This has come up in the ccie written. If I understand this subject correctly AUTO , sends out packets to try and match the 2 devices up with regards to speed and duplex. If your getting connection problems this would be a speed issue. If its some sort of packet loss/error then this could be a duplex problem. I have always configured the CAT port manually so there isnt any problems.
