What is the difference between LDAP and Kerberos?

Kerberos is used to manage credentials securely (authentication) while LDAP is used for holding authoritative information about the accounts, such as what they’re allowed to access (authorization), the user’s full name and uid.

How does Kerberos SSO work?

Kerberos SSO works by having the first application to authenticate (typically a client login process) share the Ticket Granting Ticket it obtains with other applications. This means that the other applications can start with the Ticket Granting Ticket, and do not have to get credentials from the user.

What is the difference between SAML and Kerberos?

Kerberos is a lan (enterprise) technology while SAML is Internet. Kerberos requires that the system that requests the ticket (asks for user identity, in a way )is also in the kerberos domain, SAML does not require systems to sign up before.

Can Azure AD do Kerberos?

To host a Windows Server in Azure that needs to use Kerberos, or for older applications, you would create an Azure Active Directory Domain Services (Azure AD DS) managed domain. This directory synchronises accounts from Azure AD, which in turn can be synchronising accounts from your on-premises Active Directory domain.

Does Azure Active Directory use Kerberos?

The Kerberos delegation flow in Azure AD Application Proxy starts when Azure AD authenticates the user in the cloud. Once the request arrives on-premises, the Azure AD Application Proxy connector issues a Kerberos ticket on behalf of the user by interacting with the local Active Directory.
