[Freeipa-devel] joining rhel5 ipa clients to rhel 7 server failing caused by time offset.

[Michael Gregg]

I was trying to join my rhel 5 client to a rhel 7 domain, and getting 
the following error:

[root at oracle ~]# ipa-client-install -p admin -w <pw> -U
root        : ERROR    LDAP Error: Connect error: error:14090086:SSL 
routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
root        : ERROR    LDAP Error: Connect error: error:14090086:SSL 
routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
Unable to find IPA Server to join
Installation failed. Rolling back changes.
IPA client is not configured on this system.

Tried to verify the cert with this:

openssl s_client -host iota.testrelm.test -port 443 -CAfile /etc/ipa/ca.crt

This came up with this error code:

Verify return code: 9 (certificate is not yet valid)

After syncing the clock, everything worked al-right. I tried googling 
around a bit, but I couldn't find any specific articles about this problem.

Does this sound like a troubleshooting and repair step that is 
documented somewhere already?
