[Freeipa-users] gssapi sasl error - only picking up short hostname when running ipa-client-install (and failing)

[Les Stott]

Martin,

there is no entries in /etc/hosts for the freeipa servers on the client.
the clients hosts own entry is there with fqdn first.

Because you mentioned it, i added the hostname of both freeipa server to the hosts file on the client. It actually ran and setup the client. However it did get the following errors at the end after it did kerberos config....

=======
Configured /etc/krb5.conf for IPA realm MYDOMAIN.COM
Traceback (most recent call last):
  File "/usr/sbin/ipa-client-install", line 2377, in <module>
    sys.exit(main())
  File "/usr/sbin/ipa-client-install", line 2363, in main
    rval = install(options, env, fstore, statestore)
  File "/usr/sbin/ipa-client-install", line 2135, in install

  File "/usr/lib/python2.6/site-packages/ipapython/kernel_keyring.py", line 99, in del_key
    real_key = get_real_key(key)
  File "/usr/lib/python2.6/site-packages/ipapython/kernel_keyring.py", line 45, in get_real_key
    (stdout, stderr, rc) = run(['keyctl', 'search', KEYRING, KEYTYPE, key], raiseonerr=False)
  File "/usr/lib/python2.6/site-packages/ipapython/ipautil.py", line 295, in run
    close_fds=True, env=env, cwd=cwd)
  File "/usr/lib64/python2.6/subprocess.py", line 639, in __init__
    errread, errwrite)
  File "/usr/lib64/python2.6/subprocess.py", line 1220, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory
=======

Is that normal?

Do i need to add entries to the hosts file on every client?

Regards,

Les

The FreeIPA server has records for HTTP/ freeipa-1.mydomain.com at MYDOMAIN.COM<mailto:freeipa-1.mydomain.com at MYDOMAIN.COM>. I can see these in the web interface. I believe this is where it is stumbling.

Everything I've found says make sure you have working dns, make sure you can reverse lookup ip's, make sure hostnames are fqdn, make sure /etc/hosts on server has ip's for servers listed with fqdn first and shortname second. I've done all that.

What about /etc/hosts on the clients? Do they also have FQDN first in case they
have server IP in there?
