Subject Re: Auth bug in 3.2.1?
Date Sat, 14 Apr 2001 23:01:20 GMT
Hi Thom,

Thanks for posting a solution! I was just about to start exploring
JDBCRealms.

Did you post this as a patch to the Tomcat-dev list? If not, that might be
the best first step, since it looks like you've solved the problem. Who
knows how long it will take for someone on the Dev side to read through this
list and find this thread...
