[LON-CAPA-admin] Access Server Problems

[Mark Lucas]

Todd,

from a non-guru, did you rebuild totally from scratch, or did you
restore parts of the /home/httpd directory? (I always start access
servers totally fresh). Did you change machines underneath?

I've confirmed that I can log in, access resources on oucapa2, but not
under the csm domain. Do you have security certificates set up that
might have caused grief?

Mark
