AD web app integration and VPN

[Guest]

Greetings!

I'm by no means an expert here, but nobody on my staff can help so am trying
to see if anyone has seen this.

We current have 2 completely separate web applications that are integrated
with Windows security so if I go to either web site, I'm automatically logged
in using the credentials I logged into our network with.

When our users were out of the office on our company VPN and would go to
these web sites, once again they would be logged in automatically.

Just recently both of these web sites started requiring our users to login
with their network credentials when they visit these sites while on VPN and
required them to put a domain in front of their username. They are still
auto-authenticated when on our LAN, but not on VPN for some reason. We
haven't changed anything with our VPN so am wondering if something got
changed within our network to cause this.

Now the kicker is if I go to a user's PC and add both of the web site
domains I speak of to the TRUSTED SITES section of Internet Explorer, they
DON'T get prompted to login on VPN anymore when off our LAN. Have tested this
with 10 different people, same result.

So, am wondering if anyone knows the situation I speak of and based on how I
get around it by adding these domains as TRUSTED sites in IE, why it may have
started requesting authetication while on VPN and why adding the domains to
that area in IE straightens it out when they are on VPN.

Any help much appreciated!!!!

Thanks!

Hey Rich,

If you look at the bottomof Internet Explorer, it displays what zone you
are currently in when accessing the web sites. What is does the zone
state? My guess is it probably is remaining with Internet, which is
probably the reason you are receiving the prompt.

The other thing to check, is did anything change in your IIS Directory
Security for the applications that you company uses? This could be the
other reason you are seeing the prompt.
