My question is with regard to an error that I get on an OpenLDAP consumer server that uses Kerberos to authenticate to a provider:

Check your kdc server logs to verify the service principal the consumer
is requesting, which appears to be incorrect.

auth.debug in your syslog, on the consumer and provider, may provide
additional information.

Do you have some other component in your consumer configuration which
references localhost?

There's a Kerberos key table with keys for an ldap/ principal that's used for slapd and k5start is used to to maintain the Kerberos ticket cache for it. That all works fine.

Furthermore, the hostname for the system, srv4, is configured correctly, there's almost nothing in /etc/hosts (just ' localhost' and a few IPv6 linklocal lines), and the forward and reverse DNS entries for this host all refer to (for IPv4 and IPv6).

Alas, nothing seems to make a difference and slapd insists on authenticating itself to the slapd provider as ldap/localhost@xxxxxxxxxxx, which doesn't work.

Could this be a bug? If so, this there a workaround?
