Problem with jdbc realm in tomcat

Greetings,

I recently upgraded Tomcat from 4.1.24 to 5.0.16 on a FreeBSD 5.1 server.
On this server I have a web application using the JDBCRealm for access
authentication, postgresql is the database engine. Anyway, this application
works fine under Tomcat 4.1.24 but, it does not appear to be consulting the
postgresql tables under 5.0.16 and access to the application is denied. I
do not see any error messages logged in any log file that give me a hint as
to any problem.

I have gone over the configuration multiple times and can not find any problems.
Configuration of this web application was simply copying the postgresql.jar
file to jakarta-tomcat-5.0.16/common/lib/postgresql.jar and copying the
application xml file to jakarta-tomcat-5.0.16/webapps/app.xml

Was wondering if anyone here are aware of any issues with the JDBCRealm when
migrating to Tomcat 5?

thanks
