Log for a non-working user is attached.

Also here is the userdb-query:

user_query = \
	SELECT 1002 AS uid, 1005 AS gid, '/var/vmail/%d/%n' AS home, \
        IF(imapc,'imapc:','') AS 'namespace/gemeinsam/location' \
        FROM virtual_users \
        WHERE user='%u'

>From the logs it seems that '' is converted to 'yes'.

(So probably, ACL has nothing to do with the error.)
