Re: [gridsam-discuss] National Grid Service & GridSAM

Arif,

Once you've imported your keys/certificate into the OMII Client JKS 
keystore, make sure
the authentication mechanism can read it. The way the system accesses 
the keystore is
by reading the configuration file 
'<omii_client_dir>/conf/crypto.properties'.
Make sure the config values in that file are correct for your keystore.
