I have an IIS server on Win2008R2 behind a router, setup to accept remote and intranet access including Outlook Web Access (OWA)
All works fine and an authentication prompt occurs upon first access from browser. (both http and https)
This then displays a basic menu page (default website port 80/443) with links to other websites/Applications hosted on the same IIS server on different ports. Some are in different AppPools but all use same integrated pipeline mode and Identity.
But attempting to open the linked site throws another Login request. Enter the same credentials and the site opens correctly. Including OWA.
"Windows Authentication" is the only type enabled for the relevant sites in IIS. Providers are NTLM and Negotiate, in that order for all sites.
not a big deal from a browser with keyboard but users are complaining when using tablet or phone browsers due to typing requirement.
'Default Website' is in DefaultAppPool http:80
'Content' is in ASP.NET v4 Default, https: *.4438
both https certificates are the same GoDaddy valid till 2016
Any hints to try ? cant do anything too fancy in testing as all sites live and working...
