FIPS mode configuration

LDAP in FIPS mode
You can configure your Microsoft Active Directory server to use LDAP while in FIPS mode. 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 104 lists the differences between FIPS and non-FIPS modes of operation.
Setting up LDAP for FIPS mode
1. Set the switch authentication mode and add your LDAP server by using the commands in the
example below. Provide the Fully Qualified Domain Name (FQDN) of the Active Directory server
for the hostname parameter while configuring LDAP.
Example of setting up LDAP for FIPS mode
switch:admin> aaaconfig --add GEOFF5.ADLDAP.LOCAL -conf ldap -d adldap.local
-p 389 -t 3
switch:admin> aaaconfig --authspec "ldap;local"
switch:admin> aaaconfig –show

FIPS and non-FIPS modes of operation

•
The CA who issued the Microsoft Active Directory
server certificate must be installed on the switch.
•
There is no mandatory CA certificate
installation on the switch.
•
Configure FIPS compliant TLS ciphers [TDES-168,
SHA1 and RSA-1024] on 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
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 by the LDAP client. If the CA certificate is not
present on the switch then user authentication will
fail.
•
If Microsoft Active Directory server is
configured for FIPS ciphers and the switch is in
non-FIPS mode then user authentication will
succeed.
