I have wiped out my prior installation, and started again. This time, I
used safe settings, installed OES Server, then ran YAST and installed
MySQL and PHP, then rug to patch everything, and it seemed to have run
all right, but now when I try to go to NoRM, I get "You have received an
invalid certificate. Please contact the server administrator or email
correspondent and give them the following information: Your certificate
contains the same serial number as another certificate issued by the
certificate authority. Please get a new certificate containing a unique
serial number."

I installed this server (every time) in it's own tree, and have not
retained anything from the prior installs. The TID that comes up when I
do a search tells me to run PKIDIAG.NLM (which I would be thrilled to do
if only this were a NetWare server).
