auth process should log an error about this too?
It does? I guess we do not have that enabled. Only have these two set:
log_path = /var/log/dovecot_error.log
info_log_path = /var/log/dovecot_info.log
Perhaps you mean I should enable "auth_verbose" ? That I can do.
This is all handled by OpenLDAP code internally. I've no idea how it works.
Ah yes, I see that you just pass "LDAP hosts" directly to ldap_init().
So it really is up to LDAP there.
src/auth/db-ldap.h :
/* Maximum number of pending requests before delaying new requests. */
#define DB_LDAP_MAX_PENDING_REQUESTS 128
That's probably too large, because for v2.0 I've dropped it to 8:

Yeah, by default slapd starts 16 threads, but only half of those are allowed to
