I've added three tests:
- verify-full specified, CN and username match -- should connect ok
- verify-full specified, CN and username do not match -- should fail
- verify-ca specified, CN and username do not match -- should connect
ok (This is current behaviour)

This wouldn't be desirable, I think...
Most applications will probably supply the password in the connection
string anyway, so there would be only one connection, right?

I've shortened the clientcert=verify-full specific error-message to
"certificate validation (clientcert=verify-full) failed for
user \"%s\": CN mismatch"
slightly offtopic opinion:
While creating the test cases, I stumbled upon the problem of missing
depencies to run the tests...
It's complicated enough that the binaries used by these perl tests are
not named similar to the packages which provide them (the 'prove'
binary is supplied by 'Test-Harness'), so maybe in the interest of
providing a lower entry-barrier to running these tests, we could give a
more detailed error message in the configure script, when using --
