Are you running on an x86/x64 platform using the Xorg server? There was a regression introduced into S10 update 4 when the version of Xorg was updated. The Xorg server is supposed to be compiled with Sun-DES support (this is a DEFINE in the Makefile). Due to a bad merge this was not defined, so the underlying mechanism for authenticating roles (not root) to the X server was not included in the build. This seems to account for the problems you are having.
A patch was issued, but I don't have the number available now. I think you need an updated Xorg server. --Glenn This message posted from opensolaris.org
