[imp] IMP-PHP random login

[javi marcos]

Hi, I've searching this in the mailing lists but I'm not lucky.

packages installed (all by rpm)
- imp3.0.1
- horde 2.0.1
- php4.1.2-0horde1
(from www.horde.org)

-php-mysql
-php-imap
-mod_ssl
-mod_php
-mod_php
-apache
-mod_perl

the problem is that in the login.php page of IMP , the login box is
given ,but with different users,for example; sometimes appear frankie,
sometimes alberto,
it seems to be random...

you see it at www.etsetb.upc.es/imp.The same installation and
configuration (except  language and some thngs) is in http or
https;//saigon.upc.es/horde, but in saigon we  have no problem

    Maybe it's an php problem, I don't know, please reply to me and
albert@etsetb.upc.es
