    Well after rolling back cumulative security patches I found May 9th cumulative security patch is where my LDAP breaks. The patch included in Security Patch for May corrects CVE-2023-28283, My question is there a work around for it or a fix. Here is the error I get after I patch our Domain Controllers..

    Error:
    javax.naming.AuthenticationException: [LDAP: error code 49 - 80090317: LdapErr: DSID-0C090645, comment: The server did not receive any credentials via TLS, data 0, v3839]; remaining name 'ou=xxx,dc=yyy,dc=zzzz,dc=aa,dc=ssss,dc=nnn'

      This issue was fixed for me by the October 2023 cumulative update.
