Claims-based authentication relies on standards such as WS-Federation and WS-Trust. Although this problem is rare, it is difficult to diagnose because the error messages are vague. In this book, you will gain extensive hands-on experience installing and configuring a firewall. Users are unable to authenticate via Kerberos (Negotiate). Previously, a Kerberos-capable build of libpq would use the principal name from any available Kerberos ticket as default database username, even if the connection wasn't using Kerberos authentication.

For example, if there are 2 kerberos realms A and B, the cross-realm trust will allow the users from realm A to access resources (services) of realm B. Then run NLTest /DCList to get a list of DCs for the domain. Claims authentication is recommended for all SharePoint Server web applications. This can affect the planning and design of domain boundaries. During authentication, Kerberos stores the specific ticket for each session on the end-user's device. Yes. You can use NLTest /SCVerify for that. The Kerberos protocol supports an authentication method that uses tickets that a trusted source provides. Kerberos is a network authentication protocol which also provides encryption.
