I have resolved the install issue.

Great!


The installer is a bit sloppy and makes some bad assumptions.  The problem turns out to be that the directory server setup seems to be running as dirsrv, not root.  Ipa-server-install (more specifically dsinstance.py) writes out the file /var/lib/dirsrv/boot.ldif.  But it does so as root, using root’s umask.  It doesn’t do a check to make sure dirsrv can read this file before spawning an external process to create the directory server.  Part of security best practices recommended by the CIS group as well as others is to set root’s umask to 0077.  With this setting in place, dirsrv is unable to read /var/lib/dirsrv/boot.ldif, which causes setup-ds.pl to fail when executed from ipa-server-install.  I modified dsinstance.py to not remove the file and checked it after a failed install.  It was written properly, so I changed the permission on it to 666 and re-ran the install.  It succeeded.

Opened https://fedorahosted.org/freeipa/ticket/1282


I’m now back to where I started, which is a partly working ipa install.  Kinit takes 75 seconds to complete.

Seems like a DNS timeout or something related to the name resolution.

 I still can’t get to the UI.  I’m now going to uninstall again, change root’s umask to 022, and see if that fixes any more of the problems.

The UI does not start for me if you try to run FF from the root shell. I forget about this frequently and just upgraded to F15 and hit it again.

If you have a normal user shell, kinit from that shell as admin and start browser from it you should have all the right context to access UI.

Yes, I mentioned in the first email I had attempted that.  I just ran the uninstall 10 times in a row.  Same errors:

As a test I’ve manually run setup-ds.pl accepting all of the defaults.  It works fine and installs successfully, creating the slapd-freeipa (which is the hostname) instance.  I then ran remove-ds.pl on the slapd-freeipa instance and re-ran the ipa uninstall.  When I attempted to reinstall ipa, it detected an existing ds.  I did a locate for dirsrv and found logfiles from an instance called slapd-ARC-NASA-GOV, which should be my default freeipa dirsrv instance.  To try to clean this up, I ran setup-ds.pl and chose custom and created a slapd-ARC-NASA-GOV instance, and then immediately removed it with remove-ds.pl.  I then re-ran ipa-server-install, which this time did not detect an existing directory server.  However, the ipa-server-install again failed in the same location.

Re: [Freeipa-users] Difficulty installing freeipa
 I’ve given up on freeipa v2 due to lack of compatibility with hosts I manage.  This is all on freeipa v1.  The server started as Fedora 13, and I upgraded to Fedora 14 in an attempt to fix the problems.
 
 [root freeipa ~]# uname -r
 2.6.35.13-91.fc14.x86_64
 [root freeipa ~]# rpm -qa 'ipa*'
 ipa-client-1.2.2-6.fc14.x86_64
 ipa-server-selinux-1.2.2-6.fc14.x86_64
 ipa-python-1.2.2-6.fc14.x86_64
 ipa-admintools-1.2.2-6.fc14.x86_64
 ipa-server-1.2.2-6.fc14.x86_64
 [root freeipa ~]#
 
 I’m not doing anything special at this point.  I’m not even trying to get clients added.  I’m trying to do a basic install of ipa-server, with no extra arguments.  That claimed to succeed but wouldn’t work, I tried to fix it, uninstalled, any attempts to reinstall failed.  So right now I’m simply trying to get the ipa service back to any kind of functioning status without re-installing the OS.
 
 

 Ah this is all old 1.2 IPA.
 Have you tried
 ipa-server-install --uninstall
 
 Might require several attempts until all the errors are cleared.

 Is it all on F13?
  The IPA v2 can't be built on F13 as there are many dependencies missing that we rely on. There are two many parts this is why we had to move to the later versions of F15. We just did not have any options. So the server you built might in fact be completely broken. I do not know how to fix it. It looks like you have some instances of the DS left over in a misconfigured state.
  
  You can try running ipa-server-install --uninstall 4-5 times. That might clear things a bit.
  
  But let us get back to the original problem.
  Freeipa can be used with the LDAP+Kerberos configuration on the clients. You do not need to have latest and greatest.
  There was a nice article referenced in some of the earlier threads on the list:
  
 http://www.aput.net/~jheiss/krbldap/howto.html <http://www.aput.net/%7Ejheiss/krbldap/howto.html>  <http://www.aput.net/%7Ejheiss/krbldap/howto.html>
 
 You can configure very old clients to use IPA as NIS server.
 Let us know how else we can help.
  Thanks
