Error 0x8007052E: "Login Failure: unknown user name or bad password."

Error 0x8007052E Login Failure unknown user name or bad password

This error is very common when supplying specific credentials in an LDAP bind. In many cases, this error simply indicates that the credentials supplied were incorrect. However, there are some other, subtler reasons why this error often occurs.

  • The username is specified in the wrong format. See Chapter 3 for valid username formats.
  • The format used for the username is not compatible with the authentication flags being used. Chapter 3 covers authentication flags in detail.

Furthermore, Chapter 8 provides useful information on general security issues with binding to the directory, and Chapter 12 provides an entire section on scenarios for LDAP-based authentication.
