Please show a short but complete program (with the user credentials elided!) that replicates the problem. Also show us the error message you get and the behaviour you expect. This helps us help you better, because we can then diagnose what error happens and maybe reproduce your situation.

The DBI documentation says that ->connect returns undef on failure, so your error must be somewhere else.
