Splunk Enterprise SAML integration
Multi-factor authentication (MFA) is an extra layer of security used when logging into websites or apps to authenticate users through more than one required security and validation procedure that only you know or have access to.
Security Assertion Markup Language (SAML) is a protocol for authenticating to web applications. SAML allows federated apps and organizations to communicate and trust one another’s users.
Arculix™, as a SAML provider, improves the user login experience for Splunk Enterprise users with its smart and convenient single sign-on (SSO) MFA.
Prerequisites
Configured Arculix instance and user account with administrative privileges for Arculix.
Configured Arculix LDAP Agent.
For more information, see the Arculix LDAP Agent deployment guide.
