dovecot - May 2014 - dovecot auth ldap attributes - unused?

Please explain the following dovecot (2.2.13) behaviour: I run dovecot
in ldap auth debug mode and log file excerpt follows:

2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug:
ldap(user at domain,pcip,<bdKvA+P5HQCbnmFI>): bind search:
base=o=tree,dc=do,dc=ma,dc=in
filter=(&(objectClass=MailAccount)(accountActive=TRUE)(mail=user at domain))
2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug:
ldap(user at domain,pcip,<bdKvA+P5HQCbnmFI>): result: mail=user at domain;
mail unused
2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug:
ldap(user at domain,pcip,<bdKvA+P5HQCbnmFI>): result: mail=user at domain
2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: client passdb
out: OK       24      user=user at domain

2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug:
ldap(user at domain,pcip,<bdKvA+P5HQCbnmFI>): user search:
base=o=tree,dc=do,dc=ma,dc=in scope=subtree
filter=(&(objectClass=MailAccount)(accountActive=TRUE)(mail=user at domain))
fields=mail,quota,mailbox
2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug:
ldap(user at domain,pcip,<bdKvA+P5HQCbnmFI>): result:
mailbox=maildir:/mail/domain/user/mail/ quota=1G mail=user at domain;
mail,mailbox,quota unused
2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug:
ldap(user at domain,pcip,<bdKvA+P5HQCbnmFI>): result:
mailbox=maildir:/mail/domain/user/mail/ quota=1G mail=user at domain
2014-05-21T08:22:01+02:00 dovecot/ip dovecot: auth: Debug: master userdb
out: USER     3606315009      user at domain  quota_rule=*:bytes=1G  
mail=maildir:/mail/domain/user/mail/       home=/mail/domain/user

Question: why are there two ldap result log lines while the first line
shows unused attributes and the second doesn't. Does the first occurence
show some code being excessive somehow?

Thanks.

Hello,

no solution but a comment:

ldap.conf define two ldap queries. pass_filter and user_filter

when debugging authentication I use to change my ldap filter:

pass_filter = (whatever) vs. pass_filter = (|(PASSDB=1)(whatever))
user_filter = (whatever) vs. user_filter = (|(USERDB=1)(whatever))

The result is the same, but the debug log is easier to understand.
