[Openca-Users] dual key pair support

[venki <ave...@re...>]

how  can we generate dual key pairs for an entity in openca pki =
software. Does it require separate program to generate dual keys or we =
can manage with current openca pki solution itself.

I tried to generate  two certificates for an entity with same input =
values.  while on CA signing the certificate, it gives

"Error 690
  Configuration error A  valid certificate with same DN exists"

How can we manage dual key pairs for an entity in openca? any light on =
this will be more useful. And also eager to know mail clients which =
support dual key pairs. That is , the mail client should pick up the =
right signing key and decrypting key.=20
