Single Sign-On(SSO)

• Authentication process allowing users to access multiple applications with one set of credentials
• Simplifies the user experience and enhances productivity
• Trusted relationship between applications and Identity Providers (IdP)

How SSO Works

• User logs into the primary identity provider (IdP)
• Accesses a secondary application or website configured for SSO
• The secondary application verifies the user’s identity with the IdP’s assertion
• Once authenticated, access to the secondary application is granted

Benefits of SSO

• Improved user experience
• Increased productivity
• Reduced IT support costs
• Enhanced security, encouraging stronger passwords

Protocols for SSO

LDAP (Lightweight Directory Access Protocol)

• Used to share access and maintain distributed directory information
• Can share user information across network resources
• Supports central repository for authentication and authorization
• Can be secured using LDAPS (LDAP over SSL or StartTLS)
