Hello All,

Thanks for everyones help with this. Below is the actual working script I used to accomplish my task of sshing to over 500 remote RHEL LINUX servers using ssh, run remote commands, grep for IPA server and then outputt to a file or the screen.

SAMPLE /etc/sssd/sssd.conf:
###################################
Code:
[root@xyz_server ~]# cat /etc/sssd/sssd.conf
[domain/]
cache_credentials = True
krb5_store_password_if_offline = True
krb5_realm = UNIX-PROD
ipa_domain = sampledomain.com
id_provider = ipa
auth_provider = ipa
access_provider = ipa
ipa_hostname = ipahostname.domain.com
chpass_provider = ipa
ipa_server = ipaserver.domain.com, ipaserver2.domain.com
ldap_tls_cacert = /etc/ipa/ca.crt
[sssd]
services = nss, pam, ssh
config_file_version = 2
domains = sampledomain.com
[nss]
[pam]
[sudo]
[autofs]
[ssh]
