Hello all...

Easy question...
Can you call UCM Web Services anonymously? Basically with "guest" rights? If so, any examples how...? I'm using VB.NET

More complicated question and advice seeking...
I am trying to create an ASP.NET form that will send an email with a content item as an attachment. I was going to attempt to use the web services to get the document info and actual files, and then use ASP to fire off the email. The user will either be logged into our site with (ExtranetLook component) valid credentials, or be viewing the site as guest/anonymous. As far as I can figure, I can only call the web services if I have some kind of authentication... I cannot call it w/o any auth, and I cannot somehow pass in the currently logged in users authentication credentials to the service... I really need to know the username/password, or use Windows Authentication (which is not possible on this public site). Any suggestions for how I can get around this problem?

Thanks,
Dave
