MSN Username issue?

I have a user that has a username as

For some reason I cannot get her to log on - she keeps getting “The password you registered with is incorrect. Please re-register witht he correct password” (whether I register throught the client or the server)

She can login into msn, windows messenger, msn messenger, and live messenger without a problem - so I know the password and account are fine.

But I can’t seem to figure this out!

Old request but if its still an issue:

Check the length of the password. Openfire seems not to be able to handle MSN-Passwords with more than 16 chars, wich results in a wrong password.
