have a web service using wse 3.0, usernameforCertificateSecurity, and a
custom usernametokenmanager.  If I run the web service and a client on my dev
machine it works fine,  but now I have moved the web service to another
machine and wse is puking on me.

I have the certificate set up correctly.



The error I'm seeing in the server event log is:

...

System.Configuration.ConfigurationErrorsException: The entry 'UsernameToken'
has already been added.

...



My web.config looks like this:

<microsoft.web.services3>

<policy fileName="wse3policyCache.config" />

<security>

<securityTokenManager>

<add type="XXXXX.Common.ServiceSecurity.ServiceUsernameTokenManager,
XXXXX.Common.ServiceSecurity"
namespace="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" localName="UsernameToken" />

</securityTokenManager>

</security>

</microsoft.web.services3>

This is the only place in my web.config where 'UsernameToken' appears.  

I saw a single posting on a message board somewhere by someone having the
same issue.  In his case he said there were some wse 3 config files sitting
in wwwroot that he had to delete.  I don't seem to have those files so
unfortunately that information does not help me.

I've tried adding a <clear/> command before doing the <add> but I still get
the same message.  



Anyone have any ideas why my web service is failing on processing the config
file?
