Some users tell us that "I get a message that tells me that (the password) does not match the one that appears in Windows".
If you find yourself in this situation, you probably said (at the time) 'YES' when Windows proposed you to keep the password. That's an option we don't recommend (not only with IMI but generally): when you tell a machine to learn your password to some extent you're reducing its security since anyone who accesses that machine just by knowing or guessing -easy- your username will be able to 'bypass' the password. Thankfully, IMI additionally asks to know three of the 12 letters of a secret code.
If you said 'yes' to that proposal that Windows offers you, the most sure thing is that the password you have saved is the first one you used (the temporary one) that is not the definitive one that later has to be changed to a definitive one). Since the definitive password is not that temporary, the conflict occurs (the password that the system remembers and writes automatically is not the correct one).
There are two solutions:
1) Tell Windows to forget that password that has been learned (this can cost a bit, better contact your organization's computer to guide you)
2) When the 'do not match' message comes out, a 'do you want Windows to replace the password you have saved with the new one you just typed? '. Answering yes, it will memorize the new password (make sure you have typed it correctly)
Our recommendation would be that you opt (sooner or later) for the first option and write the memory password on each access.
The other is an attempt by Windows to make life easier for its users. Security is never comfortable, and we have to get used to giving up the convenience of not having to write a password if we guarantee better security conditions in return.
