This error message is returned by LDAP server. See if there is any configuration related to this on server side.
We are authenticating against sun directory server yet see no errors in the directory server and it seems to be under low load. Any ideas if there is something on dovecot we should tune to erradicate this?
You could try if increasing auth process count helps (but that could also break startup in some setups):
auth default { .. count = 5 }
