ldap attribute modifiers. how to lowercase non ASCII

[matthias lay]

update of investigation...

I encountered a different behavior in %Lu and %L{ldap:uid} when doing
the search with lower cased user.

# doveadm user blätula

field	value
uid	vmail
gid	vmail
home	/var/data/vmail/private/blätula
mail	maildir:~/Maildir:LAYOUT=fs:INBOX=~/Maildir/INBOX
spuser	private/blÄtula


so in this case. the name gets lowered in the %Lu but not the
%L{ldap:uid} case.

- The user in ldap is all upper case.
- system locale is en_US.UTF-8


log of the above doveadm query:


mail.debug: Jul 29 12:45:28 dovecot: auth: Debug: master in: USER	1
blätula	service=doveadm
mail.debug: Jul 29 12:45:28 dovecot: auth: Debug: ldap(blätula): userdb
