Sonicwall TZ 300 SSL VPN doesn't accept users password after change

My Sonicwall TZ 300, setup for MSCHAPv2, does not allow users to authenticate to the SSL VPN for 24 hours after they update their domain password. I believe that the Sonicwall device is only syncing the password changes once per day which is causing this issue, but I haven't been able to find anywhere in the system settings that would control that behavior. I have noticed this occur when users change their password from within the office and then go home and are unable to connect for 24 hours using the reset credentials.
