I was left scratching my head over this for a couple of days myself.

Ah thanks. This worked like a charm. I didn't think of that, because I tried to authenticate and enroll on the existing trustpoint (but the router would not let me, complaining with some errors). It looked like the trustpoint was created when creating the CA, so I assumed the router was auto enrolled. That seems so simple to create a new trustpoint, I just couldn't see the solution right in front of my face.

Your issue is the key server needs to enroll to itself for a digital certificate.

Create a new trustpoint on the CA/KS with a different name and auth/ enrol to it.
(Copy the trustpoint from the GM for instance but change the name).
Your isakmp is failing as it cant authenticate.

your rekeying for gdoi wont work yet either as you need to configure rekey authentication using your mypubkey under the group.

I have to routers acting as GDOI members and I have on router acting as a key server. The routing acting as a key server is also a CA

Here is my configs:

key server and CA:

crypto pki server IOSCA
 issuer-name c=CA,cn=iosca.digitalcortex.local,l=calgary
 grant auto
 database url flash:
!
crypto pki trustpoint IOSCA
 revocation-check crl
 rsakeypair IOSCA
!crypto isakmp policy 1
 encr 3des
 group 2
!
!
crypto ipsec transform-set trans1 esp-3des esp-sha-hmac
!
crypto ipsec profile get1
 set transform-set trans1
!
crypto gdoi group group1
 identity number 1
 server local
  ! Incomplete unicast rekey configuration
  ! Rekey authentication is not configured
  rekey retransmit 10 number 2
  rekey transport unicast
  sa ipsec 1
   profile get1
   match address ipv4 101
   replay counter window-size 64
  address ipv4 172.16.113.2
!
access-list 101 permit ip 0.0.0.0 255.255.255.0 0.0.0.0 255.255.255.0

GDOI members:

crypto pki trustpoint IOSCA
 enrollment url http://172.16.113.2:80
 revocation-check crl

crypto isakmp policy 1
 encr 3des
 group 2
!
crypto gdoi group group1
 identity number 1
 server address ipv4 172.16.113.2
!
!
crypto map mymap 10 gdoi
 set group group1
!
interface Serial0/0
 ip address 172.16.2.2 255.255.255.0
 encapsulation frame-relay
 frame-relay lmi-type cisco
 crypto map mymap


The clocks are all syned with ntp and I was able to get certificates from the CA on the GDOI members. I think the issue I am having is due to the fact that the CA is on the same router as the key server. I would like to get this working. Is there something I must do to make the key server recognze the fact that the trustpoint is the router itself? Here is an expert from the logs on the key server. It seems the key server does not like the certificate supplied by the member router
