[imp] External authentification problem

[Cedric Tardif]

Hi all,

I have a website that is at www.mydomain.com and horde/imp that is installed as mymail.mydomain.com

If i go to mymail.mydomain.com and log in my mail account all work fine.

I have created a login menu on my webpage on www.mydomain.com so user can access to there mail by authentificating on www.mydomain.com but when i do so i get this error message :

déc 24 08:20:02 HORDE [notice] [imp] Login success for cedrict at mydomain.com [x.x.x.x] to {mail.mydomain.com143} [on line 82 of "/mnt/sda5/www/horde2/imp/redirect.php"]
déc 24 08:20:15 HORDE [error] [imp] FAILED LOGIN x.x.x.x to mail.mydomain.com:143[imap/notls] as cedrict [on line 164 of "/mnt/sda5/www/horde2/imp/lib/IMP.php"]

Anyone have a idea how to correct this problem ?
