By the way LDAP auth:

We have serious problem with LDAP auth in Dovecot before rc18 or such:
though it turned out it sould be an OpenLDAP problem instead (but we can't
change the server). I've got an own stretch test, which does quite large
amount of POP3 sessions in paralell: before rc18 only after some seconds,
some fault was occured and dovecot auth starts blocking further requests.
I've tested rc22 some days ago: I can't detect a single failure anymore :)
