No credentials cache found while validating credentials 100 dating red flags

By default, SE_CHANGE_NOTIFY_NAME is enabled for all users, but some administrators may disable it for everyone. NTLM’s vulnerabilities and ways of exploiting them are the target of increasing research activity in the security community.

Although Kerberos has been available for many years many applications are still written to use NTLM only.

To have Account Manager launch the interface directly, the caller must supply the current foreground returned by the method (and also passed to the callback).

To make the request synchronously, call and will be passed to the Account Manager Service and to the Account Authenticators.

The uid of the caller will be known by the Account Manager Service as well as the Account Authenticators so they will be able to verify that the package is consistent with the uid (a uid might be shared by many packages).

In some cases, the process that calls Logon User must also have the SE_CHANGE_NOTIFY_NAME privilege enabled; otherwise, Logon User fails and Get Last Error returns ERROR_ACCESS_DENIED. As a corollary of missing server authentication, applications using NTLM can also be vulnerable to a type of attack known as a “reflection” attack.

This privilege is not required for the local system account or accounts that are members of the administrators group. This latter allows an attacker to hijack a user’s authentication conversation to a legitimate server and use it to authenticate the attacker to the user’s computer.

Even though it may be possible for the client and server to authenticate using Kerberos this is prevented by the explicit selection of NTLM.

How to Fix this Error The fix for this error is to select the Negotiate package in place of NTLM.

Different online services have different ways of handling accounts and authentication, so the account manager uses pluggable .

Authenticators (which may be written by third parties) handle the actual details of validating account credentials and storing account information.

How this is done will depend on the particular Network subsystem being used by the client or server. You should consult the documentation on the particular library or API set that you are using.
