codeCollaborator server svn+ssh connectivity problem

Hi Support,

Thanks for info. I have configured using public authentication
key on my server.

 My question:

How do i configure public key or passphrase in
codeCollaborator server and configured public key passphrase on svn server.

 Please find the attached error in access cco-server to
cco-client and my public key config command list

 Please provide me steps for adding public key in code
collaborator server.
