actually good question. I have to admit I only use LMTP and for that it
works for me.
I left out some more settings which might be important for you:
pass_attrs = uid=user
user_attrs =
uid=user,=uid=600,=gid=600,=home=/srv/dovecot/%n,suseImapQuota=quota_rule=*:storage=%{ldap:suseImapQuota}M

since obviously the search itself it not sufficient. You need to make sure
that the right mailbox is addressed in the end via the uid=user
In your configuration you do not return a user at all so this can be a
problem IMHO.
