I don't believe this is a ticket cache problem. I'm guessing slapd/sasl has
access to your cache, just not one which contains
ldap/[email protected]. I assume that the wrong service principal is
being requested, which you should see in your kdc logs corresponding with
an entry that it's not found in the database.

slapd should pass the serverFQDN in it's call to sasl_client_new, which
should ultimately result in a request for ldap/serverFQDN towards the kdc.
If you're not seeing anything useful in auth.debug, try increasing slapd
logging on the consumer.

Can you connect to the provider, from the consumer, over GSSAPI using ldap
client tools?
