DESCRIPTION: Error - 440 Login Timeout While Accessing Exchange 2007 in Translated Mode from Mac OS X
SonicWall support has found that users may get a 440 Login Timeout error while accessing OWA 2007 in translated mode from a Mac OS X machine. This issue has been observed in the following scenario:
Customer migrates from Outlook Web Access (OWA) 2003 to 2007 and has a URL resource configured for both of these servers.
A forms-based single sign-on profile is configured for Exchange 2003, which uses the cookie name cadata.
When the user logs in to WorkPlace and tries to access the OWA 2007 shortcut, the user's browser sends all the cookies set in the browser, including the cadata cookie (which was set for OWA 2003), in the request header.
Because OWA 2007 is specific about the cookie the browser sends, it displays a 440 Login Timeout error to the user.
To resolve this issue, make sure your forms-based SSO profile is configured as described in KB item #4261.
