The other thing you should do is file a TAR with Oracle on this issue, 
describing the security and interoperability issues it causes for you and 
asking them to fix the problem.  The more people who report problems caused 
by the use of such ancient Kerberos, the higher likelyhood they will fix it.



If you felt it was appropriate, you might point out that NIST is in the 
process of withdrawing FIPS 46-3, after which federal agencies will not be 
permitted to use single DES for the protection of federal information.  The 
full notice was published in the July 26, 2004 Federal Register (vol. 69, 
no. 142, pp. 44509-44510) as docket number 040602169-4169-01.
