[horde] Horde with LDAP auth and e-mail as IMAP username

[Ivajlo Karabojkov]

Hi,

I'm trying to set up a Horde with LDAP authentication and user management.
Each mail domain should have its own horde configuration and users log 
in with their username (cn). But the IMAP server works in "virtual 
users" mode and expects as an username the e-mail address, consisting 
the username (cn)+"@"+domain.com.
Is it possible to configure IMP to send the whole e-mail address as an 
username to the IMAP server without asking users to enter it as username?

Best regards,
Ivo
