PCNS multi-forest config?

Hi,

Forest A contains FIM services, and a copy of the users from Forest B (via FIM provisioning).

Forest B contains the users, and this is where users will change passwords from workstations.

We would like passwords to replicate from Forest B to Forest A.

Have setup a 2 way trust between the forests, and then:

1. Have installed PCNS in Forest B only
   
2. Then, ran the following in Forest A: setspn -A PCNSCLNT/DC1.ForestA.com ForestA\FIMSyncService
   
3. Then,, ran the following in Forest B: pcnscfg.exe ADDTARGET /N:FIMServer /A:FIM.ForestA.com /S:PCNSCLNT/DC1.ForestA.com /FI:"Domain Users" /FE:"Domain Admins" f:3
   

Are the above steps correct?

Thank you,

SK
