https://adcenter.microsoft.com/api/advertiser/v6">xxxxx</UserName>
</SOAP-ENV:Header>

We're getting the error:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body><s:Fault><faultcode>s:Client</faultcode><faultstring xml:l
ang="en-US">The creator of this fault did not specify a Reason.</faultstring><detail><AdApiFaultDetail xmlns="https://adapi.micros
oft.com" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><TrackingId>6e939b54-1f28-4917-a2a7-6e0513735284</TrackingId><Errors>
<AdApiError><Code>105</Code><Detail i:nil="true"/><ErrorCode>InvalidCredentials</ErrorCode><Message>Authentication failed. Either 
supplied credentials are invalid or the account is inactive</Message></AdApiError></Errors></AdApiFaultDetail></detail></s:Fault><
/s:Body></s:Envelope>

Any ideas?

Doh! Wrong namespace. I trusted some other developers who'd bumped our ref data to actually get it right. They didn't. Sorry for the noise.
