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. --Vesso Shaon, ABS (Arif) wrote: > Thanks. I have installed the certificates as per the instructions in > the OMII manual.
