Hi All, One of my application they are using cyrus-sasl to authenticate before it logged into MySQL database. I have upgraded MySQL from 5.0 to 5.5 Before upgrade it works fine and application is not able to connect to database after the upgrade. I have rolled back the upgrade and now its running on 5.0 The problem is still application is not able to connect to the database. The question is, How to verify the cyrus-sasl related things are there and fine. Any help would be much appreciated. -Sarathy
