[Dovecot] Dovecot 1.2, problem with SQL quota and mail aliases

[Tomislav Mihalicek]

I have the same problem but with LDAP, how to fix this on LDAP backed?

scope		= subtree
deref           = never
pass_attrs      = userPassword=password
base		= ou=accounts,dc=globalnet,dc=hr
user_filter     =
(&(|(objectClass=qmailUser)(objectClass=mailUser))(accountService=mail)(accountService=%Ls%Lc)(|(mail=%u)(mailAlternateAddress=%u)))
pass_filter     =
(&(|(objectClass=qmailUser)(objectClass=mailUser))(accountService=mail)(accountService=%Ls%Lc)(|(mail=%u)(mailAlternateAddress=%u)))
pass_attrs      = userPassword=password
default_pass_scheme = MD5
user_attrs      = homeDirectory=home,mailQuotaSize=quota_rule=*:bytes=%$
