I've found a strange authentication problem using SecurId and Outlook Web
Access (OWA) on windows 2k in a client company.

this is the normal procedure for reading the OWA mailbox:
- SecurId Authentication, RSA token, username, pin
- Logon page for OWA
- OWA Authentication using username/password
- Read mail

This is what i do normally, and it works fine. However when i disconnect and
then reconnect using a different OWA account on the OWA Authentication page
i get the following error :

"Your NT username (xxxxx) does not match your SecurID username (yyyyy)."

When i then reload the error page multiple times i eventually get access to
the mailbox of (xxxxx).

I do not need the SecureId pass of the second NT user to get access, only
the OWA password.

Microsoft and SecurId was informed
