[Freeipa-users] Cannot obtain CA Certificate

[Steven Jones]

Hi,

My poor 2 ideas,

You could try web browsing to the IPA server to see if the cert is there (wild guess).

~/ipa and see if there is a CA cert you can import.

Is the client pointing at the IPA server for its DNS?

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,

Hi John,

I ran into a similar issue with setting up a 2.2 client with a 3.1 server.
It turned out to be that port 80 wasn't open on the freeipa server.
I would check your ports and see if the right ones are open.
I also find that setting up the SRV and TXT records in your dns zone makes setting up clients a lot simpler.

Hello all,

I am having an issue using IPA 2.2.0.   I am trying to put together a proof of concept set of systems.  I've stood up 2 servers on AWS.   One is the server one is the client.   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.

After investigating I am getting this error when I try to manually enroll the client.  I haven't been able to find any reference to this error anywhere on the net.  Any help would be greatly appreciated!  Let me know if any additional details are needed.
