Problem Solution:
There was no problem with username/password I was using.

The problem I experienced was that the Sybase server had too many idle connections lying around (probably because our network dropped out prior to previous connections disconnecting correctly and we had finally reached our pool limit).

I restarted the Sybase server & it resolved the issue. (It would have been cleaner to kill the idle connections)
