Subject Re: DRDA Password Encryption (SECMEC_EUSRIDPWD and SECMEC_USRENCPWD)
Date Mon, 20 Jun 2005 23:36:37 GMT
It looks like there are a lot of separate issues around client/server 
security.  Perhaps we should open a top-level JIRA issue and then create 
sub-tasks that identify each of these?  That would allow someone or 
someones interested in improving security to have a one-stop-shop to 
understand what needs to be fixed...
