They are the same.
I'm not sure that I understand.
I'm not sure I understand what's going
on either, but the message "Peer
does not recognize and trust the CA that issued your certificate." means
that ldapsearch did not verify your LDAP server certificate
(Server-Cert). This is usually due to one or both of the following:
1) The value of the cn attribute in the leftmost RDN of the subjectDN in
the LDAP server cert is not the fqdn of the LDAP server host, or the
client cannot resolve it.
2) The /etc/openldap/cacerts/cacert.asc CA cert is not the cert of the
CA that issued the LDAP server certificate (Server-Cert)
I'm not sure which one it is. You might try dumping out the server
certificate (../shared/bin/certutil -L -P slapd-server- -d . -n
"Server-Cert" -a > fdscert.pem) and using openssl to verify the cert e.g.
openssl verify -CAfile /etc/openldap/cacerts/cacert.asc fdscert.pem
If you get an error, this means that the CA whose cert is
/etc/openldap/cacerts/cacert.asc did not issue the fedora ds server
certificate.
