Installing Horde Issue

Hi,
this is my first post so im not sure if it's in the right place.
Btw i have installed horde throught some guides i found on this forum, but i hae still an issue.
I cannot login after i completed the setup, in deed, the user table in horde DB is empty.
How can i import users from directadmin?
Thank you so much if someone can help me.

Why would you import users? It should authenticate through imap.

Ok, thank you, i have installed imp to handle the login, is this right?
