It looks to be similar to the nss/curl issues we saw a few weeks ago. This was done using RHEL 6.1 images in Amazon:

-----------
AMI ID:     ami-5ef90237
AMI Label:  309956199498/RHEL-6.1-Starter-EBS-x86_64-4.1-Access

[root@cds-1 rhui-1.2-5Server-i386]# cat /etc/issue
Red Hat Enterprise Linux Server release 6.1 (Santiago)

RPM Versions:
nss-3.12.9-9.el6.x86_64
curl-7.19.7-26.el6_1.1.x86_64
libcurl-7.19.7-26.el6_1.1.x86_64
-----------

I used a base RHUI install with the following versions:
Pulp:       0.208
RHUI Tools: 2.0.38
Grinder:    0.105

RHUI Manager generated an "identity" certificate the CDS uses to connect to the RHUA. This certificate is munged by RHUI Manager to remove the PKCS8 issues we saw previously. Snippet from the cert:

-----BEGIN RSA PRIVATE KEY-----
MIIEowIBAAKCAQEA2DYRVNYjgHvMX0/+usy64usHQpIug1qazPPFWPFSuwacgU4m


I am able to use wget to download the repomd.xml file from the Pulp server to the CDS, which means a number of things aren't an issue: the content is successfully in place, SSL is set up correctly, authentication isn't a problem, the CDS can resolve the server at "rhua", firewalls aren't in the way, etc.

The issue is that grinder and curl cannot sync from the Pulp server (RHUA) to the CDS. It's still likely NSS/curl related, but I'm not sure of why this is once again an issue.

I attached the output below of running with grinder, wget, and curl.


Using Grinder:
