Using top-down-order and / as separator is the standard behaviour of OpenSSL.
:-/ One can also display subject and issuer names in certs with
openssl x509 -nameopt rfc2253

Since this is about GRID services I guess someone falsely put a Kerberos
service prinicipal name in the CN attribute of the server cert. The cert has
to be corrected to contain exactly the FQDN of the server used during LDAP
connect *without* the prefix "host/".
