Goose fixed Boris. The ownerships for xdmcp, gdm and some users and groups
were bolluxed. Goose fixed as many as he had time for and says we can write
a script (tcl project?) that will correct such problems in future server
upgrades.
I dropped Boris at the lab on my way home from MLUG, and we'll install it
Thu.
