I'm using WebVPN on an ASA5510 with software7.1 and Outlook Web Access (Exchange 2003).
Everything was working perfectly where someone could log into the WebVPN home page and there was a link to OWA. Clickig on that link would bring you to the OWA login prompt (encapsulated in a cisco login page) which would log you into OWA. It was working fine. However over the last couple days, logging into OWA immediately takes you to the WebVPN logged out page. This is very bizarre because nothing changed. OWA still works perfectly from the Intranet and the other websites and cifs links still work fine from WebVPN. It's just that logging into OWA from WebVPN logs you out of WebVPN. Happens with IE6, 7, and Firefox and to everyone all of a sudden.
