Note that this returns "invalid credentials" to users who send their
password unproteced. They may assume they typed the password wrong and
send it unprotected again:-( If you use the 'security' directive
instead, they will get the more informative 'confidentiality required'
However that may stop you from using localhost without TLS too. Haven't
checked. But you can listen for ldapi:// instead.
On some hosts you then won't even need a rootpw:
ldapwhoami -YEXTERNAL -H ldapi://
makes the server pick up the client process' uid and gid. Avoid
ldapi:// on OpenLDAP 2.3.34 and earlier, it has security holes on some

I guess it's an unexpected consequence of how rootdn is implemented.
Access controls are applied to entries, and rootpw is not in an entry.
So an alternative way would be to create an entry with the rootdn as the
DN and rootpw as userPassword, and in slapd.conf keep rootdn but remove
