I have the same problem on my webmail IMP, I want logon (from PC) 
using IMP and (from Mobile) using MIMP, and I solved my problem just 
editing the  MIMP/conf/conf.php.

My horde is configured with $conf['auth']['params']['app'] = 'imp'; 
IMP makes the authentication, then I edit MIMP/conf/conf.php and put 
that line:



$conf['auth']['params']['app'] = 'mimp';



When someone try to logon by my MIMP url then that variable turn MIMP 
my auth application.

No feedback.

initial_application should be ignored for any mobile devices, and in 
fact my wap phone works fine, no matter which initial application I set.

It's more likely that the first user agent is not detected as a mobile 
device in lib/Horde/Browser.php. The infinite loops seems to be a 
different problem though.

Most likely your initial_application pref is 'imp'.  It should really 
be 'horde' for this kind of situation.



Although now I say this, I think to myself that 'imp' is my 
initial_application pref but MIMP seems to work fine for me.  I never 
access MIMP through a WAP gateway however - my only test bed is my PDA 
via plain old 802.11 tcp/ip wireless connection.



If it is initial_application that is the problem we probably need to 
override this with a preference in MIMP's prefs.php (or through some 
other means) that allows us to define 'mimp' as the 
initial_application when using MIMP authentication.

Me again, i want to add few more info.



I've tested my IMP/MIMP http://clients.ooline.fr install with another 
WAP phone emulator ( Openwave )



The error message is differents:

"Request exceeded maximum number of redirect."



So, it seems that the issue is due to a looping redirect...  Like IMP 
and MIMP ping-ponging together, and sending the client to eachother...

Hi,

I'm using brand new version of Horde, Imp and Mimp.

I followed exactly the instruction on how to use "composite" 
authentication for using both IMP or MIMP depending device.

( http://wiki.horde.org/display.php?referrer=HowTo&page=MIMPHowTo )



But, when i access my install ( http://client.ooline.fr OR 
http://client.ooline.fr/mimp/ ) with a WAP browser ( Klondike ), i'm 
always redirected to the IMP login page.



Then of course, WAP browser do not recognise content return but IMP...



I get a "there was too much data received" error message.



Is it a know issue ? Is it due to this WAP emulator ?



Thanx
