AD SSO and Basic User Authentication in one network

Hi,

I'm migrating a customers network from Standard Proxy with Basic User Authentication to Active Directory with SSO.

Thanks to Bob's howto in the knowledgebase it was easy to get AD SSO to work, but I struggle to get both methods working during the migration process.

I made two proxy-profiles: StandardProxyUsers and ADUsers.

But depending which profile is first, this one is working and no fallback to the other.

When I put ADUsers-profile first the standard user are promted for authentication but because the user is not known to the AD database, they are blocked and prompted endless.

When I put the StandardProxyUsers-profile first, they can authenticate, but the AD users are blocked.

I could not find a way to point ADusers to profile 1 und StandardUsers to profile 2, such as a fallback if it's not an ADUser goto profile Standard.
