Horde authentication is done right against the SQL database, not  
against the mail server. User credentials are passed to the mail  
server to initiate an IMAP session; the mail server will check these  
against the same SQL server. This makes user administration easier and  
a Horde session can be created even if the mail server dies.

In fact, SQL authentication should be the most reliable option. Should  
the SQL server die, Horde will be useless anyways.
