[turba] IMAP full domain auth with ldap user lookup?

[Greg Wilson]

Using Horde Groupware 1.0, with mysql storage
 
Users authenticate to IMAP using full email address. Can someone explain how to setup hooks to do an ldap or MYSQL lookup so Horde then uses correct name?
 
eg. login: bbloggs at anywhere.com
 
lookup bbloggs via MySql or ldap
 
Horde displays Billy Bloggs as user name
 
At present Horde displays email address & I have to get all users to enter their correct name into IMP so their emails are sent with real name<email at address.com>.
