Description Scott Poore 2012-10-26 03:18:18 UTC

Description of problem:

I would expect that any necessary client install (including via ipa-replica-install) would configure necessary changes when a cross domain trust is in place.

After having to re-configure/re-install a replica, I noticed that /etc/sssd/sssd.conf was missing subdomains_provider line.

ipa-client-install, ipa-replica-install should properly configure client config files for trusts if trusts are enabled for the environemt.

Version-Release number of selected component (if applicable):
ipa-server-3.0.0-105.20121022T2338zgit3488770.el6.x86_64

How reproducible:
Unknown


Steps to Reproduce:
1.  Install IPA Master and Replica
2.  Install AD Server
3.  Setup trust to AD domain
4.  on replica:  ipa-server-install --uninstall -U
5.  on master: ipa-replica-manage -p PASSWORD del REPLICA --force
6.  on master: ipa-replica-prepare -p PASSWORD --ip-address=REPLICA_IP REPLICA
7.  on replica: sftp MASTER:/var/lib/ipa/replica-info-REPLICA.gpg 
8.  on replica: ipa-replica-install -U --setup-ca --setup-dns --forwarder=DNSFORWARDER -w PASSWORD -p PASSWD replica-info-REPLICA.gpg
  
Actual results:

configs missing.  at the very least /etc/sssd/sssd.conf is missing subdomains_provider = ipa line.

Expected results:

all trust related configs should be handled by ipa install commands.
