Description Jenny Severance 2009-09-18 20:43:29 UTC
Description of problem:

Install output:

[root@jennyv2 yum.repos.d]# ipa-server-install 

The log file for this installation can be found in /var/log/ipaserver-install.log
This program will setup the IPA Server.

This includes:
  * Configure the Network Time Daemon (ntpd)
  * Create and configure an instance of Directory Server
  * Create and configure a Kerberos Key Distribution Center (KDC)
  * Configure Apache (httpd)
  * Configure TurboGears

To accept the default shown in brackets, press the Enter key.

Enter the fully qualified domain name of the computer
on which you're setting up server software. Using the form
Example: master.example.com.

Server host name [jennyv2.bos.redhat.com]: 

The domain name has been calculated based on the host name.

Please confirm the domain name [bos.redhat.com]: 

The IPA Master Server will be configured with
Hostname:    jennyv2.bos.redhat.com
IP address:
Domain name: bos.redhat.com

The server must run as a specific user in a specific group.
It is strongly recommended that this user should have no privileges
on the computer (i.e. a non-root user).  The setup procedure
will give this user/group some permissions in specific paths/files
to perform server-specific operations.

The kerberos protocol requires a Realm name to be defined.
This is typically the domain name converted to uppercase.

Please provide a realm name [BOS.REDHAT.COM]: 
Certain directory server operations require an administrative user.
This user is referred to as the Directory Manager and has full access
to the Directory for system management tasks and will be added to the
instance of directory server created for IPA.
The password must be at least 8 characters long.

Directory Manager password: 
Password (confirm): 

The IPA server requires an administrative user, named 'admin'.
This user is a regular system account used for IPA server administration.

IPA admin password: 
Password (confirm): 

The following operations may take some minutes to complete.
Please wait until the prompt is returned.

Comment 1 Martin Nagy 2009-09-18 21:28:21 UTC
It seems that the reason is that you had an old /var/lib/ipa/ca_serialno file on your machine. A recent patch changed the format of this file and ipa-server-install --uninstall didn't delete it, therefore the installation failed because it didn't recognize the file.

I will address the issue, but for now I'm lowering the priority and severity, as this bug has an easy work-around.

Comment 4 Rob Crittenden 2009-09-23 12:54:58 UTC
I guess ideally we'll handle both formats and initialize the new format with the old CA serial number.

The reason that the file isn't deleted on uninstall is so if you install again you get new serial numbers for all the certs and avoid errors where you have the same cert (and serial number) but different keys.

Comment 5 Martin Nagy 2009-09-23 13:06:12 UTC
In that case this is NOTABUG. The error Jenny encountered was there because the format of that file changed. Rob, do you think it would at least be worth it marking the file a %ghost?

Comment 6 Rob Crittenden 2009-09-23 14:00:02 UTC
Well, I think we should handle it a bit more gracefully than a backtrace in any case.

Yes, probably worth making this a %ghost file.
