Openldap 2.3.27 configured as proxy cache is behaving erratically.
Entries being answered from the proxy cache sometimes result with a negative result, even though the LDAP server has the information.
It appears like the proxycache "forgets" that it has gotten the answer, but doesn't re-query the target server to fetch the information again.
Proxy cache returns 'no such object' for a previously found entry if the ttl has passed between queries:
