CentOS - Nov 2009 - problem with stable version of roundcubemail contained in the depot Karanbir Singh

Hi all
Hi list


my linux box is CentOS 5.4
it is properly updated
I use the [root at r13151 ~]# rpm -qa | grep roundcubemail
roundcubemail-0.2.1-1.el5.kb
[root at r13151 ~]# 
 roundcubemail , which is contained 
in the deposit karanbir singh
I preferred to continue using the version contained in the official (depot 
karanbir singh its offcial repositories yes or not )
repositories of CentOS

I use postgresql
This is correctly configured as described in the INSTALL file

I use the standard PHP of Jason's Utter Ramblings Repo (http://fakessh.eu/
it
is the 
phpinfo(); page )

my problem is that
?I see appear the login page (http://fakessh.eu/roundcubemail )
I enter all data but I do not 
understand why I can not fit into the webmail
the logs directory is empty

when I use the url  
http://fakessh.eu/roundcubemail/?_task=&_action=login 
with the correct username and the correct password, 
the page shows me an authentication error

when I use the url 
http://fakessh.eu/roundcubemail 
with the correct username and the correct password, the page tells me no 
errors

thanks for all your feedback
