Does anyone know the purpose of the file .ICEauthority that is generated in your home directory when you log into CDE in an NIS environment?

I believe that ICEauthority is used for authentication between two XWindows servers. It is essentially a list of clients that are allowed access to your server. Is it causing you any problems?? You can delete it and it should be rebuilt automaticaly.

This file was referenced in a login error that was generated after an old NIS map was pushed to a client. I was just curious as to the purpose of the file. The problem has since been corrected.

ICE is used to provide a skeleton for session management and
is used by session managers, such as dtsession. dtsession,
of course, has its own methods, but uses the underlying
technology as a matter of course. ICE stands for Inter-Client
Exchange and it "provides a generic framework for building
protocols on top of reliable, byte-stream transport connections."

The best source of reference on ICE is the URL quoted earlier.

The O'Reilly book Programmer's Supplement for Release 6 has
some information on libICE and libSM.
ICE it is part of X11R6 - not any release of the OS. libICE exists at
10.20 as well, only dtsession doesn't use it.

The 2 instances I know that can cause ICE errors are :

1) Users sharing the same $HOME directory, but having differeing UID's.
2) NIS problems where the users nis passwd files are not being read correctly ...

So if you had a NIS problem it would fit ...
