PRVF-4007  User equivalence check failed for user grid

This error occurs during RAC pre checks for crsinst. This is optional step for RAC installation which shows any pending pre checks to make your job simpler during installation.

This pre check is very helpful in prior to 11gR2 release as in 11gR2 release and next release you can make ssh configuration during clusterware installation. So simply you can ignore this error.
