Windows xp wireless validating server certificate
This field contains the X.500 address (also referred to as the LDAP distinguished name) of the object whose identity is being asserted.As mentioned in my previous blog entry on the X.509 certificate, this is a throw back to the roots and original intent for PKI: directory services.
topic=/help.domino.admin.doc/DOC/H_KEY_USAGE_EXTENSIONS_FOR_INTERNET_CERTIFICATES_1521_OVER.html): In addition to validating the identity of the certificate holder an application may validate the purpose that the certificate is authorized for to ensure it is valid for its current use.
This validation is what prevents any non-CA certificate from acting as a certification authority and issuing certificates.
Once a certificate is issued the AIA path cannot be changed without reissue, therefore the location used to publish these certificates must be thoroughly thought out.
The AIA field allows for either HTTP or LDAP paths to provide flexibility in publishing locations.
Later, when version 3 of the X.509 standard was passed, the “Subject Alternative Name” (sometimes referred to as a “SAN” field) was added allowing the issuer additional flexibility in specifying the identity of the authenticating entity.
Out-of-the-box this provided options to identify the certificate owner in any of the following ways (ref:
The alternative is to present the AIA path using HTTP, a more common and Internet-friendly means of distribution.
When using HTTP ensure that the web servers publishing the AIA path are highly available and scalable to handle requests from every client that may need to validate a certificate issued by the CA.
By default, the client will try to use the certificate’s AIA path unless the issuer’s certificate is published to the client’s intermediate certification authorities (Sub CA) store.
Windows and Active Directory provide a number of ways to publish these certificates which will be discussed below.
Certificate validation is implemented differently based on the application validating the certificate, the type of identity being validated (i.e.Tags: Adult Dating, affair dating, sex dating
