[Openca-Users] dual key pair support

[venki]

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.
