514: An authentication package has been loaded by the Local Security Authority

On this page

Event 514 is logged once at startup for each authentication package on the system.

An authentication package is a DLL that encapsulates a given form of authentication, such as NTLM or Kerberos. The Local Security Authority calls into the appropriate authentication package during the logon process to find out if the user is authentic.

Although a third party can develop an authentication package, few do so. The standard packages that come with Windows Server 2003 are as follows: 

  • Microsoft Authentication Package V1_0
  • Wdigest
  • Microsoft Unified Security Protocol Provider
  • Schannel
  • NTLM
  • Kerberos
  • Negotiate

The security implication of event 514, realistically, is low. Although a rogue package could cause great harm by stealing credentials at the time of logon, the effort required in developing and installing a rogue authentication package is significant.
