LDAP vs SSO

LDAP and SSO are both used for user authentication but serve different purposes. LDAP is an open protocol for querying and maintaining data in directories while SSO is an authentication method that allows users to use one set of login credentials to log in to multiple apps. LDAP is highly scalable, efficient at read operations, and supports centralized management of identities. However, it can be less efficient when handling a high volume of write operations and requires skilled IT staff for setup and maintenance. SSO offers convenience, increased security, and reduced IT costs by enabling users to access multiple applications from a single place without needing to sign in separately to each app. It also simplifies the task of managing user data and permissions across organizations. However, it can increase vulnerability as there's a single point of failure and added implementation complexity for service providers. LDAP is used to centralize user identities in a structured directory and manage access to all resources within an enterprise network while SSO is used to simplify user access across multiple apps and services.
