Question:

Why are my Intel Macs getting a Connection Failed 2 error?

Answer:

This error only happens if you are connecting to Microsoft Services for Macintosh (SFM) using the custom Microsoft User Authentication Module (MSUAM). This issue does not affect ExtremeZ-IP because it uses either the built-in DHX or Kerberos User Authentication Modules which work fine on the Intel Macs.

The “Connection Failed 2” error message is probably caused by a Type 2 OS error trickling up as a connection failure. Generally a Type 2 error is a result of allocating memory and then trying to write more data than will fit in that memory. This could be caused by the UAM trying to use a data length that was byte-swapped on the Intel Mac.

Although Microsoft has not released an updated UAM for the Intel Macs, Apple seems to have quietly included one in the Mac OS X 10.4.6 update.
