[Dovecot] Prefetch help

Hello,

I am trying to use userdb prefetch so that I don't do an extra LDAP

lookup and I am having some problems:

Here is my dovecot-ldap.conf # cat /etc/dovecot/dovecot-ldap.conf hosts = 192.168.50.30 192.168.50.31 base = ou=HST-Users,dc=h-st,dc=com ldap_version = 3 auth_bind = yes dn = cn=ldap,cn=Users,dc=h-st,dc=com dnpass = <PASSWORD> user_attrs = sAMAccountName=mail=maildir:/home/vmail/%Ud/%Ln/Maildir/,=gid=1000,=uid=1001 user_filter = (&(objectClass=person)(mail=%u)) #pass_attrs = sAMAccountName=mail=maildir:/home/vmail/%Ud/%Ln/Maildir/,=gid=1000,=uid=1001 pass_filter = (&(objectClass=person)(mail=%u))

This works just fine and it only authenticates if the user's email field has an email address, which is what I want.

But I cant get it to work with prefetch. How could I accomplish that..?

Thanks
