[SM-USERS] SM with Exchange on IIS -- Almost working!!! (need help though)

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

I almost have this working.  It logged in twice now somehow.  I was able to 
send a recieve mail and everything.  But I can't seem to get it to log in 
again (I didn't change anything between logins either).  Here is what I get 
when I try to log in with PHP warnings OFF:

-----[begin]
Bad request: Protocol Error: "Provided username is not valid".
Read data:
-----[end]

now that I'm pretty sure this an error from the IMAP server.  Look at the 
next thing I have though and I think it explains this error.  I think SM of 
PHP is doing something to 'lose' the username vaiable.  When I try to og in 
with PHP warnings ON:

-----[begin]
login:
Notice: Undefined variable: username in 
c:\inetpub\wwwroot\mail_new\src\webmail.php on line 39
Notice: Undefined variable: username in 
c:\inetpub\wwwroot\mail_new\src\webmail.php on line 44
Notice: Undefined variable: username in 
c:\inetpub\wwwroot\mail_new\src\webmail.php on line 49
Notice: Undefined variable: username in 
c:\inetpub\wwwroot\mail_new\src\webmail.php on line 50
-----[end]

if I hit the back button and try again i get a framed page with this:

-----[begin]
(left frame)
Notice: Undefined variable: key in 
c:\inetpub\wwwroot\mail_new\src\left_main.php on line 201

(right top frame)
Notice: Undefined variable: key in 
c:\inetpub\wwwroot\mail_new\src\right_main.php on line 40

(right bottom frame)

SquirrelMail version 1.2.6
By the SquirrelMail Development Team
ERROR
Unknown user or password incorrect.
Go to the login page
-----[end]

if i go to the login page using that link i start over with getting the 
non-framed page of warnings again.

Does anyone have any idea why it is doing this?  It seems like it would be 
php's fault in losing the variables but I dont know php.  And why the heck 
would I have actually been able to login twice?  Another tidbit of useful 
info is even when I do get the errors it _DOES_ actually log in to the 
exchange server is seems.  I have the logging turned on pretty high on the 
exchange server.  Whenever I make an attempt to log in via SM it puts a line 
in my even log that I succesfully loged on to the information store.

any help would be greatly appreciated.  I know this has to work now that I 
actually logged in!

running php 4.2 with SM 1.2.6, below is my config.php and most of the 
php.ini settings

thanks,
matt
