[imp] Mimp Login Failure problems

[Rory McKinley]

Hi List

We have recently implemented Mimp on our Horde Groupware setup. It;s 
working like a charm, with just one slight hitch:

If the mobile user's login fails, they get redirected back to a login 
screen. Unfortunately, when they login again, this time with the correct 
credentials, Imp does not appear to correctly identify them as mobile 
users and so they are routed to the DIMP interface... and much hilarity 
ensues!

I am sure that this is just a config setting that we are missing - can 
anybody give me some idea of what I need to set so that the users are 
always correctly identified as mobile users?

Thanks in Advance

Rory
