rcons uses xCAT credentials to verify. 
In /etc/conserver.cf file it has the following:

config * {
  sslrequired yes;
  sslauthority /etc/xcat/cert/ca.pem;
  sslcredentials /etc/xcat/cert/server-cred.pem;
}

Can you check those 2 files?  I am just curious on the error you gave us:
console: SSLVerifyCallback():  issuer  = /CN=xCAT CA 
console: SSLVerifyCallback():  subject = /CN=xCAT CA 

My  /etc/xcat/cert/server-cred.pem look like this:
# cat /etc/xcat/cert/server-cred.pem

Yes to all

Removed the certificates and recreated using xcatconfig -c

I even did a killall -9 conserver

Could it be a version of openssl, it is above the rhels6.4 standard level. 
Prob updated a few weeks back

Hi Arif, 
     Have you run makeconservercf and "service conserver stop; service 
conserver start" (not service conserver restart) after xcatconfig? 
If it still does not work, can you remove /etc/conserver.cf and run 
makeconservercf?

Hi all, 

I have checked the mailinglist and googled the info, but cannot find a fix 


I have done a "xcatconfig -c" several times (as suggested by Lissa on 
another post), with also removing the /etc/xcat/{cert,ca}, but I am having 
no luck. 

xCAT version 2.8.3, upgraded from 2.8.1 today, and we had the same issue 
before the upgrade 
OS: CentOS 6.4 

Maybe I have missed looking at something. 


# rcons blade089 
console: SSLVerifyCallback(): error with certificate at depth: 1 
console: SSLVerifyCallback():  issuer  = /CN=xCAT CA 
console: SSLVerifyCallback():  subject = /CN=xCAT CA 
console: SSLVerifyCallback():  error #19: self signed certificate in 
certificate chain 
console: SSL negotiation failed 
3788:error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate 
verify failed:s3_clnt.c:912: 

thanks in advance
