Description Rob Crittenden 2011-03-17 14:26:48 UTC

Description of problem:

On both ipa-server-install and ipa-client-install we should check that the hostname returned by the system is all lowercase. Failing to do so may cause issues to programs trying to guess the host principal name in the keytab. They may try to use the mixed case name and fail to match the lower case name as krb libraries consider principal names case-sensitive.

Comment 5 Rob Crittenden 2011-03-17 16:32:05 UTC

Test on both client and server the hostname in /etc/hosts with mixed-case.

Remove mixed case from /etc/hosts.

Test on client with: ipa-client-install --hostname=<mixed-case hostname> ...

Test on server with: ipa-server-install --hostname=<mixed-case hostname> ...

Test on client and server by running: hostname=<mixed-case hostname> and then run the respective installer.

verified with version:
ipa-client-2.0.0-20.el6.x86_64

# ipa-server-install --setup-dns --forwarder=10.14.63.12 --hostname=RHEL61-server5.testrelm -r TESTRELM -p Secret123 -P Secret123 -a Secret123 
Install fails with error:
 Invalid hostname 'RHEL61-server5.testrelm', must be lower-case.


# ipa-client-install  --hostname=RHEL61-client.testrelm
Invalid hostname 'RHEL61-client.testrelm', must be lower-case.
