How to see which resource broker are configured for your UI?

The configuration files are VO-specific.

For AFS UI installation:

 /afs/cern.ch/project/gd/LCG-share/3.0.0/edg/etc/lhcb/edg_wl_ui.conf 

For local UI installation:

/opt/edg/etc/geant4/edg_wl_ui.conf
/opt/glite/etc/geant4/glite_wms.conf
/opt/glite/etc/geant4/glite_wmsui.conf

How to request for a certificate for another VO at CERN?

There is a new certificate authority at CERN at https://ca.cern.ch/ca so probably the instructions below are obsolete (to be checked).

Create a new certificate request with CN = YOUR NAME - VO:

~gridca/scripts/cert-req -dir $HOME/.globus-geant4 -cn "Jakub Moscicki 2231 - geant4"

Use your existing certificate to sign the request and send it to CA:

openssl smime -sign -to service-grid-ca@cern.ch -subject "Certificate Rekey Request"  -signer ~/.globus/usercert.pem -inkey ~/.globus/userkey.pem < /afs/cern.ch/user/m/moscicki/.globus-geant4/userreq.pem  | /usr/sbin/sendmail -t

The original instructions are at: http://service-grid-ca.web.cern.ch/service-grid-ca/default.html
