Red Hat Bugzilla – Bug 1007469
When in IPA server mode, SSSD should map trusted forest subdomains to root domain realm
Last modified: 2015-09-23 10:40:08 EDT
This bug is created as a clone of upstream ticket: https://fedorahosted.org/sssd/ticket/2080 SSSD writes down domain/realm mapping information for Kerberos-enabled applications. This information should include mapping from subdomains' DNS domains to the trusted forest Kerberos realm. Right now only DNS domain of the forest root domain is mapped to the trusted forest Kerberos realm. This is needed for IPA KDC to correctly issue referrals to the trusted forest root domain when handling access to services in the trusted forest subdomains.

Temporarily moving bugs to MODIFIED to work around errata tool bug
To verify this ticket you should check the SSSD-generated krb5.conf include file /var/lib/sss/pubconf/krb5.include.d/domain_realm_IPA_REALM on a FreeIPA host with trust to an AD forest with more than one domain. In this file all domain-REALM pairs of the AD forest should be listed in the [domain_realm] section and in the [capaths] section should see entries like FOREST.MEMBER = { IPA.REALM = FOREST.ROOT IPA.REALM = { FOREST.MEMBER = FOREST.ROOT } for every domain in the forest except the forest root.
