Hi,
 
When you proceeding the login, the it will also check admin user's domain name. if the domain name you set is different with the domain name of you machine, it will be failed.
 
Suggestion:
 
1. check the domain name field in the subscriber table, for example, it is "my.domain.com"
2. edit /etc/
add an entry:
 
your_IP_address                    my.domain.com    my
 
 
then reboot your machine, this problem should be resolved.
 
good luck.
 
BTW, I have a question: did you get the error messages like this? it seemed like can not found  "prolog.html". I wonder how can i resolve this problem
