Finding your company's alumni in a target employer

Hello all,

As the title says - if you've identified a company to apply / interview for, is there a way to use LinkedIn to find someone working there who used to work at your current company? Assuming they're open to chatting, they would be great sources of info (having made a similar transition) and a potential referral source. 

I thought LinkedIn used to have this feature but can't seem to get it to work anymore - anyone else have the same experience?

Cheers.
