Finally I decided to fall back to pulp-generated CA cert and key. I invoked
pulp-gen-ca-certificate and got the following:
[root@nms ~]# ls -lZ /etc/pki/pulp/
-rw-r-----. root apache unconfined_u:object_r:pulp_cert_t:s0 ca.crt
-rw-r-----. root apache unconfined_u:object_r:pulp_cert_t:s0 ca.key
To achieve this, I had to hard-code CA_CRT variable in
pulp-gen-ca-certificate since the script was setting this variable to '#',
though I have the following in /etc/pulp/server.conf:
[security]
cacert: /etc/pki/pulp/ca.crt # Deprecated! See above description for
details.
cakey: /etc/pki/pulp/ca.key # Deprecated! See above description for
details.
CA_KEY variable was set up correctly
But even after I got new CA key and cert at correct paths, I still get the
following error:
RequestException: POST request
on /pulp/api/v2/actions/login/ failed with 500 - error signing cert request:
Signature ok
subject=/CN=admin:admin:5571b5b4cfbac030922d8c3d

I even tried to remove comment lines after settings values in server.conf -
no better
Does anybody have any idea why this may be happening?
Thanks!
