The Authentication Configuration panel contains separate tabs for RADIUS, Active Directory
(AD), TACACS+, and CAC configuration. Select the appropriate tab to configure one
of these authentication options.
To secure information passed during authentication, you can enable SSL-based encrypted
communication between the SMS and an AD authentication server, and you can import
an x509 certificate from a RADIUS server to the SMS. The SMS server accepts DER (binary)
or PEM (Base64) encoded x509 certificates. TACACS+ servers do not use SSL-based encryption
or certificate-based authentication.
To edit authentication configuration, your user account must be a member of a group
with superuser role capabilities or the
SMS Authentication and Authorization Admin capabilities.
