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 cache miss mail.debug: Jul 29 12:45:28 dovecot: auth: Debug: ldap(blätula): user search: base=ou=users, dc=uma,dc=local scope=subtree filter=(&(objectClass=inetOrgPerson)(uid=blätula)) fields=uid,uid mail.debug: Jul 29 12:45:28 dovecot: auth: Debug: ldap(blätula): result: uid=BLÄTULA; uid unused mail.debug: Jul 29 12:45:28 dovecot: auth: Debug: ldap(blätula): result: uid=BLÄTULA mail.debug: Jul 29 12:45:28 dovecot: auth: Debug: userdb out: USER 1 blätula home=/var/data/vmail/private/blätulaspuser=private/blÄtula

hi all,

I encountered some problem with lowercasing chars like an "Ä"

with user_attrs like this:

user_attrs = uid=home=/mail/%Lu, =myvar=%L{ldap:uid}

the Ä doesnt get lower cased in both cases

# doveadm user BLÄTULA field value user blÄtula uid vmail gid vmail home /mail/blÄtula mail maildir:~/Maildir:LAYOUT=fs:INBOX=~/Maildir/INBOX myvar blÄtula

somebody knows if there a fix for that?
