Users are most commonly locked out and cannot be validated by the ValidateUser method when the MaxInvalidPasswordAttempts property is exceeded within the time specified in the PasswordAttemptWindow property or when too many attempts have been made to log on using the wrong password.
If the EnablePasswordReset property is true, when a user is unlocked the counters for bad passwords are reset.
The provider uses a subtree search starting at the search point specified in the connection string. See the ActiveDirectoryMembershipProvider class topic for more information about connection strings.
Leading and trailing spaces are trimmed from the username parameter value.
