Hi,

In my company, we're pitching a Kerberos-based solution to authenticate tens of 
thousands of Linux users to Active Directory.  To increase the likelihood of 
approval by the higher-ups, we really need to eliminate all perceived security 
holes.  

Although preauthentication helps some, Kerberos version 5 is susceptible to 
offline, brute force, password attacks on the initial AS-REQ.  I saw some 
discussion about this from a few years ago in the archives, but nothing 
recently.  Is there a solution to this issue yet?  If not, what progress has 
been made, and what direction is being taken?  I do have some familiarity with 
MIT Kerberos source code internals, having interfaced some the library's 
low-level profile and DNS SRV functions to hack out support for Microsoft's 
extended version of DNS SRV.   Depending on how big the task is, I might be 
able to spend some time at work to code a solution.

Thanks.

Brian
