![]() ![]() Even so, the user will at least have the ability to log into their laptop and use any applications that are installed locally on the device.Įven though cached credentials are primarily used as a mechanism for allowing users to login locally when they are working from outside of the office, cached credentials have another important use. The user will not be able to access any of the resources on the corporate network because no connection to the network exists and the user's authentication was not processed by a domain controller. Because Windows supports the use of cached credentials, however, the cached credentials residing within the user's device can process the authentication request. If it were not for cached credentials, then the user would be unable to log on to their device because there is no domain controller available to process the logon request. This is where cached credentials come into play. If, on the other hand, the user is working from home using the same laptop but has no connection to the corporate network, then the Active Directory cannot process the user's logon request. In that type of situation, the Active Directory would authenticate the user's credentials when the user logs on. Suppose for a moment that a user is working from a domain-joined laptop and is connected to the corporate network. ![]() Cached and stored credentialsĬached credentials are a mechanism that is used to ensure that users have a way of logging into their device in the event that the device is unable to access the Active Directory. Perhaps the most easily overlooked cause of account lockouts, however, is the use of cached credentials.īefore I explain why cached credentials can be problematic, let's first consider what the Windows cached credentials do and why they are necessary. However, this is far from being the only thing that can cause an account to become locked.Īnother common cause, for example, is an application or script that is configured to log into the system using an old password. When a user account becomes locked out, the cause is often attributed to a user who has simply entered an old or incorrect password too many times. ![]()
