Imail Web Administration Page SSO. – Stephen's Space on the Web

In my opinion Imail’s Active Directory integration is rudimentary at best. They took the all or nothing approach. The following code is something I wrote to let users logon with their Active Directory account to manage their Distribution Lists. It generates a random password in Imail and then automatically logs them in to the system. The user never knows their Imail password and they think its all connected.

Its also a simple example of HTML form automation with javascript.
