[imp] Login Problem with InternetExplorer only

[Volker Main]

Hello,

i have the following magic problem; I hope someone can help me:

I've installed the following components:

- apache 1.3.26
- mysql 3.23.52
- php 4.2.3
- horde 2.2
- imp 3.1


I used the php session handling file based.


I've configured horde for imp single logon in horde/config/registry.php:
$this->registry['auth']['login'] = 'imp';
$this->registry['auth']['logout'] = 'imp';


When I log in with InternetExplorer 5.0 5,5 6.0 with username and password
to the URL http://mywebserver/horde/img
I get the message "Your Mail session has expired. Please login again.".
Then I try it a second time with the same user/password in the same browser
session it works fine.

The horde.log file says:
// first attempt
Jan 29 16:32:28 HORDE [info] [imp] Session timeout for client
[193.254.18.51] [on line 79 of "/var/www/webmail/horde/imp/login.php"]

// second attempt
Jan 29 16:33:38 HORDE [notice] [imp] Login success for vmain at htp-tel.de
[193.254.18.51] to {mail.htp-tel.de:143} [on line 64 of "/var/www/we
bmail/horde/imp/redirect.php"]

If I close the browser and start new I get the same behavier.


If I try the same in Netscape (here v4.6) it works fine.

In IE JavaSkript and Cookies are aktivated. The SessionHandlers in the
tmp-directory appears:

webmail01[admin] # pwd
/var/tmp
webmail01[admin] # ll

Does anyone has an idea or need more information for debugging?
Whats wrong?

Thank You..
