MYSQL upgrade problem

I’m having a problem with one of my web applications after the database server was upgraded to mysql 4.0.

If I move the table to a database that is still on a mysql 3.23 server, everything continues to work.

The application in question is the Horde authentication module.

I’m wondering if anyone knows if anything has changed in the way that mysql 4.0 returns strings or encoded fields to php.

I can give more details if anyone has any thoughts about this…
