[Freeipa-users] Cannot obtain CA Certificate

[John Moyer]

Peter, 

	Thanks for the response, I just checked out my security group settings, I did have some ports blocked, however, allowing them did not help.   I installed mmap on the client and did a port scan of the server and got the follow: 

PORT    STATE SERVICE
22/tcp  open  ssh
53/tcp  open  domain
80/tcp  open  http
88/tcp  open  kerberos-sec
389/tcp open  ldap
443/tcp open  https
464/tcp open  kpasswd5
636/tcp open  ldapssl
749/tcp open  kerberos-adm

I tried to enroll again and got the same error as seen here: 


Synchronizing time with KDC...

ipa         : ERROR    Cannot obtain CA certificate



Thanks,

I am using CentOS 6 to do all this testing on, with the default IPA packages provided from CentOS.   I had a fully operational proof of concept finished fully scripted to be built without issues.   I shutdown and started these as needed to show to people to get approval for the project.   The other day the client stopped enrolling to the IPA server, I have no idea why I assume a patch pushed out broke something since it is a fully scripted install. It does get the most recent patches each time I stand it up so it definitely would pull any new patches that came out.
