Does anybody know what is @#$%! "user equivalence"? I have 2 nodes, I have all the elements and here is what I get:

[oracle_at_oracle20 cluvfy]$ ./runcluvfy.sh stage -pre crsinst -n
oracle20,oracle21 -verbose

Performing pre-checks for cluster services setup

Checking node reachability...

Check: Node reachability from node "oracle20"

  Destination Node                      Reachable?              
  ------------------------------------  ------------------------
  oracle20                              yes                     
  oracle21                              yes                     

Result: Node reachability check passed from node "oracle20".

Checking user equivalence...

Check: User equivalence for user "oracle"

  Node Name                             Comment                 
  ------------------------------------  ------------------------
  oracle21                              failed                  
  oracle20                              failed                  

Result: User equivalence check failed for user "oracle".

ERROR:
User equivalence unavailable on all the nodes. Verification cannot proceed.

Pre-check for cluster services setup was unsuccessful on all the nodes.
[oracle_at_oracle20 cluvfy]$

I can reach both nodes without a password:
[oracle_at_oracle20 cluvfy]$ ssh oracle21

[oracle_at_oracle21 ~]$ ssh oracle20-priv

[oracle_at_oracle20 ~]$

WTF is "user equivalence"? The installation procedure for RAC is really, really foobar.
