can qmail-ldap find out the mail address via the user name (uid)?

["sato x" <gladiol4@gmail.com>]

Hello guys,

I'm building a new qmail-ldap server and going to use the existing ldap
server. All this time, the LDAP server has been used side by side with
a PDC. The problem is, the uid (user login names for the domain) are
different from their email address. For example, my uid=sato but my
mail address is sato.xav@ramona.co.id. 


I can change the uid's according to their email addresses but it will
cost me a lot of work on the implementation, that I have to move user's
profiles from old directory into the new directory (on WinXP Pro). Is
there anyway for the qmail-ldap server to recognize the user email's
password, e.g, when I send an email, the qmail-ldap server will search
for sato.xav@ramona.co.id's password in
uid=sato,ou=Users,dc=ramona,dc

=co,dc=id? Thank you for your help.

Kind regards,

sato
