There is no option provided on the switch to configure TLS ciphers for LDAP in FIPS mode. However, the LDAP client checks if FIPS mode is set on the switch and uses the FIPS-compliant TLS ciphers for LDAP. If the FIPS mode is not set and the Microsoft Active Directory server is configured for FIPS ciphers, it uses FIPS-compliant ciphers. Table 88 lists the differences between FIPS and non-FIPS modes of operation. TABLE 88 FIPS and non-FIPS modes of operation FIPS mode non-FIPS mode The certificate of the CA that issued the Microsoft Active There is no mandatory CA certificate installation on Directory server certificate must be installed on the switch. the switch. Configure FIPS-compliant TLS ciphers [TDES-168, SHA1 and RSA-1024] on the Microsoft Active Directory server. The host needs a reboot for the changes to take effect. On the Microsoft Active Directory server, there is no configuration of the FIPS-compliant TLS ciphers. The switch uses FIPS-compliant ciphers regardless of the Microsoft Active Directory server configuration. If the Microsoft Active Directory server is not configured for FIPS ciphers, authentication will still succeed. The Microsoft Active Directory server certificate is validated if the CA certificate is found on the switch. The Microsoft Active Directory server certificate is validated If the Microsoft Active Directory server is configured by the LDAP client. If the CA certificate is not present on the for FIPS ciphers and the switch is in non-FIPS mode, switch then user authentication will fail. then user authentication will succeed. 618 Fabric OS Administrator's Guide 53-1002745-02
