After upgrading to Mac OS 8.0 and applying MCLUPD3.BIN, Macintosh users cannot login by double clicking on a Volume Alias that was created when connected via AppleTalk NDS mode (NetWare Encryption) or Bindery Emulation mode (Standard Apple UAM). Same issue occurs when a volume alias is placed in the Startup Items folder for auto-mounting.
The following error occurs:
The alias "Vol_Name alias" could not be opened, because the shared disk "Vol_Name" could not be found on the network.
Note: The same symptoms occur on a NetWare 3.1x environment too - refer to TID#2919183.
WORKAROUND
Login via MacIPX (using the NetWare Directory Browser Application) or as GUEST via AppleShare (Bindery mode) in Chooser, then create an alias of the Volume or Directory in Volume.
