Hi,
  I am using Usernametoken authentication with WSE 3.0 to check the user
credentials against the database, but I am getting the following error message

Security requirements are not satisfied because the security header is not
present in the incoming message

actually I didn't implement the validation of the password, I am just
returning the password inside the authenticationtoken class like this.
   protected override string AuthenticateToken(UsernameToken token)
   {
       return token.Password;
   }

I added security token manager to the webservice and added a policy. while
adding policy, I left authorization unchecked and checked the box for
security extensions and unchecked the establish security session and selected
the certificate WSE2QuickStartServer and clicked finish finally. did the same
for client.
   since I am not using the default windows authentication this time, it
should not check the user id and password against windows store. but I don't
know why I am getting this message.

can anybody help me please?

regards,
RK.
