I think the article would do well with a list of known GSSAPI implementors. I could find the following public ones:

• Heimdal[1],
• MIT[2],
• Globus [3],
• Shishi [4],
• SSPI [5] (wire-compat only),
• SAP [6],
  • SAP is not a GSS-API implementation; it simply uses GSS-API SamHartman 21:28, 16 October 2007 (UTC)[reply]

but who else? - DLeonard 04:42, 1 October 2006 (UTC)[reply]

As for mechanisms, Martin Rex in Nov 2004 wrote to kitten-at-ietf.org with this info:

I was surprized how many independent (mostly proprietary) implementations
of gssapi mechanism exist.  I got to know then only because the vendors
asked for interoperability certification of their product with our
application.  I don't know how many of them (if any) are or have
ever participated in IETF activities.  Here's a quick list of companies:

ietf mechanism:         Company (Country)

   Kerberos 5             MIT, CyberSafe, CA/Platinum, Microsoft, heimdal
   SPKM                   Entrust (CA), Shym (US), Baltimore (US)

proprietary mechanisms:

   AM-DCE                 Bull (FR)
   (propr.)               Sagem (FR)
   sdti,rsakeon,trustnet  TFS-Tech (SE) former RSA/SDTI
   safelayer              Safelayer (SP)
   NEC Secureware         NEC (JP)
   itsec                  UBS/ITsec (CH)
   Adnovum GSSv2          UBS/Adnovum (CH)
   ISign/secui            Penta Security Systems (South Korea)
   Sisler                 Siemens India (India)
   cpro                   Mecomp (RU)
   lissi                  Lissi (RU)
   kobil                  Kobil GmbH (DE)
   T-Secure               secunet/Telekom (DE)

how many do you recognize?

I read the article and noticed several problems that I don't have time to work on now so I decided to document them.

• I don't understand how RADIUSis a competing technology
• I think the proper abbreviation is GSS-API not GSSAPI; see RFC 2743.
• I'm not convinced that impersonationa is incompatible with IETF GSS-API. in particular GSS-API does provide a credential delegation mechanism. The only interisting thing behind impersonation is that you are able to tell the local OS to use the credential for everything including local access checks. For every GSS-API operation you can use the delegated credential just as in Windows. However you need a specific OS call to use that for local operations and that is in fact outside the scope of GSS-API.
