Description Scott Poore 2012-06-10 16:19:54 EDT
Description of problem:

occasionally sssd is left running after an ipa-server-install --uninstall.  On an attempted re-install using ipa-replica-install, I am seeing ipa-replica-conncheck errors.

Version-Release number of selected component (if applicable):

How reproducible:
Very but not always.  I'm seeing this in automated testing.

Steps to Reproduce:
1. <Install IPA on RHEL 6.3 Master>
2. <Create Replica package file>
3. <Install IPA on RHEL 6.3 Replica>
4. ipa-replica-manage del $REPLICA # on master
5. ipa-server-install --uninstall -U # on replica
6. ipa-replica-install -U --setup-dns --no-forwarders -w $ADMINPW -p $ADMINPW /path/to/replica-info-$REPLICA.gpg
Actual results:

Error seen at end of ipa-replica-conneck from ipa-replica-install:

# tail ipareplica-conncheck.log
    ticket_lifetime = 36000
    renew_lifetime = 36000
    forwardable = true
    krb4_convert = false

2012-06-10T18:16:32Z DEBUG stdout=
2012-06-10T18:16:32Z DEBUG stderr=kinit: Invalid message type while getting initial credentials

Then checking to see what's running:
[root@qe-blade-06 log]# ps -ef|grep sssd
root     12741 12699  0 14:13 pts/0    00:00:00 grep sssd

root     17290 17255  0 Jun09 ?        00:00:00 /usr/libexec/sssd/sssd_ssh --debug-to-files

Expected results:

ipa uninstall cleanly stops sssd.

Additional info:

If I stop sssd, ipa-replica-conncheck works though:

# service sssd stop
Stopping sssd: [  OK  ]

# /usr/sbin/ipa-replica-conncheck --master qe-blade-09.testrelm.com --auto-master-check --realm TESTRELM.COM --principal admin --hostname qe-blade-06.testrelm.com --password Secret123

The following list of ports use UDP protocol and would need to be

Connection from replica to master is OK.
