Notes for QA: this bug is to ensure that if the krb5_realm is manually set for an 'id_provider = ipa' or 'auth_provider = ipa' domain, that the krb5_realm is used for all kerberos-related activities.

This is relevant if ipa-client-install is run with the --realm command. We need to ensure that when krb5_realm is set in sssd.conf, it is honored everywhere.

Verified using:
sssd-1.5.5-0.20110405T0615z.el6.x86_64

installed ipa server as -
ipa-server-install --setup-dns --forwarder=10.14.63.12 -p Secret123 -P
Secret123 -a Secret123 -r QWQW

and verified sssd.conf, and default.conf have the right entries:
sssd.conf:
section for [domain/testrelm] includes:
krb5_realm = QWQW
ipa_domain = testrelm

section for [domain/default] includes:
krb5_realm = QWQW

default.conf includes:
basedn=dc=qwqw
realm=QWQW
domain=testrelm
xmlrpc_uri=https://rhel61-server5.testrelm/ipa/xml
ldap_uri=ldapi://%2fvar%2frun%2fslapd-QWQW.socket

also verified kinit
