I understands well, I wanted to say that an ldapsearch with the  same
filter as "pass_filter" in dovecot and the same requested field as   
return to me both uid ans password.

pass_filter = (&(objectClass=boursoramaMailAccount)(uid=%u) 
pass_attrs = uid,userPassword

would be the same thing than

$ ldapsearch  '(&(objectClass=boursoramaMailAccount)(uid=mylogin) 
(mailInternalAllowedProtocol=imap))' 'uid' 'userPassword'
(in fact only dovecot's login is able to request userpassword in my  
configuration until dovecot is able to logon as a virtuser to the ldap)

If it's correct it doesn't work for me, I've got Error: auth 
(default): prefetch(mylogin,10.3.245.xxx): passdb didn't return  
userdb entries

Agree you?
